Substitution does not work on multiple files Can't Post
Hello,

I need to change an email addresse in ca. 800 files.
I tried this:
Code
perl -pi -e 's/Old@email.com/New@email.com/g'
That command worked for a while but unfortunately didn't change anything.

Is my version too old?

Code
perl -v This is perl, v5.8.4 built for sun4-solaris-64int

You failed to give the name of the files to be changed.

It should be something like this:

Code
perl -pi -e 's/Old@email.com/New@email.com/g' filename*.*

Yeah, I should have seen it (I juste made a large program full of regexes on email addresses recently), but my eye was immediately caught by the fact that you did not give input file names.
