Alt + . does the same thing as well, with the added advantage that you can keep pressing alt and then hit . several times to go through all the "last arguments" in your history one by one.

Further, holding Alt followed by numeric argument followed by dot, gives you an argument at a specific position. For example, Alt + 1, Alt + . copies the first argument.

Cool one. "Ctrl + R" also does the same thing to search through past commands and then "Tab" to select the command you are looking for.

May favorite bash "trick" is:

!-1:gs/hello/world

which runs the last command with all instances of hello replaced by world. !-1 can be any so called event designator, for instance !n to refer to any specific line number from history or !string for last command containing a particular string.

Seriously people, read the man page for bash. Your shell has so many cool features.

And if you only have a single instance to replace, you can use ^old^new^

$ echo "hello hello hello world" hello hello hello world $ ^hello^bonjour^ echo "bonjour hello hello world" bonjour hello hello world

[ESC + .] and [ALT + .] are most definitely news ones for me. Thank you. Always learn something new here!

Thanks, I discovered C-o thanks to you (even though I have gone through the bash manual several times).

No, more having to press C-r multiple times just to get sequential group of commands from history.
