>View and Change bash history

>Always wanted to know what you have been doing via bash? Did you know bash keeps a history of that? Here is a quick way to check it and an easy way to change the history limit.

First open up a terminal by going to Applications > Accessories > Terminal (in Ubuntu) or press Alt + F2 and type in terminal. Now that you have a terminal open, let’s get down to viewing your history.

To view your history via the terminal, type:


This will show the whole list.

To view your history in a editor (to save for later), just type:

history -w ~/history.txt
gedit ~/history.txt

What history -w ~/history.txt does is save the history to a file named history.txt on your home folder (cd ~/). The next command opens up the file for viewing in gedit.

Note: For more information about history be sure to use the man pages by doing:

man 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

As you can see, the limit can be changed.

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