The .bash_history that Never Heard Anything at All

[Lisa Kachold]

Hey SuperTunaMan,

By default, all commands you type in are stored in the history. You can pick
and chose the commands you want to store by putting the option…

export HISTCONTROL=ignorespace

in your ~/.bash_profile file. This will *make sure that bash don’t store any
command beginning with the space character*. So if you want bash to forget
that you typed in ‘ls’, just type in ‘ ls’(<space>ls).

As far as I know, command substitution [backtics] and sub-command setup also
can be torqued (and cause a nice Snort IDS alert) to do this nicely:

Custom variables are available for bash HIST:

Or a separate logfile for each term:

I also suggest a keylogger:
