Stay in the loop…

Follow the Tweets.

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.

if you cd into a directory then cd into another directory somewhere else then you run the cd - command you will go to the previous directory you was in!! To go back to the other directory just run it again. So if you are working in 2 different directories then this is the perfect command for you.

nc -w 5 -v -l -p 80 < file.ext
find -maxdepth 1 -type d | while read dir; do echo $dir; echo cmd2; done
curl -u user:pass -d status=?I am Tweeting from the shell? http://twitter.com/statuses/update.xml

I know how hard it is to find an old command running through all the files because you couldn't remember for your life what it was. Heres the solution!! Grep the history for it. depending on how old the command you can head or tail or if you wanted to search all because you cannot think how long ago it was then miss out the middle part of the command. This is a very easy and effective way to find that command you are looking for.
