UUCP(1P) POSIX Programmer's Manual UUCP(1P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
uucp — system-to-system copy
uucp [−cCdfjmr] [−n user] source-file... destination-file
The uucp utility shall copy files named by the source-file argument
to the destination-file argument. The files named can be on local or
remote systems.
The uucp utility cannot guarantee support for all character encodings
in all circumstances. For example, transmission data may be
restricted to 7 bits by the underlying network, 8-bit data and
filenames need not be portable to non-internationalized systems, and
so on. Under these circumstances, it is recommended that only
characters defined in the ISO/IEC 646:1991 standard International
Reference Version (equivalent to ASCII) 7-bit range of characters be
used, and that only characters defined in the portable filename
character set be used for naming files. The protocol for transfer of
files is unspecified by POSIX.1‐2008.
Typical implementations of this utility require a communications line
configured to use the Base Definitions volume of POSIX.1‐2008,
Chapter 11, General Terminal Interface, but other communications
means may be used. On systems where there are no available
communications means (either temporarily or permanently), this
utility shall write an error message describing the problem and exit
with a non-zero exit status.
The uucp utility shall conform to the Base Definitions volume of
POSIX.1‐2008, Section 12.2, Utility Syntax Guidelines.
The following options shall be supported:
−c Do not copy local file to the spool directory for transfer
to the remote machine (default).
−C Force the copy of local files to the spool directory for
transfer.
−d Make all necessary directories for the file copy (default).
−f Do not make intermediate directories for the file copy.
−j Write the job identification string to standard output.
This job identification can be used by uustat to obtain the
status or terminate a job.
−m Send mail to the requester when the copy is completed.
−n user Notify user on the remote system that a file was sent.
−r Do not start the file transfer; just queue the job.
The following operands shall be supported:
destination-file, source-file
A pathname of a file to be copied to, or from,
respectively. Either name can be a pathname on the local
machine, or can have the form:
system-name!pathname
where system-name is taken from a list of system names that
uucp knows about. The destination system-name can also be
a list of names such as:
system-name!system-name!...!system-name!pathname
in which case, an attempt is made to send the file via the
specified route to the destination. Care should be taken to
ensure that intermediate nodes in the route are willing to
forward information.
The shell pattern matching notation characters '?', '*',
and "[...]" appearing in pathname shall be expanded on the
appropriate system.
Pathnames can be one of:
1. An absolute pathname.
2. A pathname preceded by ~user where user is a login name
on the specified system and is replaced by that user's
login directory. Note that if an invalid login is
specified, the default is to the public directory
(called PUBDIR; the actual location of PUBDIR is
implementation-defined).
3. A pathname preceded by ~/destination where destination
is appended to PUBDIR.
Note: This destination is treated as a filename
unless more than one file is being
transferred by this request or the
destination is already a directory. To ensure
that it is a directory, follow the
destination with a '/'. For example, ~/dan/
as the destination makes the directory
PUBDIR/dan if it does not exist and puts the
requested files in that directory.
4. Anything else shall be prefixed by the current
directory.
If the result is an erroneous pathname for the remote
system, the copy shall fail. If the destination-file is a
directory, the last part of the source-file name shall be
used.
The read, write, and execute permissions given by uucp are
implementation-defined.
Not used.
The files to be copied are regular files.
The following environment variables shall affect the execution of
uucp:
LANG Provide a default value for the internationalization
variables that are unset or null. (See the Base Definitions
volume of POSIX.1‐2008, Section 8.2, Internationalization
Variables for the precedence of internationalization
variables used to determine the values of locale
categories.)
LC_ALL If set to a non-empty string value, override the values of
all the other internationalization variables.
LC_COLLATE
Determine the locale for the behavior of ranges,
equivalence classes, and multi-character collating elements
within bracketed filename patterns.
LC_CTYPE Determine the locale for the interpretation of sequences of
bytes of text data as characters (for example, single-byte
as opposed to multi-byte characters in arguments and input
files) and the behavior of character classes within
bracketed filename patterns (for example,
"'[[:lower:]]*'").
LC_MESSAGES
Determine the locale that should be used to affect the
format and contents of diagnostic messages written to
standard error, and informative messages written to
standard output.
NLSPATH Determine the location of message catalogs for the
processing of LC_MESSAGES.
Default.
Not used.
The standard error shall be used only for diagnostic messages.
The output files (which may be on other systems) are copies of the
input files.
If −m is used, mail files are modified.
None.
The following exit values shall be returned:
0 Successful completion.
>0 An error occurred.
Default.
The following sections are informative.
This utility is part of the UUCP Utilities option and need not be
supported by all implementations.
The domain of remotely accessible files can (and for obvious security
reasons usually should) be severely restricted.
Note that the '!' character in addresses has to be escaped when
using csh as a command interpreter because of its history
substitution syntax. For ksh and sh the escape is not necessary, but
may be used.
As noted above, shell metacharacters appearing in pathnames are
expanded on the appropriate system. On an internationalized system,
this is done under the control of local settings of LC_COLLATE and
LC_CTYPE. Thus, care should be taken when using bracketed filename
patterns, as collation and typing rules may vary from one system to
another. Also be aware that certain types of expression (that is,
equivalence classes, character classes, and collating symbols) need
not be supported on non-internationalized systems.
None.
None.
None.
