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.

Bash history option (lemmy.ml)

There is a feature in termux (android) history command which when you use !371 to execute the command 371 in the command history it prints that command in the prompt instead of executing it, then you just press enter to execute it. I found it very useful because many times I want to execute a command that is in the history but with some modification, I'm using Konsole in my desktop PC and I couldn't find an option to make such a thing. The only one I found is executing history -p !371, but that just print the command to stdout and not to the prompt itself.

EDIT: the answer is !371:p then up and the command 371 shows up in the prompt. Thanks Schizo!

Add to your .bashrc following lines:

bind '"\C- ":shell-expand-line'
bind '"\C-x":edit-and-execute-command'

Control+Space: Now you can expand variables, aliases, !492 history commands, the tilde without executing the line. Now you can make changes to the command.
Control+x: Opens the current command in an external editor (such as Vi, or whatever is setup for VISUAL or EDITOR variable). Now you can edit the command and if you save the temporary file and exit editor, the modified command will be executed. If you do not save, the unmodified command before launching the editor will be executed.
