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!

Uh, are you sure your shell you're using is bash and not zsh or something else?

Bash is indeed just !12345.

Same behavior for me

[–] corvus@lemmy.ml 1 points 6 days ago (1 children)

Yeah, it's bash. But !12345 executes the command 12345, but I don't want to execute it, just print it to the prompt.

Does !12345:p do what you want?

Edit: that also makes hitting the up arrow result in whatever command that was, so if you wanted to edit the line or whatever, you could !12345:p, up, then edit and execute.

It doesn't do anything, just prints a blank line.
