I want to check a log file that gets updated very frequently, almost every second. What I want to do from a script is to check this log file
1) for a particular string
2) for a specified time
while it is getting updated. And as soon as it finds that particular string the command should stop.
I got the information from this forum which will satisfy the need 1)
but now I am looking how can a specify time for which the log file should be checked.

Above is the code I used to check the log file for a particular string and exit when it is found. But now I want to specify time for which the log file should be checked and if the string is not found in the specified time then tail stop. Is it possible?

rcsfreeze
RCSFREEZE(1L)RCSFREEZE(1L)NAME
rcsfreeze - freeze a configuration of sources checked in under RCS
SYNOPSIS
rcsfreeze [symbolic revision name]
DESCRIPTION
The rcsfreeze command has the purpose of assigning a symbolic revision number to a set of RCS files, which form a valid configuration.
The idea is to run rcsfreeze each time a new version is checked in. A unique symbolic revision number (C_number, where number is increased
each time rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk.
If the command is invoked with an argument, then this argument is used as the symbolic name to freeze a configuration. The unique identi-
fier is still generated and is listed in the log file but it will not appear as part of the symbolic revision name in the actual RCS files.
A log message is requested from the user which is saved for future references.
The shell script works only on all RCS files at one time. It is important that all changed files are checked in (there are no precautions
against any error in this respect). Run rcsclean(1L) first and see whether any sources remain in the current directory.
FILES
[RCS/]rcsfreeze.version for the version number
[RCS/]rscfreeze.log for the log messages, most recent log message first.
