One of the features that I miss most in Bash is the shared history between terminals that Zsh supports. I was hunting down a solution for this and came across this Stack Overflow answer 1 by user lesmana. This code snippet does the trick:

HISTSIZE=9000
HISTFILESIZE=$HISTSIZE
HISTCONTROL=ignorespace:ignoredups

history() {
  _bash_history_sync
  builtin history "[email protected]"
}

_bash_history_sync() {
  builtin history -a         #1
  HISTFILESIZE=$HISTSIZE     #2
  builtin history -c         #3
  builtin history -r         #4
}

PROMPT_COMMAND="_bash_history_sync;$PROMPT_COMMAND"

This is very hacky—This setting overrides the shell prompt to sync history every time the prompt is loaded. But like all great hacks, it works.

  1. Preserve bash history in multiple terminal windows [return]
