палю короче:
export HISTCONTROL=ignoredups:erasedups # no duplicate entries
export HISTSIZE=100000 # big big history
export HISTFILESIZE=100000 # big big history
shopt -s histappend # append to history, don't overwrite it
#Save and reload the history after each command finishes

export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"
