Hello
in bash shell, what's "$_" variable? where defines it?
Thanks.
It's the last argument of the last command.
I use it often when installing a package.
Something like:
$ apt-cache show "package-name"
[... read the description ...]
$ sudo apt-get install $_
By the way you can also use Alt-. to yank (paste) the last argument.
Keep pressing Alt-. to go through previous arguments.
Best,
