which_scm - Report Source Code Management system which_scm which_scm detects the Source Code Management (SCM) system in use, and prints a single line of text containing a one-word name for the SCM, followed by a space, and then the top-level directory path for the workspace. The typical usage within a ksh script is:

 which_scm | read SCM_TYPE CODEMGR_WS || exit 1

If CODEMGR_WS is set in the environment, then which_scm checks only that directory, assuming that it is the top of the tree. If CODEMGR_WS is not set, then which_scm searches upwards to find the containing workspace path, and reports that path. which_scm can detect the following types of SCM systems (these are the keywords used in the output format):

 cvs
 git
 mercurial
 rcs
 sccs
 subversion
 teamware

If the type of SCM in use is not known, then the string "unknown" is printed, and the path returned is $CODEMGR_WS (if set) or the current working directory. The command may exit with an error if the SCM could be detected, but is unusable. The following environment variable is used by which_scm:

CODEMGR_WS path to current workspace.

cvs(1) , git(1) , hg(1) , sccs(1) svn(1) , workspace(1)
