UUCP Administrative Files

The UUCP administrative files are described next. These files are created in spool directories to lock devices, hold temporary data, or keep information about remote transfers or executions.

Table 26–6 UUCP Lock Files

File Name 



sys represents the name of the computer that is using the file

dev represents the name of a device that is using the file


LOG represents a locked UUCP log file

These files can remain in the spool directory if the communications link is unexpectedly dropped, such as when a computer crashes. The lock file is ignored (removed) after the parent process is no longer active. The lock file contains the process ID of the process that created the lock.
