Answer by M. Gleria for How to delete history of last 10 commands in shell?

I used a combination of solutions shared in this thread to erase the trace in commands history.First, I verified where is saved commands history with:

echo $HISTFILE

I edited the history with:

vi <pathToFile>

After that, I flush current session history buffer with:

history -r && exit

Next time you enter to this session, the last command that you will see on command history is the last that you left on pathToFile.
