Syntaxuux [-] command-string
Description
The command gathers 0 or more files from various systems, executes a
command on a specified system, and sends standard output to a file on a
specified system.
The command-string is made up of one or more arguments that look like a
shell command line, except that the command and file names may be pre‐
fixed by system-name!. A null system-name is interpreted as the local
system.
File names may be one of the following:
· A pathname
· A pathname preceded by ~xxx, where xxx is a userid on the speci‐
fied system and is replaced by that user's login directory
· Any other syntax that is prefixed by the current directory.
For example, the following command line gets the f1 files from the usg
and pwba machines, executes a command and puts the results in f1.diff
in the local directory.
uux "!diff usg!/usr/dan/f1 pwba!/a4/dan/f1 > !f1.diff"
When using special shell characters such as <>'!, you should either
quote the entire command-string, or you should quote the special char‐
acters as individual arguments.
The command attempts to get all files to the execution system. If both
the file and command are located on different remote sites, the file is
first brought to the local system and is then transferred to the execu‐
tion system.
If you want to include files as arguments to a command, but you do not
want those files to be processed by enclose the filename in parenthe‐
ses. For example:
uux a!uucp b!/usr/file (c!/usr/file)
The previous example sends a command to system The is transferred from
system to the local system, and then is passed to system When arrives
at system the command executes and sends to system
If the request is not allowed on the remote system, the command noti‐
fies you. This response is sent through remote mail from the remote
machine.
Options-c, -l
Do not copy local file to the spool directory for transfer to the
remote machine. This is the default.
-ggrade
Specifies the grade which is a single letter or number from 0 to 9,
A to Z, or a to z. The highest grade is 0, the lowest grade is z.
The default is A. Lower grades should be specified for high-volume
jobs, such as news.
-n Sends no notification to user.
-p, -
Reads stdin.
-r Queues the job, but does not start the file transfer.
-xdebug
Produces debugging output on stdout. The debug option is a number
between 0 and 9. Higher numbers provide more detailed information.
Debugging is permitted only for those users with read access to
-z Notify the user if the command fails.
Warning
An installation may limit the list of commands executable on behalf of
an incoming request from Typically, a restricted site permits little
other than the receipt of mail through
Restrictions
Only the first command of a shell pipeline may have a system-name!.
All other commands are executed on the system of the first command.
The use of the shell metacharacter asterisk (*) shell metacharacter may
not behave as you expect. The shell tokens (<< >>) are not imple‐
mented.
You are not notified when execution on a remote machine is denied.
Only commands listed in on the remote system are executed at the remote
system.
