TWiki CGI and Command Line Scripts
Programs on the TWiki server performing actions such as rendering, saving and renaming topics.
The TWiki scripts are located in the
twiki/bin
and
twiki/tools
directories. This topic describes the interfaces to some of those scripts. All scripts in the
twiki/bin
directory can be called from the CGI (
Common Gateway Interface) environment or from the command line. The scripts in the
twiki/tools
directory can only be called from the command line.
CGI Scripts
Details on CGI scripts located in the
twiki/bin
directory.
General Information
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 TWiki user is used (usually
guest
).
Command-line
You
must have the
twiki/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
or
www
.
Parameters are passed on the command line using '-name' - for example,
$ cd /usr/local/twiki/bin
$ save -topic MyWeb.MyTopic -user admin -method POST -action save -text "New text of the topic"
All parameters require a value, even if that is the empty string.
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 |
topic |
If this is set to a URL, TWiki will immediately redirect to that URL. Otherwise it overrides the URL and is taken as the topic name (you can pass Web.TopicName) |
|
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 authorized users should be allowed to execute scripts from the command line. |
TWikiAdminGroup |
method |
Commad-line only; set the HTTP request method. Some scripts requires the POST method under certain circumstances. In such a case, you need to specify the POST method to run the script from a command line. |
GET |
skin |
Overrides the default skin path (see TWikiSkins) |
|
cover |
Specifies temporary skin path to prepend to the skin path for this script only (see TWikiSkins) |
|
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) |
none (in which case this is a "new attachment" action) |
changes
Shows all the changes in the given web.
The
changes
script can receive one parameter:
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
configure
is the browser script used for inspection and configuration of the TWiki 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:
Parameter |
Description |
Default |
action |
Optional. Use the editaction template instead of the standard edit. If action=text, then hide the form. If action=form hide the normal text area and only edit the form. You can change the Edit/Edit Raw buttons to always append the action parameter in skins like Pattern and Classic by setting the topic or preference variable EDITACTION to the value text or form . To edit the topic once the EDITACTION is defined as form simply remove the action=form from the browser URL of the edit script and reload the edit window |
|
onlynewtopic |
If set, error if topic already exists |
|
onlywikiname |
If set, error if topic name is not a WikiWord |
|
templatetopic |
The name of the template topic, copied to get the initial content (new topic only) |
|
text |
Initial text for the topic |
|
topicparent |
The parent topic |
|
formtemplate |
Name of the form to instantiate in the topic. Overrides the form set in the templatetopic if defined. (will remove the form is set to 'none') |
|
template |
Specify a different skin template, overriding the 'edit' template the edit script would normally use. Use this for specialized templates in a TWiki Application. This parameter is not commonly used. |
|
contenttype |
Optional parameter that defines the application type to write into the CGI header. Defaults to text/html . May be used to invoke alternative client applications |
|
anyname |
Any parameter can passed to the new topic; if the template topic contains %URLPARAM{"anyname"}% , it will be replaced by its value |
|
breaklock |
If set, any lease conflicts will be ignored, and the edit will proceed even if someone is already editing the topic. |
|
redirectto |
If the user continues from edit to save, and if the save (or cancels the edit) 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 (Security setup > Miscellaneous {AllowRedirectUrl} ). |
|
t |
Provide a unique URL each time a topic is edited, typically specifying parameter t=%SERVERTIME{$epoch}% in an edit link. This is done to prevent browsers from caching an edit session, which could result in editing outdated content. The parameter name and value is arbitrary, but must be unique each time. |
|
Form field values are passed in parameters named 'field' - for example, if I have a field
Status
the parameter name is
Status
.
- The first sequence of ten or more
X
characters in the topic name will be converted on save to a number such that the resulting topic name is unique in the target web.
Note: Most skins support the definition of
EDIT_SKIN
, which is used as the value of the
cover
parameter in
edit
URLs. This allows you to override the default edit skin on a web, topic or user basis.
login

mdrepo
Used to retrieve and update data in
MetadataRepository.
Please read
MetadataRepository#mdrepo_script_from_command_line and
MetadataRepository#mdrepo_script_from_browser.
rest
This REST (
Representational State Transfer) script can be invoked via http in the same way as the other TWiki 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
TWiki::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.
The
rest
script supports the following parameters:
username |
If TemplateLogin , or a similar login manager not embedded in the web server, is used, then you need to pass a username and password to the server. The username and password parameters are used for this purpose. |
password |
See username |
topic |
If defined as the full name (including web) of a topic, then when the script starts up plugins will be passed this as the "current" topic. If not defined, then Main.WebHome will be passed to plugins. |
endPoint |
Where to redirect the response once the request is served, in the form "Web.Topic" |
The function is free to use any other query parameters for its own purposes.
Note: The
rest
script should
always require authentication in any TWiki that has logins. Otherwise there is a risk of opening up major security holes. So make sure you add it to the list of authenticated scripts if you are using
ApacheLogin
.
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
TWikiPlugins, and the
<verb>
is the alias for the function registered using the
TWiki::Func::registerRESTHandler
method. The
<subject>
and
<verb>
are then used to lookup and call the registered function.
<subject>
and
<verb>
are checked for illegal characters exactly in the same way as the web and topic names.
As an example, the
EmptyPlugin has registered a function to be used with the
rest
script under the subject
EmptyPlugin and the verb
example. Click below to see the
rest
script in action (run as
TWikiGuest).
Call the Plugin
Note that for Plugins to register REST handlers, they must be enabled in
configure
.

page.
The parameters are interpreted in according to the following rules.
- The first sequence of ten or more
X
characters in the topic name will be converted to a number such that the resulting topic name is unique in the target web.
- When the action is
save
, checkpoint
, quietsave
, or preview
:
- The new text is taken from the
text
parameter, if it is defined,
- otherwise it is taken from the
templatetopic
, if it is defined, (new topic only)

hidefile |
If defined, will not show file in attachment table |
|
filepath |
Local (client) path name of the file being uploaded. This is used to look up the data for the file in the HTTP query. |
|

$filename |
You can use a tool like
curl
to upload files from the command line using this script.
Note: The
upload
script can only be called via http POST method, not GET.
view
Used for viewing topics.
Parameter |
Description |
Default |
raw=on |
Shows the text of the topic in a scrollable textarea |
|
raw=debug |
As raw=on , but also shows the metadata (forms etc) associated with the topic. |
|
raw=text |
Shows 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. |
raw=expandvariables |
Similar to raw=text but TWiki variables are expanded. |
|
raw=all |
Shows 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. |
|
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. |
|
contenttype |
Allows you to specify a different Content-Type: (e.g. contenttype=text/plain ) |
|
rev |
Revision to view (e.g. rev=45 ) |
|
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 /do/view/TWiki/TWikiScripts?template=edit. This is mainly useful when you have specialized templates for a TWiki Application. |
|
topic |
redirects to show the specified Web.Topic, or, redirects to a URL, if allowed by {AllowRedirectUrl} and {PermittedRedirectHostUrls} configure settings |
|
createifnotexist |
If createifnotexist is set to 1 and in case the topic does not exist, it is created automatically on view. Useful to create topics automatically based on a specific template (see example below). Behind the scene, the view script redirects first to the save script, passing along all URL parameters. Thus all URL parameters of the save script can be used, such as templatetopic , topicparent and redirectto . Next, the save script creates the topic and redirects back to the view script (or displays an error in case there were any issues creating the topic). |
|
extralog |
Add additional text to TWiki log, next to the user agent string. Useful to log actions by cache scripts and crawlers. |
|
Example use of
createifnotexist
to link to the bookmark page of a user, and to create the page on the fly if needed:
[[%SCRIPTURL{view}%/%USERSWEB%/%WIKINAME%Bookmarks?createifnotexist=1&templatetopic=%SYSTEMWEB%.UserBookmarksTemplate&topicparent=%WIKINAME%][Bookmarks]]
For historical reasons, the
view
script has a special interpretation of the
text
skin. In earlier TWiki versions the
skin=text
parameter was used like this:
http://.../view/MyWeb/MyTopic?skin=text&contenttype=text/plain&raw=on
which shows the topic as plain text; useful for those who want to download plain text for the topic.
Using
skin=text
this way is
DEPRECATED, use
raw=text
instead.
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
TWikiAccessControls. 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.
https://mudconnector.su/do/viewfile/Webname/TopicName/Attachment.gif
In that case, determining the attachment file name is non-trivial -- please consider a file name having multiple dots and a file name having no dots.
As such, the process of determining the file name is put on the debug log if
debug=1
URL parameter is supplied.
Command Line Scripts
Details on command line scripts located in the
twiki/tools
directory.
geturl.pl
This is a very simple script to get the content of a web site. It is marked as
deprecated and might be removed (or enhanced) in a future TWiki release. Its functions are covered by the standard
wget
and
curl
commands.
- 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
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 TWiki 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_twiki.pl
This script executes a number of non-essential regular administration tasks that will help keep your TWiki 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/twiki/bin && perl ../tools/tick_twiki.pl
Note: The script has to be run by a user who can write files created by the webserver user.
