Truenas CSH – Delete Entry in History

Today i wanted to delete some lines from my shell history in a TrueNAS jail as i exported some vars with sensible information.

As i do this in bash on a linux system with the command

history -d IndexOfEntry 

i fired this up in the csh and it …. did not work :-(

The history command in csh does not seem to have a index delete function ….

After a quick search on the net someone came up with this:

history -S             # saves the current history
nano ~/.history        # edit the history file with your
                         favourite editor and delete the 
                         appropriate entries
history -c             # clear the history
history -L             # load the edited history

This worked like a charm and the passwords are gone from the history.
