The uucp Temporary (TM.*) files store data files during transfers to remote systems. After a Data (D.*) file is transferred to a remote system by the uucico daemon, the uucp program places it in a subdirectory of the uucp spooling directory named /usr/spool/uucp/SystemName, where the SystemName directory is named for the computer that is transmitting the file. The uucp program creates a temporary data file to hold the original data file.
The full pathname of the temporary data file is in the following format: /usr/spool/uucp/SystemName/TM.xxPID.000
where the SystemName directory is named for the computer that is sending the file, and TM.xxPID.000 is the name of the file; for example, TM.00451.000. The PID variable is the process ID of the job.
