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?

Is there some reason you just don't export those env vars in $HOME/.bashrc or $HOME/.bash_profile?

export SOME_ENV_VAR=value

If it's every time you run the command, seems like it should be set globally.

Because it's not as maintainable as separating them by application or some other separation. Would not want to fill up my bashrc with single-application specific code.

You could break it out into other files if you really got that much going on. But if you really have hundreds or more env vars, maybe you should re-think using env vars at all.

Hard to give a rec without more detail, so I don't really get it.
