UUX(1C)             UNIX Programmer's Manual              UUX(1C)

NAME
     uux - unix to unix command execution

SYNOPSIS
     uux [ - ] command-string

DESCRIPTION
     _U_u_x will gather 0 or more files from various systems, exe-
     cute a command on a specified system and send standard out-
     put to a file on a specified system.

     The _c_o_m_m_a_n_d-_s_t_r_i_n_g 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 ~_x_x_x; where _x_x_x 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 _u_u_x com-
     mand to be the standard input to the _c_o_m_m_a_n_d-_s_t_r_i_n_g.

     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, exe-
     cute a _d_i_f_f 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 _c_o_m_m_a_n_d-_s_t_r_i_n_g, or quoting the
     special characters as individual arguments.

     incoming request from _u_u_x. Typically, a restricted site will
     permit little other than the receipt of mail via _u_u_x.

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.
