NOHUP - Yes I get a file called nohup.out and it shows the commands being run/messages which normally appear on the screen while the script is running. But the output from the various programs within the script got to separate directory/files. One of the files doesn't get as much data as when I run it interactively.

Also got this error in the log file after logging off - since I ran it in the background I would have though it would keep going:

Called from GetStats.zPrAll.zPrServer.ServerDiff.DeltaKey.zHash.DeltaKey.Delta::zArray:552
FATAL ERROR: Received signal HUP;
Called from GetStats.zPrAll.zPrServer.ServerDiff.DeltaKey.zHash.DeltaKey.zArray.zFindTotal.(eval).main::zSigHand ler:3027
System call (open) failed; reason=No child processes
System call failed; reason=-1

Here's my steps....
1) Log into UNIX
2) Sudo into my environment
3) Run nohup perf_mon -c revoke.cfg &

If I log out (exit) and close my unix session and shut off my computer will the command still run? If not why not?

Also what does this command do?
nohup perf_mon -c revoke.cfg | tee revoke.out &

Also I'm logged in to work via the internet using VPN. When I lose my connection the session stops. This happens at least once a session (lousy connection). That's why I want to run the script in the background and make sure that the child scripts keep running when I lose my VPN connection.

nohup

NOHUP(1)						    BSD General Commands Manual 						  NOHUP(1)

NAME

     nohup -- invoke a utility immune to hangups

SYNOPSIS

     nohup [--] utility [arguments]

DESCRIPTION

     The nohup utility invokes utility with its arguments and at this time sets the signal SIGHUP to be ignored.  If the standard output is a ter-
     minal, the standard output is appended to the file nohup.out in the current directory.  If standard error is a terminal, it is directed to
     the same place as the standard output.

     Some shells may provide a builtin nohup command which is similar or identical to this utility.  Consult the builtin(1) manual page.

ENVIRONMENT

     The following variables are utilized by nohup:

     HOME  If the output file nohup.out cannot be created in the current directory, the nohup utility uses the directory named by HOME to create
	   the file.

     PATH  Used to locate the requested utility if the name contains no '/' characters.

EXIT STATUS

     The nohup utility exits with one of the following values:

     126     The utility was found, but could not be invoked.

     127     The utility could not be found or an error occurred in nohup.

     Otherwise, the exit status of nohup will be that of utility.

SEE ALSO

     builtin(1), csh(1), signal(3)

STANDARDS

     The nohup utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

BUGS

     Two or more instances of nohup can append to the same file, which makes for a confusing output.
