Replace Perl Module name in all Perl scripts

I want to replace a Perl module name in all my Perl Scripts in the cgi-bin directory. How is it possible?

I have the following statement in my scripts

use myUtil;

I want to change it to

use myUtil777;

You can use perl itself

for filename in *.pl
do
perl -p -i.bak -e "s/myUtil/myUtil777/g" $filename
done

find . -name *.pl -type f | xargs perl -pi -e 's/myutil/myutil777/g'

Rahul.
