ALT-? Display list of possible completions. On most systems you can also do this by pressing the TAB key a second time, which is much easier. ALT-* Insert all possible completions. This is useful when you want to use more than one possible match.
The prompt changes to indicate that we are performing a reverse incre- mental search. It is “reverse” because we are searching from “now” to some time in the past. Next, we start typing our search text, which in this example is /usr/bin:
(reverse-i-search)`/usr/bin': ls -l /usr/bin > ls-output.txt
Immediately, the search returns its result. Now we can execute the command by pressing ENTER, or we can copy the command to our current command line for further editing by pressing CTRL-J. Let’s copy it. Press CTRL-J:
$ ls -l /usr/bin > ls-output.txt
Our shell prompt returns, and our command line is loaded
CTRL-P Move to the previous history entry. Same action as the up arrow. CTRL-N Move to the next history entry. Same action as the down arrow. ALT-< Move to the beginning (top) of the history list. ALT-> Move to the end (bottom) of the history list; i.e., the current command line. CTRL-R Reverse incremental search. Searches incrementally from the current command line up the history list. ALT-P Reverse search, non-incremental. With this key, type the search string and press ENTER before the search is performed. ALT-N Forward search, non-incremental. CTRL-O Execute the current item in the history list and advance to the next one. This is handy if you are trying to re-execute a sequence of commands in the history list.
