I tried out zsh, but it had too many buggy display bits for my tastes. After spending too much time researching the issues zsh and I called it quits for now.

I’ve stuck with bash and build a fairly solid config that works for the way I work.

A great book for learning bash is the O’Reily Learning the bash shell

FILES
       /bin/bash
           The bash executable
       /etc/profile
           The systemwide initialization file, executed for login shells
       ~/.bash_profile
           The personal initialization file, executed for login shells
       ~/.bashrc
           The individual per-interactive-shell startup file
       ~/.bash_logout
           The individual login shell cleanup file, executed when a login shell exits
       ~/.inputrc
           Individual readline initialization file

.bashrc

Historical Matching

This is one of my favorites:

if [[ $- == *i* ]]
then
  bind '"\e[A": history-search-backward'
  bind '"\e[B": history-search-forward'
fi
      

It matches what you’ve typed in the shell with historical lines.

example:

$ sudo nmap <Up arrow &uarr;> 
results in 
$ sudo nmap -p22 -Pn 192.168.1.1-254 | grep -B5 Raspberry

.bash_profile

.aliases

Keep the local stuff in ~/.aliases for a machine

I’ve been playing around with a script that replaces all of the . files with files stored in a git repo.

Super handy for deploying new personal systems.
