Reports the status of and provides limited control over BNU operations.
uustat [ [ -n Number ]
[ -a | -k JobID | -m | -p | -q | -r JobID ] | [ -s System ] [ -u User ] ]
The uustat command is a Basic Networking Utilities (BNU) command that displays status information about several types of BNU operations. It is particularly useful in monitoring the status of BNU requests.
In addition, the uustat command also gives a user limited control over BNU jobs queued to run on remote systems. By issuing the command with the appropriate flag, a user can check the general status of BNU connections to other systems and cancel copy requests made with the uucp and uuto commands.
If the uustat command is issued without any flags, the command reports the status of all BNU requests issued by the current user since the last time the holding queue was cleaned up. Such status reports are displayed in the following format:
jobid date/time status system_name user_ID size file
There are two types of BNU queues:
After the time has elapsed, the entries in the holding queue are deleted either manually with the BNU uucleanup command or automatically by commands such as uudemon.cleanu started by the cron daemon.
When sending files to a system that has not been contacted recently, it is a good idea to use the uustat command to see when the last access occurred; the remote system may be down or out of service.
The following flags are mutually
exclusive. Use only one at a time with the uustat
|-a||Displays information about all the jobs in the holding queue, regardless of the user who issued the original BNU command.|
|-kJobID||Cancels the BNU process specified by the JobID
variable. The person using this flag must either be the one who made
the uucp request now being canceled or be
operating with root authority.
This flag cancels a process only when that job is still on the local computer. Once BNU has moved the job to a remote system for execution, the -k JobID flag cannot be used to cancel the remote job.
|-m||Reports the status of the most recent attempt to contact the specified system with a BNU command. If the BNU request was completed, the status report is successful. If the job was not completed, the status report is an error message saying that the login failed.|
|-n Number||Allows the user to specify the amount of machines from which to collect BNU status information. The amount specified should be greater than or equal to the amount of machines in the Systems file. The default is 200.|
|-p||Runs a ps -flp (process status: full, long list of specified process IDs) for all PID numbers in the lock files.|
|-q||Lists the jobs currently queued to run on each system. These jobs
are either waiting to execute or in the process of executing. If a
status file exists for the system, its date, time, and status information are
reported. Once the job is finished, BNU removes that job listing from
the current queue.
In a status report, a number in parentheses next to the number of a C.* (command) file or an X.* (execute) file represents the age in days of the oldest C.* or X.* file for that system. The retry field represents the number of times BNU tried and failed to execute the command because of, for example, a failed login, locked files, or an unavailable device.
|-rJobID||Marks the files in the holding queue specified by the JobID
variable with the current date and time. Use this flag to ensure that a
cleanup operation does not delete files until the job's modification time
reaches the end of the specified period.
You can use either one or both of the following flags with the uustat command:
|-s System||Reports the status of BNU requests for the workstation specified by the System variable. The System name can contain only ASCII characters.|
|-u User||Reports the status of BNU requests by the user specified by the User variable, for any workstation. The User name can contain only ASCII characters.|

|1||Job ID of the operation|
|2||Date and time the BNU command was issued|
|3||An S or an R, depending on whether the job is to send or receive a file|
|4||Name of the system on which the command was entered|
|5||User ID of the person who issued the command|
|6||Size of the field or the name of the remote command|
|7||Name of the file.|
When the size of the file is given, as in the first three lines of the example output, the file name is also displayed. The file name can be either the name given by the user, as in the /home/amy/tt entry, or a name that BNU assigns internally to data files associated with remote executions, such as D.venus471afd8.

This output tells how many C.* (command) files are waiting for each system. The number in parentheses (2) in the third line of the example indicates that the C.* file has been in the queue for two days.The date and time refer to the current interaction with the system, followed by a report of the status of the interaction.
