commandlinefu.com is the place to record those command-line gems that you return to again and again.
Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

You may find you need to reload the crond after this to make the change take effect.
e.g.:
if [ -x /sbin/service ]
then
/sbin/service crond reload
else
CRON_PID=`ps -furoot | awk '/[^a-z]cron(d)?$/{print $2}'`
if [ -n "$CRON_PID" ]
then
kill -HUP $CRON_PID

The reason I had CRON_HOUR and CRON_MINS instead of numbers is that I wanted to generate a random time between midnight & 6AM to run the job, which I did with:
CRON_HOUR=`/usr/bin/perl -e 'printf "%02d\n", int(rand(6))'`
CRON_MINS=`/usr/bin/perl -e 'printf "%02d\n", int(rand(60));'`
