Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

MS-DOS only: Enable variable expansion from inside of FOR loops with !varname!

Usually the MS-DOS cmd.exe processes in the whole FOR loop as one command and expands each var like %varname% in before (except the loop var of course).

This command enables expansion of other vars than only the loop var during the FOR loop. The syntax of the var to expand is then !varname! inside the FOR loop.

Use command

endlocal

to end the setlocal command.

E.g. (only works from batch files, not from commandline directly):

@echo off

setlocal enabledelayedexpansion

FOR %%A IN (*) DO (

set file=%%A

echo !file!

)

endlocal

Hi ozymandias.

That's not a bash command. As the tags shows, this is a MS-DOS batch command.
