I’ve set some path variables on my Raspberry Pi, but since I upgraded the D compiler version, I need to change it, by removing the reference to the old version, as the two would collide with each other. The issue is, I used some now obscure tutorial, which I no longer can find, and it’s not found in the usual culprit /etc/profile, yet the path is still listed with an echo $PATH.
I need to get the list of bootup scripts where it was added (it was added with something like that if I remember correctly), or somehow reset it without reinstalling the Linux to my Pi. I’ll give my paths a more generic names in the future, so I can just rename a folder, then use the compiler right out of the box without having to mess around with the path yet again.
You must log in or # to comment.
I’m surprised to encounter someone who uses a D compiler but doesn’t know much about environment variables or unix shells.
Due to the nonexistent documentation for the issue,
Are you familiar with the
mancommand, for reading the system’s manual pages? When you get some time, you might want to runman bashand read whatever sections are relevant to things you want to do, such as where the Invocation section talks about startup files.I’ll give my paths a more generic names in the future, so I can just rename a folder, then use the compiler right out of the box without having to mess around with the path yet again.
Creating a symlink (symbolic link) with a generic name to point at the version-specific directory name is a common way to do this. (For example,
ln -s dmd-2.107.1 dmd) You could then add the symlink’s path to your PATH environment variable, and replace the symlink whenever you want to point it at a different compiler version. Runman lnfor more info.I also suggest finding a beginner’s guide to linux (or unix) when you get a chance. This stuff gets a lot easier once you learn the basics.
I use LDC2 on the Pi, since that’s my only option there.
Found it in
.bashrc, editing it makes my pi no longer wanting to log in to GUI. Ctrl+Alt+F1 still works. Commenting out theexport PATHpart does not fix it. Some forums recommended deleting some files, so I’ll try doing that.UPDATE: Due to the nonexistent documentation for the issue, I had to reinstall the OS for my Raspberry Pi, and I really don’t like Wayland, nor the fact it forced the Hungarian Keyboard layout onto me (near unusable for programming, because at IBM, people wanted their menu key)…
People are really still complaining about Wayland? I thought that was just a meme
Issue is, a lot of applications still haven’t fully moved to Wayland, especially Barrier, which I use to share a keyboard and mouse from my Windows PC.
You can set the initial value directly in
/etc/environment, did you check that? It could also be set only for your user, so it might be in~/.profile,~/.bashrcor ~/.bash_profile` (or the rc file for your shell if you’re not using the default bash).Edit: I suppose you could also have added a startup script in
/etc/init/or/etc/init.d/, or in/etc/rc.local
