HISTORY ************************************

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

history -w ~/history.txt
vim ~/history.txt

export HISTTIMEFORMAT="%F %T "
export HISTTIMEFORMAT='%F %T '

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 vim.


You can search through your bash_history by piping your history file into grep like so:

history | grep "search term here"

Execute previous command that starts with a specific word

Type ! followed by the starting few letters of the command that you would like to re-execute. In the following example, typing !ps and enter, executed the previous command starting with ps, which is ‘ps aux | grep yp’.

# !ps
ps aux | grep yp
root     16947  0.0  0.1  36516  1264 ?        Sl   13:10   0:00 ypbind
root     17503  0.0  0.0   4124   740 pts/0    S+   19:19   0:00 grep yp

MOUNT ************************************
sudo mount -t vboxsf WIL /home/user/foldername
