The p4 logtail command displays the last block(s) of the error log, and the offset for the next block, when available.
Output consists of a series of lines in tagged format. The first line is "... file LOG", followed by multiple blocks of log data. By default, all blocks from the
start_offset are output until the end of the file. The data is returned in blocks of size
blocksize, each of which is tagged with "
... data". The last line is "
... offset next_offset", where
next_offset is the offset in the logfile from which the next block of data may be retrieved.
