How to remove PAESSHSTART and PAESSHEND from history

To complete the proposed workaround (which worked for me with centos/bash) :

1- first, just let PRTG flood the user's bash history with PAESSHSTART...PAESSHEND entries

2- then, run in the user's command line the following : ##Back up the .bashrc file ;-) cp $HOME/.bashrc $HOME/.bashrc.`date '+%Y%m%d'`;

##add HISTIGNORE to the .bashrc file with this single line command (run it only ONE time) : grep "PAESS" $HOME/.bash_history | sort | uniq > /tmp/histignore.list && echo export HISTIGNORE=\"`sed '{:q;N;s/\n/:/g;t q}' /tmp/histignore.list `\" >> $HOME/.bashrc;

3- edit the user's .bashrc file and verify you don't have more than one declaration of HISTIGNORE... else, just merge all the existing values into a single one HISTIGNORE="...".

'hope that will work for you, best regards.
