Linux shell history - Trick

To display the history of commands with date and time -

1. history

2. cat~/.bash_history

3. history number_of_command_to_display
   Like this "history 2" - will display first and second command

To clear the history:
rm ~/.bash_history && history -c

To execute the 10 th command in the history, just type - "!10"

Using grep to find the specific command

To save the history in a file
history > list.txt

Some command needs root permission..

Good day
