Use Sed (v2gnu/sed118b.zip).  It's a batch editor.  For example, the 
following will replace "foo" with "fubar" in the file foo.txt and put it 
into fubar.txt:

		sed 's/foo/fubar/g' foo.txt > fubar.txt

If you want to rewrite foo.txt itself, use `cat' (from Textutils, 
v2gnu/txt122b.zip), like this:

	cat foo.txt | sed 's/foo/fubar/g' > fubar.txt

(When Sed is not given input files, it reads its stdin.)

The quotes in the Sed command are only required if the text you are 
replacing includes whitespace.
