z keeps track of where you’ve been, and how much time you spend there. Source it into your
.bashrc, and then you can say
z foo to jump to the most used directory that has the substring (actually regex)
foo in it, or
z foo bar for the directory that has both
It tab completes out of its file ($HOME/.z), and tries a case sensitive match first, then tries to match without case sensitivity.
z by itself (or
z -l) displays the current list of directories being remembered.
z is not intended as a substitute for the
cd command. You should still
cd everywhere as you normally would. When you want to jump somewhere you have been, then type
z substring to jump a directory in your often used list.
Like many other shell programs, passing an argument of
z will force all further arguments to be treated as search terms. So
z -- -h will match directories that contain
Short answer: instead of running the script as z.sh you type
source z.sh or
. z.sh in a shell, or to make it available all the time, put a command in your
.bashrc that sources it, or just paste the contents of
z.sh directly into your
Long answer: sourcing is like importing. When you run a script in a shell, it creates a subshell, runs your script, and returns to your current shell. If you
cd in that subshell, it won’t matter to your current shell, because when your script is done running, it exits, and comes back to where you (still) are in your current shell. What we want in this case is to have the function and commands in our script defined in our current shell. Sourcing – rather than executing – the file does exactly that.
By default, OSX doesn’t source
~/.bashrc. It will, however, source
~/.bash_profile. One solution is to follow the install instruction, but use
~/bash_profile instead of
~/bashrc. Another solution, which the author uses, is to source
~$ cat .bash_profile [ -f "$HOME/.bashrc ] && . $HOME/.bashrc ~$
Zsh has a lot of completion configuration options, some of which don’t play well with
z. Before opening an issue, please try with your
~/.zshrc moved out of the way, if it works then, you can look at your configuration a bit more. In particular, the
completealiases option is known to break tab completion (see issue #72).
