Log(4) Kernel Interfaces Manual Log(4) NAME
Log, .Log - Contains the uucp program log files SYNOPSIS
/usr/spool/uucp/.Log DESCRIPTION
The /usr/spool/uucp/.Log directories contain uucp program log files. The uucp program normally places status information about each trans- action in the appropriate log file each time you use the networking utilities facility. All transactions of the uucico and uuxqt daemons are logged in files named for the remote system concerned. The files are stored in a subdirectory of the /usr/spool/uucp/.Log directory named for the daemon involved. Thus, the log files are named with a form of the following: /usr/spool/uucp/.Log/DaemonName/SystemName The uucp and uuto commands call the uucico daemon. The uucico daemon activities for a particular remote system are logged in the System- Name file in the /usr/spool/uucp/.Log/uucico directory on the local system. The uux and uusend commands call the uuxqt daemon. The uuxqt daemon activities for a particular remote system are logged in the SystemName file in the /usr/spool/uucp/.Log/uuxqt directory on the local system. When more than one uucp process is running, however, the system cannot access the standard log file, so it places the status information in a file with a .Log prefix that covers just the single transaction. The uucp program can automatically append the temporary log files to a primary log file. This is called compacting the log files, and is handled by the uudemon.cleanu command, a shell procedure, which combines the log files of the activities of the uucico and uuxqt daemons on a system and stores them in the /usr/spool/uucp/.Old directory. The default is for the uudemon.cleanu command to save log files that are 2 days old. This default can be changed by modifying the appro- priate line in the shell script. If storage space is a problem on a particular system, reduce the number of days that the files are kept in the individual log files. The uulog command can be used to view the uucp program log files.
