Directories - Contains queued requests for file transfers and command exe-
cutions on remote systems
The /usr/spool/uucp/SystemName directories are the uucp program spooling
directories on the local system. The uucp program creates a SystemName
directory for each system listed in the /usr/adm/uucp/Systems file, includ-
ing the local system.
Each SystemName directory contains queued requests issued by local users
for file transfers to remote systems and for command executions on remote
The uucp program uses several types of administrative files to transfer
data between systems. These files are stored in the SystemName direc-
tories. They are:
Command (C.*) files
Contain directions for the uucico daemon concerning file
Data (D.*) files
Contain data to be sent to remote systems by the uucico daemon.
Execute (X.*) files
Contain instructions for running commands on remote systems.
Temporary (TM.*) files
Contain data files after their transfer to the remote system
until the uucp program can deliver them to their final destina-
tions (usually the /usr/spool/uucppublic directory).
