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'.

Alternatives

There are 2 alternatives - 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.
