From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

To use the last argument of the last ran command, use the Alt+. keys.

Sounds like a poor-man's !$ to me!

Fewer keystrokes, more features, and the ability to see what you're about to do explicitly. How does that make it the poor man's option?

Seems like it's terminal-emulator-specific rather than a built-in shell feature

No, it's a shell feature. Terminal emulators don't even know what shell are running typically, and I haven't heard of them adding shell features. That would require the terminal emulator knowing you're using bash, knowing how to interrogate history etc..

From man bash:

       yank-last-arg (M-., M-_)
              Insert  the last argument to the previous command (the last word
              of the previous history entry).  With a numeric argument, behave
              exactly  like  yank-nth-arg.   Successive calls to yank-last-arg
              move back through the history list, inserting the last word  (or
              the  word  specified  by the argument to the first call) of each
              line in turn.  Any numeric argument supplied to these successive
              calls  determines  the direction to move through the history.  A
              negative argument switches the  direction  through  the  history
              (back or forward).  The history expansion facilities are used to
              extract the last word, as if the "!$" history expansion had been
              specified.

Neat! Other replies saying it doesn't work on their machine, I'll have to try it out in a few different environments.
