Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

move up through directories faster (set in your /etc/profile or .bash_profile)

Terminal - move up through directories faster (set in your /etc/profile or .bash_profile)

up N

I did not like two things in the submitted commands and fixed it here:

1) If I do cd - afterwards, I want to go back to the directory I've been before

2) If I call up without argument, I expect to go up one level

It is sad, that I need eval (at least in bash), but I think it's safe here.

eval is required, because in bash brace expansion happens before variable substitution, see http://rosettacode.org/wiki/Repeat_a_string#Using_printf


There is 1 alternative - vote for the best!

Terminal - Alternatives
function up { for i in `seq 1 $1`; do cd ../ && pwd; done }

You can also remove the "&& pwd" if you don't want it to print out each directory as it moves up.

function up { i=$1; while [ $((i--)) -gt 0 ]; do cd ../ && pwd; done }

Here's an alternative if you don't have seq.

Know a better way?

If you can do better, submit your command here.

What others think

function up { cd $(eval printf '../'%.0s {1..$1}) && pwd ;}

Thanks, adrruiz!

It actually used a linebreak-ed version in .bashrc so the problem did not occur there.

Comment by michelsberg 196 weeks and 1 day ago

i use this:

function / { cd ..; };

function // { cd ../..; };

function /// { cd ../../..; };
