Setting environment variables

[polikuo]

What is the best way to set environment variables for an extension ?
Is there an official way ? 

I have some ideas:
  1. Modify ~/.ashrc    with "tce.installed/script"
  2. Modify ~/.profile   with "tce.installed/script"
  3. Add a file into directory /etc/profile.d
      (Must be named as "*.sh", see http://forum.tinycorelinux.net/index.php/topic,5086.msg27095.html)

If one choose to modify "~/.ashrc:~/.profile" with "tce.installed/script"
I can come up 2 ways:
  -- echo lines to the files: echo export FOO=\"Hello World\" >> ~/.ashrc
  -- create config files and source it: echo source /path/to/config/files >> ~/.ashrc

Generally speaking, the benefit of modifying "~/.ashrc:~/.profile" is that the user can use it right away.
However, users might have change their setting, it's not easy to avoid messing up these settings.

On the other hand, by adding a file into directory /etc/profile.d,
the modification would be system wide, but requires a user to log out and log back in.

Any ideas ?

An extension shouldn't modify ~/.profile or ~/.ashrc, unless it's a private one and you know it won't mangle anything. /etc/profile.d is the way.

How are environmental variables in Tinycore permanently set? I haven't found this. Direct editing of /etc/profile.d doesn't work; not being in /home/or /opt), it isn't backed up to my USB. I am trying to correct for the wrong search of ALSA's alias.config, and that can be done with an environmental variable ALSA_CONFIG_... Thanks!

Hi beginners++luck
Welcome to the forum.

... Direct editing of /etc/profile.d doesn't work; not being in /home/or /opt), it isn't backed up to my USB. ...

You can add it to your backup:

Code: [Select]

echo etc/profile.d >> /opt/.filetool.lst
filetool -b
