I'm attempting to install this and running into issues. I am supposed to add a line to the ".bashrc" file? Where in the file? the bottom? the top? somewhere in the if statement? do I make it an alias?

Link to z site:

Here's my .bashrc:

echo ". ~/" > ~/.bashrc

Just put it anywhere. the end will do. – Hasturkun May 16 '13 at 16:25 is in my / directory --- .bashrc is in my /etc/ directory --- at the end of my .bashrc, I added: . ~/ --- I get: -bash: z: command not found – Samuel Stiles May 16 '13 at 16:28
Add it to your ~/.bashrc, and use an absolute path. Also, this won't affect a running shell. though you could run . ~/ in one for that. – Hasturkun May 16 '13 at 16:29
I don't have a ~/.bashrc --- should I just drag it from /etc/ into /? --- and what's an absolute path? – Samuel Stiles May 16 '13 at 16:31
If you don't have one, create one. An absolute path is of the form /home/user/ or similar. – Hasturkun May 16 '13 at 16:33

Back up a second. /etc/bash.bashrc is the system-wide settings file for bash. $HOME/.bashrc (often abbreviated as ~/.bashrc) has your user's personal settings. ~/.bashrc is read everytime you start a new shell (open a terminal) and so is /etc/bash.bashrc, you don't need to copy anything from one to the other, both will be read.

So, if your system has no ~/.bashrc, all you need to do is create one and add the relevant line to it:

echo ". ~/" >> ~/.bashrc

That's it.

The . is an alias to bash's source:

source: source filename [arguments]
    Execute commands from a file in the current shell.

    Read and execute commands from FILENAME in the current shell.

I created ".bashrc" in my /home directory --- it's contents can be seen in my post (edited above) --- is also located in my home directory --- I still get -bash: z: command not found – Samuel Stiles May 16 '13 at 16:49
@SamuelStiles /home is not your home directory, /home/your_username is. Both .bashrc and should be in your /home/your_username directory. Just run this command: cp /home/.bashrc /home/ $HOME. – terdon May 16 '13 at 16:51
done.... stil getting -bash: z: command not found :S I'm logged in as root, will that muck with things? – Samuel Stiles May 16 '13 at 16:55
Correction: I had to re-open my terminal window. It now appears to be working! Thank you! – Samuel Stiles May 16 '13 at 16:59
@SamuelStiles yes, .bashrc is read every time bash is started so you need to restart bash (open a terminal) for it to be read. If my answer helped you please mark it as accepted. – terdon May 16 '13 at 17:00
