Command Line Syntax
The generic syntax is:
webbot [ options ] [ docaddress [ keywords ]]
The order of the options is not important and options can in fact be specified on either side of any
docaddress. Currently available options are:-
Getting Help
- -help or -?
- Load this file from directly into the browser
- -v [ a | b | c | g | p | s | t | u ]
- Verbose mode: Gives a running commentary on the program's attempts to read data in various
ways. As the amount of verbose output is substantial, the
-v
option can now be followed
by zero, one or more of the following flags (without space) in order to differentiate the verbose
output generated:
- a: Anchor relevant information
- b: Bindings to local file system
- c: Cache trace
- g: SGML trace
- p: Protocol module information
- s: SGML/HTML relevant information
- t: Thread trace
- u: URI relevant information
The -v
option without any appended options shows all
trace messages. An example is
-vpt
showing thread and protocol trace messages
- -version
- Prints out the version number of the software, and the version
number of the WWW library, and exits.
Configuration Options
- -img
- Test include inlined images
- -l [ file ]
- Specifies a log file with a list of visited documents. The default
value is "www-log"
- -link
- Fetch all links from this document
- -n
- Non-interactive mode. Outputs the formatted document to the
standard output, then exits. Pages are delimited with form feed (FF)
characters.
- -o [ file ]
- Redirects output to specified file. The default value is
"www-out". This mode forced non-interactive mode
- -r <file>
- Rule file, a.k.a. configuration file. If this is specified, a rule file may be used to map URLs,
and to set up other aspects of the behavior of the browser. Many rule files may be given with
successive -r options, and a default rule file name may be given using the WWW_CONFIG
environment variable.
- -single
- Singlethreaded mode. If this flag is set then the browser uses
blocking, non interruptible I/O in interactive mode. Non-interactive
mode always uses blocking I/O.
- -timeout <n>
- Timeout in seconds on sockets
If present, the next argument (docaddress) is the
hypertext address , of the document at which you want to start browsing. You may want to define
an alias for www followed by name of your favorite index. Any
further command line arguments are taken as keywords. The first argument must refer to an index in
this case. The index is searched for entries matching the keywords, and a list of matching entries
is displayed.
