Repeat command

[Gedeon]

Be carefull whith loop commands, if you don't have pause in this sequence, the CPU time may be used at 100%.

A loop like : while true; do :; done ==> 100% and very difficult to stop this by ctrl-c.
You must use pause with sleep N (N can be < 1 like 0.2).

This will not repeat the command continously. It will just allow you to get a list of the last commands to execute it again - but manually.
You can also use the history command and execute a specific command using ! followed by the number.
And Ctrl+r can search a part of the last entered commands.
