UUX(1C)                                                                UUX(1C)


NAME
       uux - unix to unix command execution

SYNOPSIS
       uux  [  -  ]  [ -cClLnprz ] [ -aname ] [ -ggrade ] [ -xdebug ] command-
       string

DESCRIPTION
       Uux will gather zero or more files from various systems, execute a com‐
       mand on a specified system and then 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 path name;

              (2)  a path name preceded by ~user where user is a login name on
              the specified system and is replaced by that user’s login direc‐
              tory;

              (3)  a  path name prefixed by ~; where ~ is expanded to the sys‐
              tem’s public directory (usually /usr/spool/uucppublic);

              (4) a partial pathname, which is prefixed by the current  direc‐
              tory.

       As an example, the command

              uux     "!diff     usg!/usr/dan/file1    pwba!/a4/dan/file2    >
              !~/dan/file.diff"

       will get the file1 and  file2  files  from  the  ‘‘usg’’  and  ‘‘pwba’’
       machines, execute a diff(1) command and put the results in file.diff in
       the local /usr/spool/uucppublic/dan/ 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.

       Uux will attempt to get all files to the execution system.   For  files
       that are output files, the file name must be escaped using parentheses.
       For example, the command

              uux a!wc b!/usr/file1 \(c!/usr/file2 \)

       get /usr/file1 from system ‘‘b’’ and send it to system ‘‘a’’, perform a
       wc command on that file and send the result of the wc command to system
       ‘‘c’’.

       Uux will notify you by mail if the requested command on the remote sys‐
       tem  was  disallowed.   This  notification  can be turned off by the -n
       option.

       The following options are interpreted by uux:

       -    The standard input to uux is made the standard input to  the  com���
            mand-string.

       -aname
            Use  name as the user identification replacing the initiator user-
            id.

       -c   Do not copy local file to the spool directory for transfer to  the
            remote machine (this is the default).

       -C   Force the copy of local files to the spool directory for transfer.

       -ggrade
            Grade is a single letter/number, from 0 to 9, A to Z, or a to z; 0
            is  the  highest, and z is the lowest grade.  The default is A; by
            comparison uucp(1C) defaults to n and  mail  is  usually  sent  at
            grade  C.   Lower grades should be specified for high-volume jobs,
            such as news.

       -l   Try and make a link from the original file to the spool directory.
            If the link cannot be made, copy the file.

       -n   Do not notify the user when the command completes.

       -p   Same as -: The standard input to uux is made the standard input to
            the command-string.

       -r   Do not start the file transfer, just queue the job.

       -xdebug
            Produce debugging output on stdout.  The debug is a number between
            0  and 9; higher numbers give more detailed information. Debugging
            is permitted only for privileged users (specifically,  those  with
            read access to L.sys(5).

       -z   Notify the user only if the command fails.

       -L   Start up uucico with the -L flag. This will force calls to be made
            to local sites only (see uucico(8C)).

FILES
       /usr/spool/uucp       spool directories
       /usr/lib/uucp/∗       UUCP configuration data and daemons

SEE ALSO
       uucp(1C), uucico(8C), uuxqt(8C).

WARNING
       For security reasons, many installations will limit the  list  of  com‐
       mands executable on behalf of an incoming request from uux.  Many sites
       will permit little more than the receipt of mail (see mail(1)) 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.

       When  invoking  uux  from csh(1), the ‘!’ character must be prefixed by
       the ‘\’ escape to inhibit csh’s history mechanism. (Quotes are not suf‐
       ficient.)
