UU CP Implementation Description
UUX - UNIX to UNIX Execution
the execution machine for execution.
The execute file contains a script that is processed by the uuzqt program. It is made up of
several lines, each of which contains an identification character and one or more arguments.
The lines are described in the subsections below. Here is a summary of the types of lines that
appear in the file. They are described in detail in the sections following.
U~er
Line Identifies the requestor's login name and system.
File Line
Identifies a filename for transmission.
Standard Input Line
Specifies a standard input file.
Standard Output Line
Specifies a standard output file.
Command Line
Identifies a UNIX system command for uuzqt to execute.
3.1. User Line
U user system
w
here the
u,er
and
'lIlfem
are the requester's login name and system.
3.2. Required File Line
F file- name real-name
where file-name is a unique name used for file transmission and real-name is the last part of the
actual file name (contains no path information).
Zero or more of these lines may be present. The uuzqt program checks for the existence of all
these files before the command is executed.
3.3. Standard Input Line
I file-name
The standard input is either specified
by
a
<
in the command-string or inherited from the stan-
dard input of the uux command if the "-" option is used. If a standard input is not specified,
/ dev/ null
is used. Note that if there is a standard input specified, it will also appear in an "F"
line.
3.4. Standard Output Line
o
file-name system-name
The standard output is specified by a > within the command-string. If a standard output is
not specified, /
dev/ null
is used. Note that the appending to a file by using> > is not imple-
mented.
