Again, I don't use cygwin very often, but I know .bat files are scripts for the Windows cmd.exe shell, not for the cygwin shell, which uses bash or another unix shell. But maybe there is special handling built in to let it run cmd.exe scripts.


I am in cygwin and trying to use windows native gvim (I don't even have gvim in cygwin, just vim). I am using gvimdiff.bat to launch gvim with the files.
Like I said before the problem would be around the fact that any shell command started from the gvim instance launched from cygwin gives the error
/bin/bash -c "diff -v"
The system cannot find the path specified.
sheell returned 1

which means it is trying to use the bash to run these commands when it maybe should run cmd, but I don't know how to fix this.
