- xtp [ -options ... ] <uniform resource locator>
Back to Contents
- 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.

- To retrieve the file bird.jpg in directory images from host
wizard.mystic.es.dupont.com, use:
- xtp ftp://wizard.mystic.es.dupont.com/images/bird.jpg
- To retrieve all the files from directory images
from host wizard.mystic.es.dupont.com, use:
- xtp -retrieve ftp://wizard.mystic.es.dupont.com/images/
You will be prompted for a password.
- To retrieve all the files from directory images
as user cristy and password magick from host
wizard.mystic.es.dupont.com, use:
- xtp -retrieve ftp://cristy:magick@wizard.mystic.es.dupont.com/images/

- -account password
- 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 expression
- exclude files that match the regular expression.
- This option applies to the -directory, -print, or
-retrieve options.
- -file name
- 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.
- -ident password
- Supply a password required by a remote system. This
defaults to your username and hostname.
- -port number
- 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 hostname
- 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 seconds
- 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 name
- 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).
- 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.

- 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.
