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!

i have a need for something like this too; but i've been making due with crtl+r and that's been good enough to prevent me from taking action on it.

I didn't know that, it's not what I was asking but it's a cool command, thanks.

Wait till you find out about fzf

careful with it; i need the thing that you asked for too and crtl+r has been effective enough to prevent me to creating it.

[–] [email protected] 1 points 1 day ago (3 children)

but can you modify the command? I tried but I couldn't.

[–] [email protected] 2 points 1 day ago

For CTRL+R, once you see the command you want, hit ESC, and the command is there ready to edit.

idk if you're having the same issue but unborking my $PS1 fixed this for me. left right arrow keys should let you edit the command.

[–] [email protected] 1 points 1 day ago (1 children)

yes. use the arrow keys to modify it before hitting enter

the answer is !371:p and then up!
