Your command line is closer at hand and will do just fine as a regex tester. This perl one-liner creates a little loop that you can use to test as many regex combinations as you please or to test small bits of other perl code. It creates a simple read-eval-print (REP) loop:

perl -ne'{ print "==>",eval,"\n" }'

To use:

  1. Enter the above on your command line and hit return. This starts the REP loop.
  2. Enter a perl statement (variable assignment, regex match statement, etc) and hit return. The result will be printed out.
  3. Repeat until you are bored
  4. Hit control-D to end the loop

Note: tested only on Linux. Presumably also works in cywgin-bash. MsWin command lines are a bit funky and I'm not sure how well perl one-liners behave there. Perhaps another monk can fill in.

Best, beth
