You want to use the -i and -p options. Do a perldoc perlrun for a complete list of Perl options.

Your script should look like:

#!/bin/perl -w -i .bak -p
s/foo/toto/g; 
s/^\s*//;

This will do the substitution on each line of the file(s) passed as arguments and save the original files with a .bak suffix.
