UUX(1C) UUX(1C) NAME
uux - unix to unix command execution SYNOPSIS
uux [ - ] command-string DESCRIPTION
Uux will gather 0 or more files from various systems, execute a command on a specified system and send standard output to a file on a spec- ified 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 prefixed by system-name!. A null system-name is interpreted as the local system. File names may be one of(1) a full pathname; (2) a pathname preceded by ~xxx; where xxx is a userid on the specified system and is replaced by that user's login directory; (3) anything else is prefixed by the current directory. The `-' option will cause the standard input to the uux command to be the standard input to the command-string. For example, the command uux "!diff usg!/usr/dan/f1 pwba!/a4/dan/f1 > !fi.diff" will get the f1 files from the usg and pwba machines, execute a diff command and put the results in f1.diff in the local directory. Any special shell characters such as <>;| should be quoted either by quoting the entire command-string, or quoting the special characters as individual arguments. FILES

uucp(1) D. A. Nowitz, Uucp implementation description WARNING
An installation may, and for security reasons generally will, limit the list of commands executable on behalf of an incoming request from uux. Typically, a restricted site will permit little other than the receipt of mail via uux. BUGS
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 * will probably not do what you want it to do. The shell tokens << and >> are not implemented. There is no notification of denial of execution on the remote machine. UUX(1C)

uux(1c) uux(1c) Name uux - unix to unix command execution Syntax uux [-] 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 prefixed by system-name!. A null system-name is interpreted as the local system. File names may be one of the following: o A pathname o A pathname preceded by ~xxx, where xxx is a userid on the specified system and is replaced by that user's login directory o 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 execution 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 paren- theses. 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 notifies 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.

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.
