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 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

              (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
       /usr/uucp/spool - spool directory
       /usr/uucp/* - other data and programs

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.
