Bash shortcuts in Linux ESC and dot

[@SO-dl2pv]

Great tip! thank you for sharing that. I used to use the variable $_ or !$ but that was tedious to type.

[@neelojp8460]

thanks @SO-dl2pv, $_ was new for me! $_ is a special variable that holds the last argument of the last command executed in the shell.

[@theurbanpenguin]

The variables are good, but also ESC and DOT allows you to cycle though arguments

I have been working with Linux since 1989 and I am still learning new commands, and short cuts, not to mention different utils. Thank you for all you do for the community it is greatly appreciated.

In this case I like to use brace expansion : cp /etc/chrony/chrony.conf{,.old}

[@theurbanpenguin]

yep, until you need to run another command such as the cp and then the edit

[@DevilDriver665]

great one, I'm using esc + . on a daily basis, very useful those little cli tricks ;-) ..... also alt + d for deleting whole words is also very nice, quickly change from systemctrl stop to start for example

[@theurbanpenguin]

Exactly

[@nsonnson]

Is this the same with alt + dot ?

[@theurbanpenguin]

Not on my system

[@DJTomEGun]

I learn a new trick every day!
