find_terminal_command_in_history.py

"""
Description: find terminal command in bash history

Purpose created: I had run several files using the word 'cfdg' in the command.
This was several months ago. I wanted to retrieve all lines in my bash history 
where that command was used.

If used remember to change the user to your name.
This script will create a file 'using-(whatever search term used).txt'
in this case using-cfdg.txt. The first line of the print will be the filename generated
again in this case it will print- FILENAME IS :  using-cfdg.txt
then it will start printing the history line by line pausing slightly because of the sleep(.5)
At at time this may be run, even with the same search term. The old file will be replaced
and updated if the search term is reused.

Example: I wanted to find every occurance of docker used in a terminal command. 
Just enter docker in the input box. 

My return was.

FILENAME IS :  using-docker.txt

gedit jack-install-docker.html
sudo nano /etc/apt/sources.list.d/docker.list
sudo apt-get purge lxc-docker
apt-cache policy docker-engine
sudo apt-get install docker-engine
