Command line pastebin
I have been frustrated with copying/pasting command line output to pastebin lately. To solve the problem I’ve whipped up a simple script to pastebin stdin. Check it out.

Simple bash locking
I often need to create lock files in my scripts, so crontab doesn’t spawn more than one process. This is a simple bash lock file function I like to use:
function create_lock { LOCK_NAME=$1 if [[ -e "$LOCK_NAME" ]] then OLDPID=`cat $LOCK_NAME` if ps p $OLDPID > /dev/null then return 1 fi rm $LOCK_NAME fi echo $$ > $LOCK_NAME return 0 }create_lock doesn’t handle race conditions, but it is typically good enough for me.

cp
You can avoid the race condition by using “set -o noclobber”. Like this:
if ! (set -o noclobber; echo “$$” > “/tmp/lock”) 2> /dev/null; then
echo “locking failed”
exit 1
fi

cp is discussing.

And there’s also wgetpaste! http://wgetpaste.zlin.dk/ Does pretty much the same, with a bunch of options etc.
