Are the files, like a.log, always 100 lines?
Have you tried anything yet, like using the wc command to find the number of lines in a file? Please show us so we can help.

NAME
uulog - Displays UUCP log files SYNOPSIS
/usr/lib/uucp/uulog -f system [-number] uulog uulog systems [-number] uulog -s system [-number] uulog -x [systems] The uulog command displays the contents of a log file of uucico or uuxqt activities. STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: uulog: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
[Tru64 UNIX] Performs a tail -f on the file transfer log for the specified system, displaying the end of the log file. Use the Interrupt key sequence to leave the file and return to the prompt. Prints information about copy requests involving the specific system. If no sys- tem is specified, information is displayed for all systems. Note: System name can contain only ASCII characters. [Tru64 UNIX] Displays the uuxqt log file for the specified systems. If no systems are specified, information is displayed for all systems. [Tru64 UNIX] Displays the last lines of the log file. The number of lines is determined by the number argument. (To display the lines, the uulog command issues a tail for the specified number of lines.) DESCRIPTION
Individual log files are created for each remote system with which the local system communicates using the uucp, uusend, uuto, or uux com- mands. Use the uulog command to display a summary of uucp, uusend, uuto, and uux command requests by a system or systems. All of these transac- tions are logged in files under the /usr/spool/uucp/.Log/ directory. The files are named daemon_name/system, where the daemon_name direc- tory is named for the daemon involved and the system file is named for the remote system the daemon is contacting. The uucp and uuto commands call the uucico daemon. The uucico activities are logged in the system file in the /usr/spool/uucp/.Log/uucico directory. The uux and uusend commands call the uuxqt daemon. The uuxqt activities are logged in the /usr/spool/uucp/.Log/uuxqt/system file. You can examine these individual log files by issuing the uulog command directly. However, you can also have these temporary log files appended to a primary log file that you can then examine. This is called compacting the log files and is handled by uudemon.cleanu, a shell script in /usr/lib/uucp. NOTES
The uulog utility is marked LEGACY in XCU Issue 5. EXAMPLES
To display the uucico log file for system hera, enter: uulog -s hera [Tru64 UNIX] To display the uuxqt log file, enter: uulog -x [Tru64 UNIX] To display the last forty lines of the file transfer log for system zeus, enter: uulog -f zeus -40 To display the uucico log file for systems pluto and venus, enter: uulog pluto venus [Tru64 UNIX] To display the uuxqt log file for systems pluto and venus, enter: uulog -x pluto venus FILES
Contains log files. Public directory. SEE ALSO
