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.

Replace rm, a neat shortcut, with a less permanent method of removal.

Note may require you to install the trash client; "sudo apt-get -y install trash-cli"

ff() { find -maxdepth 3 -type f | grep -i "$1"; }; fd() { find -maxdepth 4 -type d | grep -i "$1"; }
alias irc="screen -D -R -S chatclient irssi"

This command attempts to attach to existing irssi session, if one exists, otherwise creates one.

I use "irc" because I use different irc clients depending on what system I am working on. Consistency is queen.

Sometimes I would like to see hidden files, prefix with a period, but some files or folders I never want to see (and really wish I could just remove all together).

alias md='mkdir -p'; alias rd='rmdir'; mcd () { mkdir "$@" && cd "$_"; }

I realise that this is just a reiteration of another entry (regardless of whether I came up with all this all by myself), but I would like present my additional alias' in context as a method of managing your directories. Rather convenient.

alias ':q'='exit'; alias ':e'='vim';

This was me just succumbing to the habits, but now I rarely use quit or vim directly, so beware! :)
