You know how you’ve been getting a new system up and running, and then you break something and just can’t remember how you got it working the first time?

Well, Linux has a solution for that. Commands you use on the bash shell is stored in history.

To view your history, just type

history

If you want to search for something specific you did, you can use grep. Eg:

history | grep -i some_command

To save your history to a file use :

history -w ~/history.txt

then feel free to open with your favourite text editor.

Bash keeps it’s own history in a file. You can view that file by opening ~./bash_history

Now to change your bash history length, just open up your .bashrc by doing so:

gedit ~/.bashrc

Once open, at the top add

export HISTFILESIZE=3000
