Delete Bash History

History of bash sessions are stored in the RAM and written back to ~/.bash_history when the user logs out of the bash session.

To delete the bash history:

1. Delete the .bash_history file:

rm -rf ~/.bash_history

2. Clear the current history stored in RAM:

history -c

Stop logging the bash histories

● Turn off bash history for all users
Append “unset HISTFILE” to /etc/profile:

echo "unset HISTFILE" >> /etc/profile

● Turn off bash history for a specific user
Append “unset HISTFILE” to /home/USER/.bash_profile:

echo "unset HISTFILE" >> /home/USER/.bash_profile
