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.

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!

As the other commenters have mentioned, this is part of the shell configuration and outside the scope of the terminal emulator.

You can configure this yourself by adding shopt -s histverify to your bashrc.

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.

[–] [email protected] 2 points 1 month ago (1 children)

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 month ago (2 children)

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

[–] Zachariah 2 points 1 month ago

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

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

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

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

the answer is !371:p and then up!

Wait till you find out about fzf

One option is Atuin which you can also use with a server connection (self-hosted or not) to sync bash history across computers.

It's so much better when other people build the things I need because they actually get done instead of just making due w an inferior alternative. Lol

thank you for making me aware of it.

[–] ikidd 1 points 1 month ago (1 children)

Tell me about it: I have great ideas that I just need other people to bring to fruition so I can use it.

[–] [email protected] 1 points 1 month ago* (last edited 1 month ago)

i'm just as lazy as your average developer. lol

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

Alternatively, use fc 371 to open the command in an editor and take your time figuring out how you might want to change it.

[–] [email protected] 1 points 1 month ago (2 children)

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

Bash is indeed just !12345.

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)

Same behavior for me as OPs

[–] [email protected] 1 points 1 month 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.

[–] [email protected] 5 points 1 month ago* (last edited 1 month ago) (2 children)

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.

ohh now I got it....yes thats it! Thanks!!

[–] [email protected] 1 points 1 month ago

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

[–] [email protected] 0 points 1 month ago (1 children)

Things like that aren't a feature of the terminal emulator, but of the shell. Try to find out which shell you're using on Android, maybe try using that one on desktop too.

basename $0 returns bash in both.
