Pipe the Output into "cd"

Whatever ways from mentioned here you choose it's important to verify,
that VAR you get is not empty

Code:

VAR=
cd $VAR

Will change dir to your home directory, and it's not probably what you want.
Espesially, if this 'cd' followed by some kind of 'rm -rf'

Indeed! That is a MOST excellent point you make, and it should have been made much earlier in the thread

Thanks Valery,

Hehe. Some loooooong time ago, I myself wrote script where variable name in the cd arg was misspelled... and end up without my home directory. :(

So from that time I learn (by hard way !) that cd is easily one of the most dangerous Unix command :)

I suspect many of us have done similar careless/stupid things -- I know I have at least once!

Isn't it amazing how blazingly fast an errant "rm -Rf" will wipe the root filesystem!?!?

I did this once, thinking I was chrooted, but I wasn't.. Luckily I had a very recent backup!

Heh ... could be done w/o xargs, too.

Code:

 cd $( dirname $( locate $1 |head -n 1 ))

Actually prettier, I feel ;}

I agree, cleaner.

I've got a lot of work a head of me to figure out how that works, but it really does work (if you've got a very specific file name) which you type after the locate command.

Rad to the Max!
I can add Tink mentioned before in ~/.bashrc but I hope this gets added to bash permanently one day.
