home dir executable (!/bin/sh, chmod+x) shell scripts won't run without "sh <script>"

That typically indicates the path you've specified in the sh-bang does
not exist. Another common problem there is if the shell script was
written out in DOS format.

If you're certain the first line looks proper, and that the path
exists (/bin/sh most certainly should), try:

perl -p -i -e 's/\r\n/\n/' foo.sh

Then see if it works.

It's possible the partition /home is mounted on is mounted with
noexec, but in that case, I'd expect you'd get a "permission denied"
message, rather than "command not found".
