alias not showing up in bash history

HISTIGNORE variable is set to:

export HISTIGNORE="&:ls*:reboot:pwd:exit:clear:[ \t]*"

I have couple of Alias set. One of them is 

alias todo='emacs ~/Dropbox/Documents/todo.txt'

None of them shows up in history. Not that I want them to show up in history, but what baffles me is, why the hell they do not show up in history.

Solution

  • In bash, the sequence \t only means tab inside of $'...'. That's why your pattern matches your todo command; it matches anything that starts with t.

    You can fix it like this:

    tab=$'\t'
export HISTIGNORE="&:ls*:reboot:pwd:exit:clear:[ $tab]*"
unset tab
