15. Ignore specific commands from the history using HISTIGNORE

Sometimes you may not want to clutter your history with basic commands such as pwd and ls. Use HISTIGNORE to specify all the commands that you want to ignore from the history. Please note that adding ls to the HISTIGNORE ignores only ls and not ls -l. So, you have to provide the exact command that you would like to ignore from the history.
# export HISTIGNORE="pwd:ls:ls -ltr:"
# pwd
# ls
# ls -ltr
# service httpd stop

# history | tail -3
79 export HISTIGNORE="pwd:ls:ls -ltr:"
80 service httpd stop
81 history
[Note that history did not record pwd, ls and ls -ltr]

HIST_IGNORE_SPACE (-g)
Remove command lines from the history list when the first character on the line is a space, or when one of the expanded aliases contains a leading space. Only normal aliases (not global or suffix aliases) have this behaviour. Note that the command lingers in the internal history until the next command is entered before it vanishes, allowing you to briefly reuse or edit the line. If you want to make it vanish right away without entering another command, type a space and press return.

Code: Select all

echo $0

Code: Select all

this works because the program being run is the shell

I've started a discussion on the mailing list about this isse: http://lists.kde.org/?t=133844952400003&r=1&w=2. It looks like we'll add a hardcoded space to the commands sent to the terminal.
