# Ubuntu – How to clear bash history completely

bashhistory

I want to clear all previous commands from the history of my server. I used history -c and it seems all things are cleared but when I ssh to the server, all the commands are still there.

How can I clear them permanently?

#### Best Answer

• The file ~/.bash_history holds the history.

To clear the bash history completely on the server, open terminal and type

cat /dev/null > ~/.bash_history


Other alternate way is to link ~/.bash_history to /dev/null

### However,

One annoying side-effect is that the history entries has a copy in the memory and it will flush back to the file when you log out.

To workaround this, use the following command (worked for me):

cat /dev/null > ~/.bash_history && history -c && exit
