NEWS(1) USER COMMANDS NEWS(1)
NAME
news - display system news
SYNOPSIS
news [-adDeflnpvxs] [[article1] [article2] ..]
DESCRIPTION
The news command keeps you informed of news concerning the system. Each news item is contained in a separate file in the /var/lib/sysnews
directory. Anyone having write permission to this directory can create a news file.
If you run the news command without any flags, it displays every unread file in the /var/lib/sysnews directory.
Each file is preceded by an appropriate header. To avoid reporting old news, the news command stores a currency time. The news command con-
siders your currency time to be the date the $HOME/.news_time file was last modified. Each time you read the news, the modification time of
this file changes to that of the reading. Only news item files posted after this time are considered unread.
OPTIONS
-a, --all
Display all news, also the already read news.
-d, --datestamp
Add a date stamp to each article name printed. this can only be used with the -nl flags.
-D, --datefmt <fmt>
Specify a date format, see the strftime(3) man page for more details. the default format is (%b %d %Y)
-f, --newsdir <dir>
Read news from an alternate newsdir.
-l, --oneperline
One article name per line.
-n, --names
Only show the names of news articles.
-p, --page
Pipe articles through $PAGER or more(1) if the $PAGER environment variable is not set.
-s, --articles
Reports the number of news articles.
MAINTAINER OPTIONS
-e, --expire #
Expire news older than # days.
-x, --exclude a,b,c
A comma separated list of articles which may not be expired. if a file named .noexpire exists in the /var/lib/sysnews direcory,
