XTP (1)
file transfer program
SYNOPSIS
xtp
[ -options ... ] <uniform resource locator>
DESCRIPTION
Xtp
is a utility for retrieving, listing, or printing files from a remote
network site, or sending files to a remote network site.
xtp
performs most of the same functions as the ftp(1) program, but does
not require any interactive commands. You simply specify the file transfer
task on the command line and xtp performs the task automatically.
EXAMPLES
To retrieve the file bird.jpg in directory images from host
wizard.dupont.com, use:
xtp ftp://wizard.dupont.com/images/bird.jpg
To retrieve all the files from directory images as user
magick from host wizard.dupont.com, use:
xtp -retrieve ftp://magick@wizard.dupont.com/images
You will be prompted for a password.
To retrieve all the files from directory images as user
magick and password magick from host wizard.dupont.com, use:
xtp -retrieve ftp://magick:magick@wizard.dupont.com/images
OPTIONS
-account \fIpassword\fP
Supply a supplemental password required by a remote system for access
to resources.
-binary
retrieve files as binary. This is the default. Use +binary to
retrieve files as text.
-directory
list the names of files and their attributes that match the filename
component of the uniform resource locator. The filename component is
processed as a regular expression.
-exclude \fIexpression\fP
exclude files that match the regular expression.
This option applies to the -directory, -print, or
-retrieve options.
-file \fIname\fP
store the file with this name.
Refer to the -get and -put option for more details.
-get
get files that match the filename component of the uniform resource locator.
The filename component is expanded by passing it to csh(1).
This option is equivalent to using the ftp get command. However,
if the filename contains globbing characters this option is equivalent
to the ftp mget command. Without globbing characters,
you can store the file locally with a different name by using the
-file option.
-port \fInumber\fP
If no port number is specified, xtp attempts to contact a FTP server
at the default port. Otherwise, the specified port number is used.
-proxy \fIhostname\fP
access the remote host via a proxy ftpd client running on this host.
The default value of this option can be set with the environment variable
xtp_proxy. See ENVIRONMENT for more details. Use +proxy
to prevent proxy connections.
-print
print files that match the filename component of the uniform resource locator.
The filename component is processed as a regular expression.
-prune
process files in the remote directory specified by the directory component
of the uniform resource locator. Do not recursively search for files.
-put
put files that match the filename component of the uniform resource locator.
The filename component is expanded by passing it to csh(1).
This option is equivalent to using the ftp put command. However,
if the filename contains globbing characters this option is equivalent
to the ftp mput command. Without globbing characters,
you can store the file remotely with a different name by using the
-file option.
-retrieve
retrieve files that match the filename component of the uniform resource
locator. The filename component is processed as a regular expression.
Retrieved files are stored on your local host directory as the full
name of the retrieved file. For example, if the retrieved file is
named documents/xtp.man on the remote FTP server, it will appear
in your remote directory as documents/xtp.man.
-timeout \fIseconds\fP
specifies the maximum seconds to complete your remote FTP server request.
If this time expires, the program terminates. The program also terminates if
one tenth of this value is exceeded while logging onto the remote FTP
server.
-type \fIname\fP
identify the remote system type: UNIX, VMS, or other.
The system type is determined automatically, however, you can override
the system type with this option.
-verbose
show all responses from the remote server.
If only the program name is specified on the command line, the program command
syntax and options are listed.
If neither -directory, -print, -put, or -retrieve
are specified on the command line, the file or files specified by the
uniform resource locator is retrieved from the remote network host (as if
-get was specified).
<uniform resource locator> has the format:
protocol://host/[directory/[filename]]
where protocol is ftp and host is [user[:password]]@hostname.
User defaults to anonymous and password defaults to host.domain.
Note that directory/[filename] is interpreted relative to the home
directory for user, thus an absolute pathname must be specified with the
leading /:
ftp://host//tmp/anyfile
As an extension, the filename part of the locator is expanded by the
shell for options -get or -put, otherwise it is processed as a
regular expression. For convenience, the protocol component of the uniform
resource locator (ftp://) may be omitted.
Xtp retrieves files from the remote directory for -get and
puts files in the remote directory for -put. Otherwise, xtp
looks for a file of the form ls-lls-l([Rt])+([Rt])* and assumes it
contains a recursive directory listing. If none is found, xtp
recursively descends the directory hierarchy from the remote directory.
Some remote hosts may have thousands of files causing a significant
delay satisfying your request. This can be wasteful if the files you
are interested in reside in a known directory. You can reduce the
searching required by specifying <remote directory> on the command
line. This limits the filename search to the specified directory and
any of its subdirectories. Alternatively, -prune restricts the
search to the remote directory only.
REGULAR EXPRESSIONS
A regular expression is zero or more branches, separated by
|. It matches anything that matches one of the branches.
A branch is zero or more pieces, concatenated. It matches a match for
the first, followed by a match for the second, etc.
A piece is an atom possibly followed by *, +, or ?.
An atom followed by * matches a sequence of 0 or more matches of
the atom. An atom followed by + matches a sequence of 1 or more
matches of the atom. An atom followed by ? matches a match of
the atom, or the null pattern.
An atom is a regular expression in parentheses (matching a match
for the regular expression), a range (see below), .
(matching any single character), ^ (matching the null pattern at
the beginning of the input pattern), $ (matching the null pattern
at the end of the input pattern), a \' followed by a single
character (matching that character), or a single character with no
other significance (matching that character).
A range is a sequence of characters enclosed in []. It normally
matches any single character from the sequence. If the sequence begins
with ^, it matches any single character not from the rest of the
sequence. If two characters in the sequence are separated by -,
this is shorthand for the full list of ASCII characters between them
(e.g. [0-9] matches any decimal digit). To include a literal
] in the sequence, make it the first character (following a
possible ^). To include a literal -, make it the first or
last character.
ENVIRONMENT
xtp_proxy
Specifies that the remote site should be contacted by proxy. See -proxy.
