Perl as (a better) Grep Command
How it Works


 perl -wln -e '/RE/ and print;' F


 -wln: warnings, auto- carriage returns,
               auto- input processing
   -n: treat F as name of input file
   -e: execute program in following argument
 /RE/: Match regex against current line
  and: print is conditional on match
print: print current line (that contains match)
    F: file to be examined for matches
