Over several years of using Linux distros (Debian happens to be my fave) and BSDs for my primary computing, I've picked up the odd piece of useful info.
ZSH Shell Power
First of all, credit where credit is due. I shamelessly mixed and matched from my Debian files, the ZSH wiki, and various other bits.
ZSH is a shell with incredible autocompletion. Here's a good intro. If you install ZSH, you'll no doubt want to make a test burn. Copy/paste the following files. Make a few changes; then open a terminal or switch to a console (and login as you normally would). Type:
Once you discover that you've been working for the dark side...
You will no doubt rush to type:
But first check /etc/shells to confirm the installation and location of ZSH.
What follows is my regular user's ~/.zshrc.
Modify. Make it your own.
There are only a few differences with my root user's version:
This is all well and good, but it's a bit incomplete without the /etc/zsh/zaliases file:
No doubt you will modify this, but you get the picture. Suffice to say that I not only enjoy using the command line, I barely touch a mouse while doing my work.
When working on consoles I find it annoying to log out and have the work still staring me down. Hence /etc/zsh/zlogout.
And finally, /etc/zsh/zshrc.
There are several other files in /etc/zsh/ which I don't use: zlogin zprofile zshenv
If you are using Debian (and likely, Ubuntu etc.), you will only need to add "zaliases" and modify "zlogout".
You do have another option for the setup of ZSH. Make sure that your user's home directory - regular user, not root - does not have a .zshrc file, and start the shell. It will toss you into a config screen. Also, the first time you run ZSH, don't be frightened by an initial lag. It creates a .zcompdump file and will be nicer the next time.
Hope this is clear. If you choose to use ZSH, enjoy!
