[Novalug] nohup and chaining commands
junk at taiotoshi.org

I experimented with the below, which seems to answer the mail for you,
if you adjust the commands:
>> cat t.sh
touch t && chmod 666 t && cp -p t tt
>> ./t.sh &
Basically, I put the commands into a file. (The shell script worked
without the shebang (#!/bin/sh), but I put it in anyway.) Then, run the
script in background and you should be good to go. Everything runs in
background instead of just the first command, but you get them running
sequentially, which would appear to be what you want.
Hope that helps...
