Nohup with ampersand & process gets disconnected

Operating Systems Linux Red Hat Nohup with ampersand & process gets disconnected
# 8  
Portability: /bin/sh is present on every *X OS. (Well, SCO Unix and an old HP-UX might need the workaround ${1+"$@"} for a historic bug with "$@".)
It works with any compatible shell, too.

This script doesn't actually need bash, so it's better to use the more portable /bin/sh. It can be carried to AIX or whatever without compatibility worries.

Unfortunately, for backwards compatibility reasons /bin/sh on Solaris systems (at least up until Solaris 11) is a pure 1980's Bourne shell. To get a POSIX conforming shell on Solaris systems, their man pages, indirectly, say to use /usr/xpg4/bin/sh.

I tested screen on several servers and it works really well. No problems so far. Thanks.
