BTW, if you don't mind sharing, if you execute 'which grep' on the command line, what is the result you see?
Well, it was a minimal install, I had to install which
before I could 'which grep'
Answer was the same as the 'whereis grep' in the OP: /usr/bin/grep
Which leads us to:
A quick glance suggests that .install.sh is checking for grep ...
Stupid, stupid, STUPID - I didn't think to do ls -A
in the directory
Now I can see why it failed, not so much that it couldn't find grep but that which
wasn't installed ... aaarrgghhhh!
As soon as which
was installed, it worked.
Thanks guys and especially you ewemoa
