I thought at first that it might be the infamous MSDOS CRs at the
ends of the lines, but the hex dump proves otherwise. The link
/bin/sh exists, and has correct permissons, as does the file
/bin/bash. It even runs.
Can anyone lend me a clue? I have't got any.
shot in the dark. Are you running this from your home directory which is
mounted via nfs and has the noexec flag set ?
I have exactly one machine. I untarred the tarball from the repo, and
burned the files onto CDROM. The lcc website states that it is
specifically intended to be used this way. I mounted the CDROM, and
made it my working directory. The script is on the CDROM.
However, /bin/sh is on this machine, and it appears that /bin/sh is
specifically what env is having troubles with. And I can run it
directly, just not from the script.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
