I'm confused. People seem to be ignoring the tail -f flag in the pipelines in this code. Note that the command:
will run forever. No command following this in your script will ever be executed.
If you want to took at the current contents of the log (instead of looking at the current and future contents of the log), use:
With tail -f, you don't need (or want) a while true loop, but you need to combine all of the tail and awk pipelines into a single pipeline (not in a loop).

Hi All,

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
