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.
I’m surprised to encounter someone who uses a D compiler but doesn’t know much about environment variables or unix shells.
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.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.
