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
