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.
- Manual
- Jumps directly to the master
source of the online manual.
- <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.
- Source
- Followed by another command,
causes raw source to be generated
for that command. Useful for printing
postscript files without formatting,
with SOURCE PRINT. See examples
.
- 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.
