[PLUG] text search/replace

[Rogan Creswick]

If you need to do this in only one file, then most text editors worth
their name can do it for you. in vi:

:1,$s/oldexpr/newexpr/g 

will do it. emacs has the ability also, but the keystrokes to do so
escape me at the moment.

If you need to do so on many files there are any multitude of ways to
do this in perl alone (not to mention awk, etc..).

this should work:

perl -pi -e "s/oldexpr/newexpr/g" file1 file2 file3

or use find to locate the files..

find . -name "*.lisp" -print | xargs perl -pi -e "s/oldexpr/newexpr/g"

to apply the reg.exp to all lisp files in this directory and it's sub
dirs (the -print is optional with many versions of find).
