TRN Command-line Options

Options may generally be unset by typing "+switch".

-a

causes trn to always thread the unread articles on entry to a group. Without this option trn may enter a group in a partially-threaded state and process the unthreaded articles in the background. The down side of this is that the tree display may not be complete when it is first displayed and you may start out at an odd position in the first thread's article tree.

-X {<number>} {<commands>}

If you like using the selector, you'll probably want to use this option to make the selector command (+) the default when a newsgroup is started up with at least number unread articles.

-x {<number>} {<list>}

Enable the extended (threaded) features of trn beyond the rn compatibility mode (this may be the default on your system, use +x if you yearn for the good ol' days).

-e

causes each page within an article to be started at the top of the screen, not just the first page. (It is similar to the -c switch of more(1).)

-m

enables the marking of the last line of the previous page printed, to help the user see where to continue reading.

-S<number>

causes trn to enter subject search mode (^N) automatically whenever an unthreaded newsgroup is started up with <number> unread articles or more.

-F<string>

sets the prefix string for the `F' follow-up command to use in prefixing each line of the quoted article.
