Here is on that I actually don’t use, but want to use it in scripts. It is meant to be used by piping it. It’s simple branch with user interaction. I don’t even know if there is a standard program doing exactly that already.

# usage: yesno [prompt]
# example:
#   yesno && echo yes
#   yesno Continue? && echo yes || echo no
yesno() {
    local prompt
    local answer
    if [[ "${#}" -gt 0 ]]; then
        prompt="${*} "
    fi
    read -rp "${prompt}[y/n]: " answer
    case "${answer}" in
    [Yy0]*) return 0 ;;
    [Nn1]*) return 1 ;;
    *) return 2 ;;
    esac
}

For the newer version of program, that’s why we have the $PATH. You put your program into one of the directories that is in your $PATH variable, then you can access your script or program from any of these like a regular program. Check the directories with echo "$PATH" | tr ':' '\n'

My custom scripts and programs directory is “~/.local/bin”, but it has to be in the $PATH variable too. Every program and script i put there can be run like any other program. You don’t even need an alias for this specific program in example.

I’m not sure what you mean with the question. If you have any alias like alias rm='ls -l' in your .bashrc in example, then you cannot use the original command rm anymore, as it is aliased to something else. I’m speaking about the terminal, when you enter the command. However, if you put a backslash in front of it like \rm in the terminal, then the alias for it is ignored and the original command is executed instead.

Edit: Made a more clear alias example.

Little tip: In case you need to use rm directly, even with the alias in effect, you can put a backslah in front of the command to use its original meaning: \rm filename

A few days ago I posted a one-liner to do the same thing too. It will resolve aliases from your history and expand program paths to its fullpath. I thought you might be interested: https://beehaw.org/post/20584479

type -P $(awk '{print $1}' ~/.bash_history | sort -u) | sort

i also have the chmod one, but mine is named just x:

alias x='chmod +x'

I also have the yt-dlp "$(wl-paste)" one, but its build around a custom script. So sharing it here makes no sense. Its funny how often we do same thing in different ways (extracting or creating archives in example). Often aliases get development into function and then they turn into scripts. For some of the more simple aliases, here a selection:

alias f='fastfetch -l none'
alias vim='nvim'
alias baloo='balooctl6'

Here is mine for EndeavourOS (based on Arch, BTW):

alias update='eos-update --yay'
alias updates='eos-update --yay ;
  flatpak update ; 
  flatpak uninstall --unused ; 
  rustup self update ; 
  rustup update'

And related for uninstalling something:

alias uninstall='yay -Rs'

With how many new Linux users we get recently, I don’t like this joke at all without a disclaimer. Yes yes, its your own fault if you execute commands without knowing what it does. But that should not punish someone by deleting every important personal file on the system.

In case any reader don’t know, rm is a command to delete files and with the option rm -r everything recursively will be searched and deleted on the filesystem. Option -f (here bundled together as -rf) will never prompt for any non existing file. The / here means start from the root directory of you system, which in combination with the recursive option will search down everything, home folder included, and find every file. Normally this is protected todo, but the extra option --no-preserve-root makes sure this command is run with the root / path.

Haha I know its funny. Until someone loses data. Jokes like these are harmful in my opinion.

Nice, the meaning of Life. This would be perfect, if it was 3.69 instead. But we can’t have it all, otherwise there would be no improvement possible and it gets stale.
