You have 4 commands that are using redirection:
You need to change the order of redirections on all four of them to:
Plz one question, why changing the order of redirection would make a difference? what is the meaning of "2>&1" ? I think that 2>&1 is telling that standard error becomes standard output and logges to the same outer log, meaning log to "logFileA.txt" instead of the 3 inner log files.
I changed the redirection in the four command lines and it is still logging the Error Message to the Outer Log (logFileA.txt). How could I make it to log the Error to the 3 inner log files?
Is this possible? I am attempting to display a new xterm window and tail -f the log file within that new window. I am currently working on a solaris 8 machine if that has any different meaning than the other platforms. As you can see, I am a newbie to this forum and to UNIX. Any help would be... (2 Replies)

nohup
nice(1) General Commands Manual nice(1)Name
nice, nohup - execute a command at a lower priority
Syntax
nice [-number] command [arguments]
nohup command [arguments]
Description
The command executes command with low scheduling priority (Bourne Shell only). If the number argument is present, the priority is incre-
mented (higher numbers mean lower priorities) by that amount up to a limit of 20. The default number is 10.
The super-user may run commands with priority higher than normal by using a negative priority, for example, `--10'.
The command executes command immune to hangup and terminate signals from the controlling terminal. The priority is incremented by 5. The
command should be invoked from the shell with an ampersand (&) in order to prevent it from responding to interrupts by or stealing the
input from the next person who logs in on the same terminal. The syntax of is also different.
Options-number Increments the priority by a specified number up to a limit of 20. The default is 10.
Restrictions
The and commands are particular to If you use then commands executed with an ampersand (&) are automatically immune to hangup signals while
in the background. There is a built-in command which provides immunity from terminate, but it does not redirect output to nohup.out.
The command is built into with a slightly different syntax than described here. The form ``nice +10'' nices to positive nice, and ``nice
-10'' can be used by the superuser to give a process more of the processor.
Diagnostics
The command returns the exit status of the subject command.
Files
nohup.out standard output and standard error file under nohup
