fast access to any of your favorite directory.

alias pi='`cat ~/.pi | grep ' ; alias addpi='echo "cd `pwd`" >> ~/.pi'
example: -------------------------------------------------------------------------------------------- user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ addpi -------------------------------------------------------------------------------------------- Now that directory is in the list of fast access directories. You can switch to it anytime like this: -------------------------------------------------------------------------------------------- user@ubuntu:~$ pi internal` user@ubuntu:~/workspace/SVN/haystak-repos/trunk/internal/src$ -------------------------------------------------------------------------------------------- Please note the backquote ( the symbol that shares its key with ~ in the keyboard ) pi will switch you to that directory. To see the list of all fast access directories you have to say "cat ~/.pi"

What Others Think

What happens if it finds more than one matching directory?

picardo, the oldest definition gets priority in bash. But usually you will think of some word in your path which is unique enough. So such collisions are rare. But good point.

Are we missing the addpi command?
pkkid · 668 weeks and 2 days ago
crap, nevermind.. its two commands.
pkkid · 668 weeks and 2 days ago
I have to admit--I'm baffled. I see that the grep finds the target directory, but how do we change directory to it? That is, what's the mechanism?
mkc · 668 weeks and 2 days ago
mkc, when you include anything between backquotes ( `like this` ) bash executes it right away. Try saying echo date and echo `date`. This is the hack I am using above to make it change to the directory instead of just printing it out.
senthil · 668 weeks and 1 day ago
looks like pi should be a function rather than an alias, which will remove the need for the backtick. pi () { `grep $1 ~/.pi` } (of course, you have to expand that to three lines -- up to the opening brace on the first, the command on the second, and the close brace on the third).

I think you could accomplish the same thing, in Bash at least, with the $CDPATH environmental variable. Then you'd be able to use the built in cd and completions. You would just have to write a function to add directories to $CDPATH.

In my .bashrc I have: shopt -s cdable_vars export apps="/home/karol/test/apps" Now I just cd apps to go there.
