Message-ID: <4B1CAC27.4060802@online.de> (raw)
Hi,
needed a check if a command exists on system.
Employed the following:
(defun system-command-exists-p (command)
"Return t if COMMAND is available on system. "
(let* ((cmd (format "type %s" command)))
(eq 0 (shell-command cmd))))
Any comments/suggestions?
Andreas
