Is there a proper way to combine commands for use in the command module? Something like :
Here is a snippet of my code but of coures fails on the command run

# Only necessary for debugging why running of crash failed.

Thanks
The existing release does not use the shell (python subprocess's
shell=True) when running commands. I believe the version in git does,
you may want to try this.

no luck :-( any other thoughts?
Hmm, this seems to work for me. Well, at least commands like;
func "*" call command run "cd /tmp; ls"
func "*" call command run " echo blip >> /tmp/test.foo"; ls /tmp"
Even on non existing command, I just get a shell error for command not found
(all of the above with the git version, btw)
