Re: find a forgotten shell command

you could write it completely in perl. Perl provide a powerfull grep to catch over list and many file access method thru File::* or simply glob() like

perl -le '$cmd="ls";foreach (split(/:/,$ENV{"PATH"})){print grep(/$cmd
+/, glob("$_/*"))} '

You could get inspired by the already made (in perl) unix command from PPT project to produce more granulated output.

Yep you are right. I didn't think of using glob, but I do know that Perl has a CORE::grep(). Nice job. But to which "already made (in perl) unix command from PPT" do you refer? -- Tommy Butler, a.k.a. TOMMY	[reply]

in that case ls and grep (the only non perl things of the original script) -- dominix	[reply]
