Removing history If you want to delete a particular command, enter history -d <line number> . To clear the entire contents of the history file, execute history -c .
How can I remove or delete a single command from bash history file? You can use the history command to clear all history or selected command line.
You can try by opening up browser settings and navigate to privacy. Or, you can tap ctrl+shift+del button simultaneously to purge the history!
You can clear your bash history like this:
history -cw
If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.
However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.
Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:
[client]
user = <username>
password = <password>
Make sure to change the file permissions so that only you can read the file.
Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.
