uux - unix to unix command execution
uux [ - ] command-string
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 prefixed by system-name!. A null sys-
tem-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.
/usr/uucp/spool - spool directory
/usr/uucp/* - other data and programs
D. A. Nowitz, Uucp implementation description
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.
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.
