I would like to run a command in cleartool.
I am, however, unable to understand how do I launch this cleartool from Rational Clearcase.
Is it a plugin for ClearCase?
(I am using Clearcase explorer on Windows 7)
It is a command line interface (see IBM man page, and "Working at the command line").
It supposes that your $PATH (or %PATH% on Windows) environment variable references the <ClearCase installation directory>/bin.
Open a shell (like a DOS windows in windows, or ksh/bash/zsh on Unix/Linux) and type:
cleartool
That will open a sub-shell in which you can type cleartool command like lsvob.
I prefer, however, typing cleartool in the native shell:
cleartool --ver
cleartool lsvob
...
(instead of typing those commands within a cleartool session) That allows for a better error trapping and recovering process, directly handled in the native shell.
Note: above is for ClearCase 7.x.
For CCRC, or ClearCase 8.x (which is using ClearTeam Explorer, a modern version of CCRC), you would be using rcleartool.
