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.dupont.com, use:
xtp ftp://wizard.dupont.com/images/bird.jpg
To retrieve all the files from directory images as user cristy from host wizard.dupont.com, use:
xtp -retrieve ftp://cristy@wizard.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.dupont.com, use:
xtp -retrieve ftp://cristy:magick@wizard.dupont.com/images
This option applies to the -directory, -print, or -retrieve options.
Refer to the -get and -put option for more details.
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.
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.
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.
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.
The system type is determined automatically, however, you can override the system type with this option.
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 /:
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 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.
