CGI and Command Line Scripts
Programs on the server performing actions such as rendering, saving and renaming topics.
These scripts are located in the
bin
and
tools
directories. This topic describes the interfaces to some of those scripts. All scripts in the
bin
directory can be called from the CGI (
Common Gateway Interface) environment or from the command line. The scripts in the
tools
directory can only be called from the command line.
CGI Scripts
Details on CGI scripts located in the
bin
directory.
Note that a blank in the 'Default' column means that the parameter
is not required, and has no default.
required means the
parameter is required, and has no default. text
in italics describes
default behaviour if no value is given.
CGI environment
In the CGI environment parameters are passed to the scripts via the URL and URL parameters. Environment variables are also used to determine the user performing the action. If the environment is not set up, the default user is used (usually
guest
).
Command-line
You
must be have the
bin
directory on the perl path to run the scripts from the command line.
To avoid issues with file permissions,
run the scripts as the web server user such as nobody
, www-data
or www
.
If running scripts under the control of cron, install the crontab under the
web server user.
Parameters are passed on the command line using two possible formats:
- Traditional command line "switch" style format:
-name value
, The "-" prefix for the keyword is required.
$ cd /usr/local/foswiki/bin
$ save -topic MyWeb.MyTopic -user admin -action save -text "New text of the topic"
- Keyword format:
parameter=value
. A "-" prefix is optional.
$ cd /usr/local/foswiki/bin
$ save topic=MyWeb.MyTopic user=admin action=save text="New text of the topic"
All parameters require a value, even if that is the empty string. Note that parameters passed on the command-line should
not be URL-encoded.
Note: If any of the arguments will contain utf-8 strings, (ie. when entering a Unicode topic name), you must run the command
using the perlrun argument
-CA
. For example:
$ cd /usr/local/foswiki/bin
$ perl -CA ./save -topic MyWeb.MyÜtf8Töpic -user admin -action save -text "Text with »Äëïöü« utf8 characters."
For more details on the perl command line arguments, see
http://perldoc.perl.org/perlrun.html.
"Authentication" in the command line environment
Unlike the CGI environment, the default user for command line operations is
AdminUser
.
- The
-user
parameter is specific to the command line and is not recognized by in the web environment. It allows a user to be specified without requiring that the password be supplied. It is only active from the command line.
- The
-username
/ -password
parameters are processed by the authentication system and require the password be authenticated. Depending upon the authentication implementation, it may or may not be usable in the command line environment.
When calling a
tools
script from the command line, you normally need to be cd'd to the =bin directory e.g.
$ cd bin
$ ../tools/mailnotify -q -nonews -nochanges -Main -System
Context
Each script sets a Foswiki
context
to signal to plugins and other components the environment that they are running. In addition to the per-script context, two additional contexts are optionally set:
-
command_line
is set if there is no CGI query object available.
-
static
is set by scripts that render static content like PDF or other offline publishing tools
A comprehensive list of core context identifiers used by Foswiki is found in the
IfStatements
Common parameters
All the scripts accept a number of common parameters. The first two components of the URL after the script name are taken as the web and the topic, respectively. Standard URL parameters are:
Parameter |
Description |
Default |
cover |
Specifies temporary skin path to prepend to the skin path for this script only (see Skins) |
|
debugenableplugins |
During debugging it can be useful to selectively disable all but a subset of plugins. This parameter allows the caller to specify a comma-separated list of plugins that should be enabled. It can only be used when $ENV{FOSWIKI_ASSERTS} is set to 1 in bin/LocalLib.cfg . |
|
foswikioriginalquery |
The original query that was being made before a redirect for user confirmation was required. |
|
foswiki_redirect_cache |
Foswiki sometimes caches long lists of parameters that must survive over a sequence of browser redirects. This parameter identifies one of these caches. The parameter value is a "magic number" that uniquely idenitifies a file in the working/tmp directory. These files have a very short lifetime, and are destroyed when the cache is read. |
|
logout |
requests the LoginManager to log the current user out (this happens at the begining of the request so will terminate any other operation requested) |
|
refresh |
If the Foswiki page cache is in use, setting this parameter will invalidate the cache. Valid values are cache , on and all . See PageCaching for more information on the page cache. |
|
response |
Used as part of the request validation process. |
|
skin |
Overrides the default skin path (see Skins) |
value of the SKIN preference |
t |
While the t parameter is not actively used by any scripts, it is used when building links to scripts such as edit , to ensure that each edit link is unique. This stops the browser from trying to use a cached reply from a previous call to the script. |
generally set to current time, in seconds |
topic |
Overrides the web.topic path given in the URL (specify Web.TopicName, or TopicName in combination with defaultweb below) |
|
defaultweb |
a default value for web, which is over-ridden by specifying either a web in the topic param above, or in the url location (used for selecting a web in a webform) |
|
user |
Command-line only; set the name of the user performing the action. Note: this usage is inherently insecure, as it bypasses webserver login constraints. For this reason only authorised users should be allowed to execute scripts from the command line. |
|
validation_key |
part of cross-site scripting protection. Any request sent from browsers that might change data stored on the server must carry a key that indentifies the source of the request. |
|
preserve_vk |
part of cross-site scripting protection. Normally a validation key is expired once it has been used once. However non-HTML5 browsers can't handle this, so the validation key has to be preserved for re-use. |
|
<any name> |
Any other parameter name passed to the script is passed through for possible use by the script. This is typically only applicable to the edit , save and view scripts. |
|
Where revision parameters are required, individual versions are identified by positive, non-zero integers. Versions start with 1 and are sequencial. For compatibility reasons, Some scripts accept revision numbers with '1.' (or even 'r1.') prepended to the number, but this usage is deprecated and should be corrected when encountered.
Note: Prior releases of Foswiki would accept the undocumented username
and password
parameter on any script.
Foswiki 1.1.9 restricts this to the view
script and only on POST transactions unless overridden in the Foswiki configuration.
attach
Despite the name, this script doesn't actually attach a file to a topic - for that, use
upload
. This script is part of the transactions sequence executed when a file is uploaded from the browser. it just generates the "new attachment" page for a topic.
Parameter |
Description |
Default |
filename |
Name of existing attachment (if provided, this is a "manage attachment" action) |
this is a "new attachment" action |
changes
Shows all the changes in the given web.
The
changes
script can receive one parameter:
Parameter |
Description |
Default |
minor |
If 0, show only major changes. If 1, show all the changes (both minor and major) |
show major changes |
The main difference between invoking this script and using
WebChanges is that
WebChanges is based on a
%SEARCH%
, while this script reads the
changes
file in each web, making it much faster.
NOTE: The result from
changes
script and the topic
WebChanges can be different, if the
changes
file is deleted from a web. In particular, in new installations the
changes
script will return no results while the
WebChanges topic will.
configure
is the browser script used for inspection of, and changes to, the site configuration. None of the parameters to this script are useable for any purpose except
configure
. See
configure.
edit
The
edit
script understands the following parameters, typically supplied by HTML input fields.
A major role of the
edit
script is new topic creation. Parameters that are mainly relevant to new topic creation are marked with
Parameter name |
Description |
Default |
action |
If action=text , then hide the form. If action=form , then hide the normal text area and only edit the form. |
edit both |
breaklock |
If set, any lease conflicts will be ignored, and the edit will proceed even if someone is already editing the topic. |
|
cmd |
Admin only features, see below |
|
contenttype |
Optional parameter that defines the application type to write into the CGI header. May be used to invoke alternative client applications |
text/html |
formtemplate |
Name of the form to instantiate in the topic. Set to none to remove any existing form. |
|
notemplateexpansion |
Do not expand any macros in the template topic. (see New topic creation below) |
expand |
onlynewtopic |
If on , error if the topic already exists |
edit existing topic |
onlywikiname |
If on , error if the name of a topic being created is not a WikiWord |
allow non-wikiword names |
redirectto |
If the user continues from edit to save, and if the save (or cancel) process is successful, save will redirect to this topic or URL. The parameter value can be a TopicName , a Web.TopicName , or a URL. Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl} ). |
|
rev |
Lets you specify a specific revision to use as the basis of the edit. |
latest |
template |
Allows you to specify a different skin template. Overrides any setting of EDIT_TEMPLATE . |
|
templatetopic |
The name of the template topic, copied to get the initial content for a new topic. (see New topic creation below) |
|
text |
Set the text to be edited. If this parameter is not given, the text is taken from the existing topic (if it exists) |
|
topicparent |
Sets the parent topic. Set to none to remove parent. Set to topic name to change parent, leave empty to keep existing parent. |
keep existing parent |
<any name> |
This can be used in two ways; first, if the topic has a form with a field called <any name>, it will set the value of that field. Second, it can be expanded in the topic text during topic creation - see New topic creation below |
|
The following options are
only available to the site Administrator. They can "rewrite history" and should be used with caution only when absolutely necessary.
Parameter name |
Description |
Default |
cmd=delRev |
Administrators only delete the most recent revision of the topic - all other parameters are ignored. You have to be an administrator to use this, and not all store implementations will support it. This option returns you to an editor for the current version, but the edit is ignored, and save will delete the latest revision. |
|
cmd=repRev |
Administrators only replace the text of the most recent revision of the topic with the text in the text parameter. text may include embedded meta-data tags. As far as possible, the original author and date of the revision being replaced are retained. You have to be an administrator to use this, and not all store implementations will support it. |
|
Skin notes:
The
EDIT_TEMPLATE
preference (or the
template
parameter) can be used to override the default 'edit' template on a per-web or per-topic basis.
The
action
parameter works by loading the
editform.tmpl
or
edittext.tmpl
templates in place of the standard
edit.tmpl
. If an
EDIT_TEMPLATE
has been defined, then it replaces
edit
, e.g. if
EDIT_TEMPLATE=specialed
and
action=form
then the template used will be
specialedform
In most skins that are based on the default templates (such as
PatternSkin) you can easily change the
Edit
and
Edit WikiText
buttons to append the
action
parameter, by setting the
EDITACTION
preference to the value
text
or
form
(You can always get back to editing the whole topic by removing the
action
parameter from the URL browser Location window, and reloading the edit window).
New topic creation :
The string AUTOINC followed by one or more digits anywhere in the topic name will be converted to a number such that the resulting topic name is unique in the target web. However this doesn't happen until the topic is saved.
When a new topic is created using edit, the topic isn't actually created until the edit is saved. The content of the new topic is initialised according to the parameters you pass.
-
templatetopic
- defines the full name (web.topic) of a topic to use as a template for the new topic. The template topic is copied and, unless notemplateexpansion
is set, the following macros are expanded in the topic text: URLPARAM
, DATE
, SERVERTIME
, GMTIME
, USERNAME
, WIKINAME
, WIKIUSERNAME
, USERINFO
. (see TopicTemplates)
-
text
- use this as the text of the topic. Macros are not expanded in this text. Overrides any text set in the templatetopic
.
-
formtemplate
- Overrides any form set in the templatetopic
.
-
notemplateexpansion
- given by templatetopic
. Use this when you want a verbatim copy of a topic.
-
onlynewtopic
and onlywikiname
are used to control validation of the new topic name.
- <any name> - besides the form field value setting described above, when creating a new topic,
%URLPARAM{"
<any name> "}%
in the templatetopic
will be expanded to the parameter value.
login
Used for logging in with TemplateLoginManager, and for interactive validation of operations that require user confirmation.
Parameter |
Description |
Default |
foswikiloginaction |
If 'validate', the login script is being used for interactive validation of an operation. Otherwise it is being used for login. |
|
foswiki_origin |

login
script will only accept the username and password fields when submitted with a POST.
logon
Used for logging in when Web Server authentication is being used (e.g. ApacheLoginManager). The script does nothing; it is purely a placeholder for triggering the login process. The webserver must be set up to require a valid user to access this script, thus triggering the webserver login process.
manage

resetpasswd
This script is
deprecated. Its functions are covered by the
manage
script.
rest
This REST (
Representational State Transfer) script can be invoked via http in the same way as the other scripts (see
Invocation Examples, below) to execute a function that is associated to a "subject" and a "verb" (see below). These functions are usually registered by plugins using the
Foswiki::Func::registerRESTHandler
method. The
rest
script will print the result directly to the browser unless the
endpoint
parameter is specified, in which case it will output a redirect to the given topic or url.
The
rest
script supports the following parameters:
Parameter |
Description |
Default |
redirectto |
Redirect to this topic or URL after successfully running the rest function. The parameter value can be a TopicName , a Web.TopicName , or a URL. Note: Redirect to a URL only works if it is enabled in configure (Miscellaneous {AllowRedirectUrl} ). |
None. |
password |
See username |
|
username |
If TemplateLogin , or a similar login manager not embedded in the web server, is used, then you can pass a username and password to the server (though see below for a preferred way to pass authentication information). |
REST scripts that require a topic context must use the standard
topic
parameter to pass the topic name, as the URL path is used to identify the REST function. If not defined, then the topic context in REST handlers will be
Main.
The function is free to use any other query parameters for its own purposes.
rest
authentication
If a REST operation requires a logged-in user but no user is logged in, then it will return a 401 status. In the case of the
TemplateLogin
login manager, this will include a
WWW-Authenticate
header starting with
FoswikiBasic
. This allows the status to percolate through to Javascript where it can be handled by your code. The
realm
in the
WWW-Authenticate
header is taken from the
{AuthRealm}
setting in
configure
, or the empty string if it is not set.
If you are using
TemplateLogin
, the preferred way to pass user login information back to the server is to use the
X-Authorization
HTTP header. This header is modelled on the HTTP Authorization header, as described in
http://www.ietf.org/rfc/rfc2617.txt, except that the scheme name
FoswikiBasic
is used instead of
Basic
. The user-id and password are combined with a : and base64 encoded. For example, if the user agent wishes to send the userid "Aladdin" and password "open sesame", it would use the following header field:
X-Authorization: FoswikiBasic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
When used with jQuery:
$.ajax({
beforeSend: function(xhrObj){
xhrObj.setRequestHeader("X-Authorization",
"FoswikiBasic QWxhZGRpbjpvcGVuIHNlc2FtZQ==");
}
});
The
rest
script should
always be configured to require authentication in any site that is using
ApacheLogin
. Otherwise there is a risk of opening up major security holes. So make sure you add it to the
{AuthScripts}
list in
configure
.
Note: As of 1.1.9, the
rest
script no longer will accept the username and password fields by default. If the prior behavior is required, it can be enabled in
bin/configure
by setting
$Foswiki::cfg{Session}{AcceptUserPwParam} = /^rest$/;
. Note that even with this enabled, the
rest
script requires that the username and password be entered using POST.
Invocation Examples
The
rest
script assumes that it will be called with URL in the form:
http://my.host/bin/rest/<subject>/<verb>
where
<subject>
must be the
WikiWord name of one of the installed
Plugins, and the
<verb>
is the alias for the function registered using the
Foswiki::Func::registerRESTHandler
method. The
<subject>
and
<verb>
are then used to lookup and call the registered function. If you need to
pass a topic name, then this is passed in the
topic
URL parameter.
As an example, the
EmptyPlugin has registered a function to be used with the
rest
script under the subject
EmptyPlugin and the verb
example.
The URL to call this function from a browser would be:
-

Tips
- You can use a tool like
curl
to upload files from the command line using this script.
- You can call upload easily from XmlHttpRequest in Javascript.
- You can directly invoke upload from the CLI script.__New with Foswiki 2.1__
- You must use the Perl CLI options '-CA' if the filename or any other arguments contains utf-8 (non-ASCII) characters.
- ex. Run from the bin directory:
perl -CA ./upload filepath="/path/and/filename.dat" filename="Ãttachname.dat" topic=Sandbox.ExistingÜtf8Topic
Note: The
upload
script can only be called via HTTP POST method. Make sure you specify
method="post"
if you call the
upload
script via a form action. It is not possible to call
upload
from an
<a href ...>
link.
view
Used for viewing topics.
Parameter |
Description |
Default |
contenttype |
Allows you to specify a different Content-Type: (e.g. contenttype=text/plain ) |
text/html |
raw |
-
on - show the text of the topic in a scrollable textarea. -
debug - as on , but also shows the metadata (forms etc) associated with the topic. -
text - show only the source of the topic, as plain text (Content-type: text/plain). Only shows the body text, not the form or other meta-data. -
all - show only the source of the topic, as plain text (Content-type: text/plain), with embedded meta-data. This may be useful if you want to extract the source of a topic to a local file on disc. |
|
rev |
Revision to view (e.g. rev=45 ) |
latest |
SEARCH<hex number> |
Identifies a result set that is being paged through |
|
section |
Allows to view only a part of the topic delimited by a named section (see VarSTARTSECTION). If the given section is not present, no topic content is displayed. |
|
template |
Allows you to specify a different skin template, overriding the 'view' template the view script would normally use. The default template is view . For example, you could specify /bin/view/System/CommandAndCGIScripts?template=edit. This is mainly useful when you have specialised templates for a Wiki Application. |
|
<any name> |
It can be expanded in the topic text during rendering and referenced in IF statements - See the VarURLPARAM macro and IfStatements |
|
For historical reasons, the view script has a special interpretation of the
text
skin. This skin cannot be redefined.
viewfile
Used for viewing attachments. Normally, a site will publish the attachments (
pub
) directory using a URL. However if it contains sensitive information, you will want to protect attachments using
AccessControls. In this case, you can use the
viewfile
script to give access to attachments while still checking access controls.
Instead of using the
filename
parameter, you can append the attachment name
to the end of the URL path (after the topic) e.g.
http://gsics.atmos.umd.edu/bin/viewfile/Webname/TopicName/Attachment.gif
Details on command line scripts located in the
tools
directory.
This is a fully functional command line interface to the Foswiki configuration. It is able to set and check configuration values, and to run wizards.
tools/configure [-search] [-getspec] [-getcfg] [-check] [-wizard] [-method] [-save] [-json] [-trace] [-help] [-noprompt] [-expert]
Note: if you need to pass in international characters, it needs to be run with the
perl -CA
command argument. (
perl -CAS
when running a new configuration bootstrap)
Function |
Usage |
Bootstrap a new install without helptext |
tools/configure -save -expert |
Bootstrap an installation containing international characters |
perl -CAS tools/configure -save |

geturl.pl
This is a very simple script to get the content of a web site, either using GET or POST. It is marked as
deprecated and might be removed in a future release. Its functions are covered by the standard
wget
and
curl
commands, which have the added advantage of performing authentication..
- Usage:
geturl.pl <host> <path> [<port> [<header>]]
- Example:
geturl.pl some.domain /some/dir/file.html 80
- Will get:
http://some.domain:80/some/dir/file.html
- Example:
geturl.pl POST some.domain /bin/statistics?webs=Sandbox
- Will post:
http://some.domain/bin/statistics?webs=Sandbox
triggering a statistics run
rewriteshebang.pl
Simple script to rewrite the
#!/usr/bin/perl
shebang lines specific to your local Perl installation. It will rewrite the first line of all your cgi scripts so they use a different shebang line. Use it if your perl is in a non-standard location, or you want to use a different interpreter (such as 'speedy').
tick_foswiki.pl
This script executes a number of non-essential regular administration tasks that will help keep your site healthy and happy, such as removing expired sessions and lease files.
It is intended to be run as a cron job or a scheduled task once a week. Example crontab entry:
0 0 * * 0 cd /usr/local/foswiki/bin && perl ../tools/tick_foswiki.pl
Note: The script has to be run by a user who can write files created by the webserver user.
Extensions, such as the
MailerContrib, also install tool scripts. Check the documentation of the extension for details.
extension_installer
This script will download and install, or remove an extension.
For more details, execute it from the Foswiki root directory with the
usage
parameter:
./tools/extension_installer usage
Note that this script is a generic version of the
_installer
script shipped with each extension. There are 3 ways to install a script using these scripts:
- Download
SomePlugin_installer
and execute it from the Foswiki root directory
- run
./tools/extension_installer SomePlugin
- the extension will be downloaded and installed
- Use the configure web interface to the Extensions Installer.
