Delete a Command from Bash History
Here I give some test commands to fill history:
pontikis@ubuntu:~$ clear pontikis@ubuntu:~$ echo 1 1 pontikis@ubuntu:~$ echo 2 2 pontikis@ubuntu:~$ echo 3 3 pontikis@ubuntu:~$ my-secret-command my-secret-command: command not found
I can view the history using history
command:
pontikis@ubuntu:~$ history 1 clear 2 echo 1 3 echo 2 4 echo 3 5 my-secret-command 6 history
So, to remove my-secret-command
(line 5), I use
-d
option of history
command:
pontikis@ubuntu:~$ history -d 5 pontikis@ubuntu:~$ history 1 clear 2 echo 1 3 echo 2 4 echo 3 5 history 6 history -d 5 7 history
DO NOT KEEP a Command in Bash History
Start a command with SPACE if you DO NOT want to be included in Bash history:
pontikis@ubuntu:~$ my-secret-starts-with-space my-secret-starts-with-space: command not found pontikis@ubuntu:~$ history 1 clear 2 echo 1 3 echo 2 4 echo 3 5 history 6 history -d 5 7 history
Make sure that your .bashrc file contains something like this
# don't put duplicate lines or lines starting with space in the history. # See bash(1) for more options HISTCONTROL=ignoreboth
In other words, ensure that HISTCONTROL environmental variable is set to ignorespace or ignoreboth
