log file remains empty
Hi

I'm not sure if I'm in the right section of the forum, but I hope someone can help me anyway. I'm logged onto my university server via ssh and execute a perl script. The output should be written into a log file.

I run the script like this:

perl scripts/test.pl scripts/Config.pm > log 2>&1 &

When I run it in my home directory without ssh, it works perfectly and I get the output plus error messages written into the log file. But when I'm logged in on the uni server and run the command, the log file remains empty. Sometimes it doesn't, but most of the times it is the case. When I look at the ongoing processes with the top command, I can see that the programme is running, but why do I have problems getting the output into the log file?

Thanks,

Kat

nislog

nislog(1M)						  System Administration Commands						nislog(1M)

NAME

       nislog - display the contents of the NIS+ transaction log

SYNOPSIS

       /usr/sbin/nislog [-h num | -t num]  [-v] [directory...]

DESCRIPTION

       nislog  displays  the  contents of the NIS+ server transaction log on the standard output. This command can be used to track changes in the
       namespace. The /var/nis/trans.log file contains the transaction log maintained by the NIS+ server. When updates occur, they are	logged	to
       this  file  and	then  propagated  to replicas as log transactions.  When the log is checkpointed, updates that have been propagated to the
       replicas are removed.

       The nislog command can only be run on an NIS+ server by superuser. It displays the log entries for that server only.

       If directory is not specified, the entire log is searched. Otherwise, only those logs entries that correspond to the specified  directories
       are displayed.

OPTIONS

       -h num	       Display num transactions from the ``head'' of the log. If the numeric parameter is  0, only the log header is displayed.

       -t num	       Display	num transactions from the ``tail'' of the log. If the numeric parameter is  0, only the log header is displayed.

       -v	       Verbose mode.

FILES

       /var/nis/trans.log      transaction log
