jeff,
I am drieux. What I would recommend is something old school, in which you go with something like code:
#!/usr/bin/perl -w use strict; my ($find, $replace) = @ARGV; while(<STDIN>) { $_ =~ s/$find/$replace/; print $_; }
then you can do:
[jeeves: 22:] echo "I am Manish" | ./simple_filter Manish Boyish I am Boyish [jeeves: 23:]
if you then put your script in one of the directories which are in you PATH, as I do with my $HOME/bin, then it will be findable.
As you want to 'grow it out' to handle the error cases such as not having enough arguments, and more and more complex RegEx, then you can style it as you like.
HTH.
ciao drieux
