Sometimes, you may have to disable the Linux history, which is not a difficult task. We can do this with the help of the “set” command. Please follow the steps given below.
The set command is an inbuilt bash command, and you can use this command to set or change the bash shell environment.

“set -o” will give you the list of features and the status.

-bash-4.3# set -o
allexport off
braceexpand on
emacs on
errexit off
errtrace off
functrace off
hashall on
histexpand on
history on
ignoreeof off
interactive-comments on
keyword off
monitor on
noclobber off
noexec off
noglob off
nolog off
notify off
nounset off
onecmd off
physical off
pipefail off
posix off
privileged off
verbose off
vi off
xtrace off

As you can see, the “history” status is “on”, which is why it records everything you type. Let’s disable history Linux.
To disable an option, you can use the command given below.

set +o

If you want to enable it later, you can use the command given below.

set -o

In this case, we can go to disable the “history”.

-bash-4.3# set -o | grep history
 history on
-bash-4.3# set +o history
-bash-4.3# set -o | grep history
 history off

See! It’s “Disabled”!

If you want to enable it again, type the following command.

set -o history
