Commands
The following commands are available at the prompt within
www. Some are disabled when not applicable.
All commands may be abbreviated. Case is not significant.
- Help
- Gives a list of available commands depending on the context, the version
number of the www program, and the
hypertext address,
(or UDI) of the document you are reading.
- <.Return>.
- Just hitting Return displays the next page of the current document.
- <.number>.
- Typing a number by itself follows the corresponding reference
from the currently displayed document.
- Find keywords
- Queries the current index with the supplied keywords (separated by blanks).
The interpretation of the keywords depends on the particular information server
you're looking at. In most cases, it will search a database for entries matching
the keywords, and will display the results with possibly links to further details.
For more complex queries, instructions should be present in the cover page.
The "Find" command can be omitted if the first keyword does not conflict with
another www command.
- Back
- Goes back to the document you were reading before.
- Home
- Goes back to the first document you were reading.
- Recall
- Without a parameter, gives a numbered list of the documents
you have visited. To select one, type "Recall" followed by the number.
- List
- Gives a numbered list of the links from the current document, giving the
title of the target documents (or addresses if no title). To follow a link,
type the number by itself as above.
- Next, Previous
- Goes to the next or previous document in the list of pointers from the
document that led to the current one. This is better explained with an example:
suppose you are reading a document which looks like a menu, and you want to read
all entries in turn. You first type "1" to read the first referred document (by
following the first link), and then you type "next" or just "n" to read the next
one from the menu, without actually coming back to the menu and typing "2", etc.
- Go <.address>.
- Goes to the document represented by the given
hypertext address,
which is interpreted relatively to the current document.
- Up, Down
- Scrolls up or down one page in the current document.
- Top, Bottom
- Goes to the top or the bottom of the current document.
- Verbose
- Toggles verbose mode (for maintenance purposes).
- Quit
- Leaves the application.
On Unix versions, the following extra commands are available:
- Print
- Prints the current document, without the numbered document references.
A background www is launched to do that, and its output is piped to the
command defined by the environment variable WWW_PRINT_COMMAND ("lpr" by default).
- >. file, >.>. file
- Saves or appends the current document to the given file, without the
numbered document references. A background www is launched to do that.
- | command
- Pipes the current document to the given command, without the
numbered document references. A background www is launched to do that.
- ! command
- Executes the given shell command without leaving www.
- CD (or LCD) directory
- Changes the local working directory. "! cd directory" won't do this
because it applies to a subshell.
