UUX(1C)                 GENIX Programmer's Manual                 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 com-
           mand  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 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 direc-
                tory;

                (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.
