NAME

uux − unix to unix command execution

SYNOPSIS

uux [ − ] command-string

DESCRIPTION

Uux will gather zero or more files from various systems, execute a command on a specified system and then send standard output to a file on a specified system.  Note that, for security reasons, many installations will limit the list of commands 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.

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 path name;

(2) a path name preceded by ~xxx where xxx is a login name 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 > !f1.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. 

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

uux a!uucp b!/usr/file \(c!/usr/file\)

will send a uucp command to system “a” to get /usr/file from system “b” and send it to system “c”. 

Uux will notify you if the requested command on the remote system was disallowed.  The response comes by remote mail from the remote machine. 

FILES

/usr/lib/uucp/spool spool directory

/usr/lib/uucp/∗ other data and programs

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.
