qwwad_mesh

Asked by Colin Boyle

I'm trying to run qwwad_mesh and it's throwing a "command not found" error. Other qwwad commands work, so I believe the installation is good. It also appears in /usr/bin along with working qwwad commands.

Hi Colin,

That sounds odd. Is there any chance you have more than one installation? Try running this to see where the other programs are being read from:

which qwwad_ef_generic

which qwwad_mesh

Thanks for the quick reply! I did download the package first following the instructions for non-Ubuntu before realizing that I could run the Ubuntu directions, but I didn't get far enough the first time to install anything (I think, I am a linux novice)

When I ran which qwwad_ef... it returns /usr/bin/...

which qwwad_mesh still tells me command not found

What is the output of

ls -l /usr/bin/qwwad*

The output is a bit long, but the one of the lines is:

-rwxr-xr-x 1 root root 101216 Sep 2 2016 /usr/bin/qwwad_mesh

The other lines list other qwwad extensions, and have different numbers in place of 101216

I've discovered that if I specify usr/bin/qwwad_mesh it runs. I have no idea why that's the case for this extension and none of the others I've tried so far, but I'm going to assume it was something I did during installation and mark the problem as solved.

Thanks for all the help

It sounds like something weird has happened with your PATH. Can you check...

echo $PATH
