Where is lmp_auto
You may have compiled the program, but your system does not know where it is.
You could link lmp_ auto to your bin directory by
ln -s {path to lmp_auto} ~/bin/liggghts
Then you can run liggghts anywhere

Hi Rashid,
Hi Rashid,
the symbolic link isn't created, since there is already a liggghts link there. See the output:
failed to create symbolic link '/usr/bin/liggghts': File exists
To rewrite the link, you can use the -f option and to write into /usr/bin you should probably run this as sudo:
sudo ln -sf /home/mahid/LIGGGHTS-PUBLIC/src/lmp_auto /usr/bin/liggghts
liggghts
Also please try to copy this line, since if you make any mistake it won't work. I just saw some inconsistencies with "LIGGGHTS-PUBLIC" and "LIGGGHTS_PUBLIC".
Cheers,
Josef

Hi Josef
Hi Josef,
I have a similar problem. I have tried to type 1. sudo ln -s /$HOME/LIGGGHTS-PUBLIC/src/lmp_serial /usr/bin/liggghts before
2. gedit ~/.bashrc
3. Added to end -> alias "liggghts=$HOME/LIGGGHTS-PUBLIC/src/lmp_serial"
I would like to change it to "sudo ln -s /$HOME/LIGGGHTS-PUBLIC/src/lmp_auto /usr/bin/liggghts". However, it displayed ln: failed to create symbolic link ' /usr/bin/liggghts': File exists even tho I have tried to replace it as sudo ln -sf and modify the gedit.
Can you please help? thanks
Regards,
Josh

Hi Josef
Hi Josef,
In addition, when I typed the command "liggghts", it returns as bash: /home/z3490628/LIGGGHTS-PUBLIC/src/lmp_serial: No such file or directory. I am confused that even tho I have changed the new path as lmp_auto, it still appears as bash.......lmp_serial.
Regards,
Josh

Run as Root
When I use the same command as Rashid, I am warned not to run as root. How do I run this an non-root/ fix the issue?
