   Hi,

   I didn't know about this, so I tried:

bash-5.1$ nohup ./darwin64-fpctrunkup.sh < /dev/null > ~/logs/trunk/all.log 2>&1 &
[1] 26839
bash-5.1$
[1]+  Exit 127                nohup ./darwin64-fpctrunkup.sh < /dev/null > ~/logs/trunk/all.log 2>&1
bash-5.1$ cat nohup.out
cat: nohup.out: No such file or directory
bash-5.1$ cat ~/logs/trunk/all.log
nohup: can't detach from console: Inappropriate ioctl for device

   It still does not work as it is on other systems...
