Store data files during transfers to remote systems.
The Basic Networking Utilities (BNU) 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 BNU program places the file in a subdirectory of the BNU spooling directory named /var/spool/uucp/SystemName. The SystemName directory is named for the computer transmitting the file. The BNU program creates a temporary data file to hold the original data file.
The full path name of the temporary data file is a form of the following:
/var/spool/uucp/SystemName/TM.xxPID.000
where the SystemName directory is named for the computer 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.
The uucico daemon normally deletes all temporary files when they are no longer needed. However, temporary files can also be removed using the uucleanup command with the -T flag.
These files are part of the Basic Networking Utilities Program (BNU) in BOS Extensions 1.
