How can I recall the argument of the previous bash command?

You can use $_ or !$ to recall the last argument of the previous command.

Also Alt + . can be used to recall the last argument of any of the previous commands.

If the previous command had two arguments, like this

ls a.txt b.txt

and you wanted the first one, you could type

!:1

giving

a.txt

Or if you wanted both, you could type

!:1-2

giving

a.txt b.txt

You can extend this to any number of arguments, eg:

!:10-12

linux bash unix command

!!:n where n is the 0-based position of the argument you want.

For example:

echo 'one' 'two'# "one two"echo !!:2# "two"

The ! prefix is used to access previous commands.
