Hi to all,

I have the following issue:

I recently installed MATLAB R2018a in my artix linux (runit). I can launch matlab from the location where the launcher is, i.e.,
/usr/local/MATLAB/R2018a/bin, but if i try to launch it from another location i can't. So i tried to append the mentioned directory to PATH with different methods:

i) PATH=$PATH:/usr/local/MATLAB/R2018a/bin
export PATH

If i check with echo PATH it schows the directory, but after reboot the directory is not in PATH anymore.

ii) As the before method failed i edited ~/.bashrc:

export MATLAB_HOME=/usr/local/MATLAB/R2018a/bin
export PATH=$PATH:$MATLAB_HOME

then i source the file.
If i check with echo PATH it schows the directory, but after reboot the directory is not in PATH anymore.

iii) The last method failed too, so i edited ~/.config/shell/profile

the same result as before.

Can anybody tell what i am doing wrong? I am new to artix runit so maybe i made a big mistake. Thanks in advance!

What's your login shell?

You need to put that $PATH expansion into /etc/profile or ~/.bashrc so that it becomes active on boot or login rather than only when you manually do that from the cli.

Thanks for your answer!

When i i get

Finally i solved partially the issue with the help from artix forums. I created a script in /etc/profile.d/ where i put

and now i can launch matlab from terminal, but not from dmenu, where matlab appears but does not launch from there.What could be the issue in the last case?

The system only processes /etc/profile when you open the terminal and get the shell environment.

You need a shell script for matlab that adds that to $PATH before it calls matlab directly.

On my system matlab is at /usr/local/bin/matlab so it could be renamed to /usr/local/bin/matlab.b and a script named /usr/local/bin/matlab could contain
Thus the icon calling matlab would call the script which would set the variables before actually calling matlab.

I am not aware what zsh uses, but on a bash based system the file ~/.bash_profile gets read at login so that equivalent could be used to set that path for your use with matlab and so not need to make the changes I gave above.

Duplicate the entry in ~/.bashrc or its equivalent so it is available for non-login use as well.

I assume you mean dmenu_run?
In any case, it's possible that your PATH export is not (yet) applied globally.
That would require a) putting it in the appropriate file - one that's sourced at login - and b) log out/in.

.zshrc is for zsh what .bashrc is for bash. They are run if an interactive non-login shell starts.

/etc/profile and its fragments in /etc/profile.d/ are common to zsh, bash, ksh, dash, ash, psh, sh, and to all users on the system.
They are run by login shells; some distros provide code to also run them by interactive non-login shells (and provide a flag variable that ensures they are run once).

Hi to all,

I found from matlab forums that in dmenu i have to write in order to launch it from there. So i think that this post can be considered as solved. Thanks to all for your kind help.

You might change default shell to /bin/bash for your user-id inside /etc/passwd. After that .bashrc env parameters will be taken care by your shell(bash).
