You need to use the history command to display or manipulate the history list on a Linux or Unix-like systems. This command displays the list of commands previously typed with line numbers, prefixing each modified entry with a *.
The bash shell supports a history expansion feature that is similar to the history expansion in csh.
Display list of previously typed commands
Simply type the following command:
history history 10 history | less history | grep 'command-name-here'
How do I reissue a long command without retyping it?
To reissue a command in bash/csh/tcsh/zsh shell, type ! the exclamation point followed by the number of the command you would like to run or repeat. For example, if you would like to reissue command ‘ssh firstname.lastname@example.org’ from the above output i.e. command # 80, type:
Scrolling through the command line history
You can also scroll through the command line history simply by using the [up] and [down] arrow keys too.

To repeat the same last command again, just type !!:
Or you can also refer to the previous command using:
To repeat to the most recent command starting with word ‘ssh’ type:
