Many Files - Change

I am using C-shell .

I would like to change the contents of many files at once
i.e. change say the occurrence of 'xyz' in many files to
'abc' .
All the files are in one directory .

I guess I need to create an executable file - I've tried one
starting with '# /bin/csh -f' and this works OK .

Thanks - Brian Roberts

here's a script that will do it:

#!/bin/csh
foreach i (*)
sed s/"xyz"/"abc"/ < $i > tempfile
mv tempfile $i
end

answer I have received solves my problem .
I am very pleased with this .
I am not sure about your grading system re
excellent and good - as I don't know how easy my
question was to answer for an expert .

There also exists a program called "fgres" - fast grep and substitute, available from several ftp servers.
