Re: [PLUG] search and replace multiple files?

[John Fiore <fiorejp@yahoo.com>]

This post was from a while ago.  I saved it because I
thought that it might come in handy.

Today was the first day that I tried using it, but I'm
getting an error.

If I create a simple file called "file1", which just
contains the text "foo" in certain places, and try
running the command as you've mentioned:

      perl -pie 's/foo/bar/' file1

I get the error:
     Can't open perl script "s/foo/bar/": No such file
or directory

I'm using bash, but the same thing occurs if I'm using
tcsh.  I'm probably doing something stupid.  Any
ideas?

Thanks.

John
