uucico — transfer files for the uucp system


/usr/lbin/uucp/uucico -r1 -s system [-x debug_level] [-d spool_directory]

/usr/lbin/uucp/uucico [-x debug_level] [-d spool_directory]


The uucp commands, including uucico, are targeted for removal from HP-UX; see the WARNINGS section below.


uucico scans the /var/spool/uucp directories for work files. If such files exist, a connection to a remote system is attempted using the line protocol for the remote system specified in file /etc/uucp/Systems. uucico then executes all requests for work and logs the results.


uucico recognizes the following options:


Start uucico in the MASTER mode. The default is SLAVE mode.

-s system

Do work only for the system specified by system. If there is no work for system on the local spool directory, initiate a connection to system to determine if system has work for the local system. This option must be used if -r1 is specified.

-d spool_directory

Search directory spool_directory instead of the default spool directories (usually /var/spool/uucp/*).

-x debug_level

Use debugging option. debug_level is an integer in the range 1 through 9. More debugging information is given for larger values of debug_level.

uucico is usually started by a local program such as cron, uucp, or uuxqt (see cron(1M), uucp(1), and uuxqt(1M)). Only when debugging should a user initiate uucico directly.

When started by a local program, uucico is considered the MASTER and attempts a connection to a remote system. If uucico is started by a remote system, it is considered to be in SLAVE mode.

For the uucico connection to a remote system to be successful, there must be an entry in the /etc/passwd file on the remote system of the form:



Use of uucp commands, including uucico, is discouraged because they are targeted for removal from HP-UX. Use ftp(1) or rcp(1) instead.


/etc/uucp/Systems /etc/uucp/Permissions /etc/uucp/Devices /etc/uucp/Maxuuxqts /etc/uucp/Maxuuscheds /var/spool/uucp/* /var/spool/locks/LCK* /var/spool/uucppublic/*


uucp(1), uustat(1), uux(1), cron(1M), uusched(1M).
