Convert p4 cygwin commands to p4 win commands

Here’s a simple little script which allows me to use p4.exe from cygwin.  Perforce actually releases a p4.exe for cygwin, but I wanted my p4win and p4.exe to be able to use the same client spec.  This isn’t possible when one requires a root starting with “C:\” and the other requires “/cygdrive/c/”.  

 

This script works by expanding and window-izing all arguments after the p4 command.

 

Here is a series which shows the transformation.

• p4 edit README
• p4 edit /home/gwarner/foo/README (where foo is a symbolic link)
• p4 edit /cygdrive/c/perforceRoot/blah/blah/blah/README
• p4 edit C:\perforceRoot\blah\blah\blah\README

 

Ta da!
