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; }
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'.
Sample Output
{ /root } # tail /var/log/messages
{ /root } # ... # ohh, I need to watch more logfiles
{ /root } # cd <alt+.> # to get last parameter
{ /var/log } # # Ready for action in the files folder

  • QR codes are those funny square 2d bar codes that everyone seems to be pointing their smart phones at. Try the following... qrurl http://xkcd.com Then open qr.*.png in your favorite image viewer. Point your the bar code reader on your smart phone at the code, and you'll shortly be reading xkcd on your phone. URLs are not the only thing that can be encoded by QR codes... short texts (to around 2K) can be encoded this way, although this function doesn't do any URL encoding, so unless you want to do that by hand it won't be useful for that.

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.
