bash - history sharing between sessions

# .bash_rc
HISTSIZE=9000
HISTFILESIZE=$HISTSIZE
HISTCONTROL=ignorespace:ignoredups

history() {
  _bash_history_sync
  builtin history "$@"
}

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

PROMPT_COMMAND=_bash_history_sync


history() overrides the original function to make sure that the history is synchronised before it is printed, so the numbers match.

In the ".bashrc" file, you can add...

Shortcut for "ls -l":
alias ll="ls -l"

Shortcut for a fast maven clean build:
alias mvnci="mvn clean install -DskipTests -Dcheckstyle.skip=true"

Modify the prompt:
export PS1="\n\u@\h \w\n$ "

Always activate the color in grep:
export GREP_OPTIONS="--color"

Add magic to the space !cmd ...
bind Space:magic-space

Result:

__________________________.bashrc __________________________
# .bashrc
HISTTIMEFORMAT="%d/%m/%y %T "

export GREP_OPTIONS="--color"
alias ll='ls -l'
alias mvnci="mvn clean install -DskipTests -Dcheckstyle.skip=true"

bind Space:magic-space
