Nohup Command gets status Stopped
Good Morning
I need your help please, i tried to execute this script using nohup command but it gets in status stopped

Code:
nohup ./SapInterfases.sh > SapInterfases.log &

prodstg02$ jobs
[1] + Stopped(SIGTTOU)            nohup ./SapInterfases.sh > SapInterfases.log &

I check out log:
Code:
$ more SapInterfases.log
Not a terminal

The goal is to execute each command sequentially and not to execute each command manually from the prompt shell
Those comamnds are sent out via Datastage jobs so logs are generaded by the application itself ?

Thanks for your help in advanced

Please wrap all code, files, input & output/errors in CODE tags.
It makes them far easier to read and preserves spaces in case that is important.

If you are planning to run them sequentially, why are they being put into the background, or does the script run your commands sequentially within it?

You may need to redirect your standard error to the file too like this:-
Code:
nohup ./SapInterfases.sh 2>&1 > SapInterfases.log &

The 2>&1 redirects standard error to standard output, which you then capture in a file.

If the command attempts to read from the terminal while in the background, it will be stopped.

nohup does not and cannot prevent it from just reopening /dev/tty if it really wants to.

So, what is this script doing?

The status shown:
Code:
nohup ./SapInterfases.sh > SapInterfases.log &

prodstg02$ jobs
[1] + Stopped(SIGTTOU)            nohup ./SapInterfases.sh > SapInterfases.log &

means that that job is stopped on terminal Output (i.e., writing to a terminal; not reading from a terminal). So Robin's suggestion might work.

If the script had been stopped when it tried to read from a terminal, the jobs output would have been:
Code:
[1] + Stopped(SIGTTIN)            nohup ./SapInterfases.sh > SapInterfases.log &

If Robin's suggestion doesn't work, as Corona688 said, we'll need to see the code to be able to help you figure out what the script is doing that causes it to be stopped.

Nohup ought to have done that already, no?

With a POSIX-conforming nohup utility, yes. But, we haven't been told what OS and shell are being discussed in this thread. Many implementations of csh include (or at least used to include) a built-in nohup that does not meet POSIX requirements.

Sorry i forgot to edit shell which is:
Code:
prodstg02$ more SapInterfases.sh
/archivos/Shells/SapInterfases.sh Ingl01 20150415 3 20150415
/archivos/Shells/SapInterfases.sh Ingl01 20150416 3 20150416
/archivos/Shells/SapInterfases.sh Ingl01 20150417 3 20150417
/archivos/Shells/SapInterfases.sh Ingl01 20150418 3 20150418

Every line takes about 3 hours, so thtats why i decided to put in a nohup to run in one run and not to take idle times to wait to finish and running the next execution manually

This is the information you asked before:

Code:
HP-UX prodstg02 B.11.31 U ia64 0787399713 unlimited-user license
prodstg02$ ps
   PID TTY       TIME COMMAND
 20275 pts/9     0:00 sh
 16671 pts/9     0:00 ps

Thanks for your hel in advanced
