Temporary(4) Kernel Interfaces Manual Temporary(4)
NAME
Temporary - Stores data files during transfers to remote systems
SYNOPSIS
/usr/spool/uucp/SystemName/TM.xxPID.000
DESCRIPTION
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.
FILES
Describes accessible remote systems Contains uucp command, data, and execute files Contain data to be transferred. Contain files that uucp
has transferred
