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.

How to make it such that, when running command, it automatically does SOME_ENV_VAR=value command? (something cleaner than aliases?) (lemmy.ml)

hello friends,

I am looking for a way to do what I described in the title. When running command command, I dont want to have to type SOME_ENV_VAR=value command every time, especially if there are multiple.

I am sure youre immediately thinking aliases. My issue with aliases is that if I do this for several programs, my .bashrc will get large and messy quickly. I would prefer a way to separate those by program or application, rather than put them all in one file.

Is there a clean way to do this?

You can add a new executable in your ~/.local/bin directory like command_custom that would start SOME_ENV_VAR=value command. Like if you use bash:

#!/usr/bin/bash

SOME_ENV_VAR=value command

Do not forget to chmod +x the file to make it executable.

This way you will have additional command for your user only (no sudo require to create/update those), for system-wise command put it in /usr/local/bin.
