    man [ command_name ]


This command displays a reference page, the table of contents for the online documentation, or the product tutorial. The documentation that is displayed depends on the command context.

This command does not require a product license.

Displaying reference pages

The man command displays a specified online reference page in HTML or ASCII (UNIX® and Linux® only) formats. For cleartool and multitool subcommands, you can use any valid command abbreviation or alias. For example:

cmd-context man lscheckout


cmd-context man lsch

Full command name

cmd-context man lsco


UNIX® and Linux®: Using MANPATH

Reference pages are stored in subdirectories of versionvault-home-dir/doc/man. The man subcommand modifies the environment to include a MANPATH variable set to this directory. It then runs the UNIX® and Linux® man(1) command in a subprocess. Thus, the shell from which you invoke cleartool need not have MANPATH set.

If, however, you want to use the UNIX® and Linux® man command without going through cleartool or multitool, include versionvault-home-dir/doc/man in your MANPATH. For example:

setenv MANPATH /usr/catman:/usr/man:/opt/hcl/ccm/versionvault/doc/man

With the UNIX® and Linux® man command, you must match the reference page file name. The file names of cleartool subcommands have a ct_ prefix. The file names of multitool and multiutil subcommands have mt+ and mu+ prefixes, respectively.

% man ct_describe


% man mt+syncreplica


% man clearmake

Correct (not a cleartool subcommand)

% man describe

Incorrect (cleartool subcommand)

UNIX® and Linux®: Displaying the table of contents or tutorial

To display a table of contents or the product tutorial, use the keywords contents or tutorial instead of the name of a reference page.

UNIX® and Linux®: Changing the default HTML browser

To change the default HTML browser, use the environment variables CCASE_WEBSCRIPT, CCASE_NETSCAPE, and CCASE_NETSCAPE_OPT. For more information, see xcleardiff.

The UNIX system and Linux examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX system and Linux shells or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.
