Command line history

The history command can be used to list all the previous commands you have typed before. The syntax is as following:

history n

where n is the number of commands you have typed before.

Example:
This lists the last 5 commands typed before:

$ history 5
  510  cp /home/pepito/myfile /home/pepito/myfolder
  511  ls
  512  ip addr show
  513  ifconfig
  514  history 5

You can select to execute a command from the list with the following:

!n

Where n is the number of the command in the list.

Example:
This will execute the command number 511 that is the ls command:

$ !511
ls
