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
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
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
/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.
