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.

What's the best way to have a .bashrc that I can use throughout systems? (lemmy.ml)

So, I just found out about a programme called SynthShell which kind of does the work for you and gives you a nice looking shell, the thing is that this also creates some config files and other stuff in my system, instead of just one .bashrc file to edit. What would be the best way to learn to have a nice looking bash where I can just have a backup of it that I can use throughout systems?

You'll want to look into a category of programs called dotfiles managers. There's a bunch of them. Most of them are based on some kind of version control system, usually git.

I personally use yadm

I personally use yadm

I just use some code and Git.

if [ ! -z "$PS1" ]; then
    repo="${XDG_CONFIG_HOME}/dotfiles/"
    br='origin/main'

    title="\e[1m\e[31m\n ░▒▓\e[7m    %s    \e[27m▓▒░\e[0m\n\n%s\n\n"
    status="$(git --git-dir="$repo" --work-tree="$HOME" status -s)"
    diff=$(git --git-dir="$repo" --work-tree="$HOME" diff --stat --cached $br)

    [ -n "$status" ] && printf "$title" "Uncommited changes!" "$status"
    [ -n "$diff" ] && printf "$title" "Not yet pushed commits!" "$diff"

    unset title status diff br
    alias dotfiles="/usr/bin/git --git-dir=$repo --work-tree=$HOME"
fi

The code runs when it's an interactive shell with a PS1 prompt and just checks if any of the tracked files have changed or if there are commits that are not pushed. By configuration I ignore all untracked files. If something has changed or wasn't pushed it always prints an annoying message.

Whenever I want to do something I use dotfiles ..... instead of git ....., everything else works the same.

This is the fun way. I have a ton of configuration files in git and I symlink to them from various places with an install script. And zshrc has enough brains to determine the OS it's running under and the hostname. Between those two, I can have it do all the Right Things no matter what system it's on. So far, it deploys to my personal Mac, my work Mac, my personal Linux box, my SDF account, and my Android phone with tmux.

Basically I clone the repo into .local/share/beejsys and then run the install script and everything just works. And I don't typically have to rerun the install script after a pull.

Do I understand correctly you use the install script for files outside home dir? If so could you share this as I’m running into that issue.

[–] beejjorgensen@lemmy.sdf.org 1 points 10 months ago

No, they're inside my home directory, alas.
