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.

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.

Smart `cd`.. cd to the file directory if you try to cd to a file

Terminal - Smart `cd`.. cd to the file directory if you try to cd to a file
cd() { if [ -z "$1" ]; then command cd; else if [ -f "$1" ]; then command cd $(dirname "$1"); else command cd "$1"; fi; fi; }

Smart `cd`.. cd to the file directory if you try to cd to a file

This little function will smarten 'cd'. If you try to cd into a file (which I guess we all have done), it cd's into the directory of that file instead.

I had to use nesten if's, to get cd to still work with 'cd' (to get to $HOME), 'cd -' (to get to last directory), and 'cd foo\ bar'.


There is 1 alternative - vote for the best!

Know a better way?

If you can do better, submit your command here.

What others think

Nice, but we can make it tidier...

First, turn the nested if then if to if, elsif, else fi.

Next drop dirname for shell magic: ${1%/*}

Then move all the command cd's to the end

cd() { if [ -z "$1" ]; then D=~; elif [ -f "$1" ]; then D="${1%/*}"; else D="$1"; fi; command cd "$D"; }

Now only 83 chars and everything still works :-)

cd() { [ -z "$1" ] && set -- ~; [ -f "$1" ] && set -- "${1%/*}"; command cd "$1"; }

Even shorter:

cd(){ [ -f "$1" ]&&builtin cd "${1%/*}"||builtin cd "$1";}

Nice (+1) though I probably won't never use it since bash completion don't complete regular file names.
