check for file in $PATH
in [Perl]
|
From: cerr on 15 Mar 2010 13:24 Hi There, My perl script depends on a binary that may be in $PATH and i would like to check for that file. How can I verify if the file is present in $PATH without hard coding a full path? Thanks, Ron

Or simply use the external "which" utility. Or just call it, maybe with innocent arguments, and analyse the return value for the error code. jue
