Hi,
I would like to execute some commands in my .emacs only if there are
some files in the current PATH. The specific example is, I only want to
load a perforce library (p4.el) if I can find the executable p4 in the
path.
How can I do this? I couldn't find any way to either run a shell command
(through which I could run `which p4`), or read an environment variable
PATH, and then find all the files in it and see if p4 is there.
Any tips would be appreciated.
