7/7     I want to use perl for some inplace substitution a la
        perl -p -i.bak -e 's/pattern/replacement/g' but I want to know if
        my pattern will be matched correctly.  I've tried
        perl -pe 'print if /pattern/' * but that just prints all the lines.
        What's the right way to do this?
        \_ -p implicitly prints the line. Try -n instead.
           \_ thanks, is there a perl manual section that describes CLI opts?
              \_ from "man perl"
                 perlrun             Perl execution and options
                 so... "man perlrun"
                 \_ argggg.... thanks.
