where commands are logged apart from .bash_history?

I wish I could restrict access to all files where commands are logged. I found these only in .bash_history file located in the home folder. Is there another place?

command-line bash logs

  1. No, by default commands run in bash (without any output) are saved in the user’s ~/.bash_history file only. There are multiple ways to remove lines from this file, e.g.:

    • manually remove line(s):

      # removes line 42
history -d 42
# removes lines which just say “exit”
sed -i '/^exit$/d' ~/.bash_history
# removes lines containing “/path/” anywhere
sed -i '\_/path/_d' ~/.bash_history

    • prepend a space to the command you don’t want to be saved (␣ means space here):

      ␣echo secret password | …

      See this answer.

    • set the HISTIGNORE variable in your ~/.bashrc to not save certain commands:

      # ignores lines beginning with “ls ” and lines which just say “clear”
HISTIGNORE='ls *:clear'
