Data - Contains data to be sent to remote systems
/usr/spool/uucp/LocalSystemName/D.SystemNamexxxx###
Data (D.*) files contain the data to be sent to remote
systems by the uucp uucico daemon. The full pathname of a
data file is a form of the following: /usr/spool/uucp/SystemName/D.SystemNamexxxx###
where the SystemName directory and the SystemName portion
of the file name indicate the name of the remote system.
The xxxx### notation is the hexadecimal sequence number of
the Command (C.*) file associated with that data file;
for example, D.venus471afd8.
After a set period of time (specified by the uusched daemon),
the uucico daemon transfers the data file to the
designated system. It places the original data file 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,
and creates a Temporary (TM.*) file to hold the original
data file.
After receiving the entire file, the uucp program takes
one of three actions: If the file was sent with the uucp
command and there were no transfer problems, the program
immediately renames the TM.* file with the appropriate
data filename, such as D.venus471afd8, and sends it to the
specified destination. If the file was sent with the uuto
command, the uucp program also renames the temporary data
file with the appropriate D.* filename. It then places
the data file in the public directory /usr/spool/uucppublic,
where the user receives the data file and handles it
with one of the uupick command options. If there were
transfer problems (such as a failed login or an unavailable
device), the temporary data file remains in the
spooling subdirectory. The uudemon.cleanu command, a
shell script, removes these files automatically at specified
intervals, or they can be removed manually.
