xscreensaver-text

xscreensaver-text(1)                                            XScreenSaver manual                                           xscreensaver-text(1)

NAME

       xscreensaver-text - prints some text to stdout, for use by screen savers.

SYNOPSIS

       xscreensaver-text [--verbose] [--columns N] [--text STRING] [--file PATH] [--program CMD] [--url URL]

DESCRIPTION

       The  xscreensaver-text  script  prints  out  some text for use by various screensavers, according to the options set in the ~/.xscreensaver
       file.  This may dump the contents of a file, run a program, or load a URL.

OPTIONS

       xscreensaver-text accepts the following options:

       --columns N or --cols N
               Where to wrap lines; default 72 columns.

       --verbose or -v
               Print diagnostics to stderr.  Multiple -v switches increase the amount of output.

       Command line options may be used to override the settings in the ~/.xscreensaver file:

       --string STRING
               Print the given string.  It may contain % escape sequences as per strftime(2).

       --file PATH
               Print the contents of the given file.  If --cols is specified, re-wrap the lines; otherwise, print them as-is.

       --program CMD
               Run the given program and print its output.  If --cols is specified, re-wrap the output.

       --url HTTP-URL
               Download and print the contents of the HTTP document.  If it contains HTML, RSS, or Atom, it will be converted to plain-text.

               Note: this re-downloads the document every time it is run!  It might be considered abusive for you to point this at  a  web  server
               that you do not control!

ENVIRONMENT

       HTTP_PROXY or http_proxy
           to get the default HTTP proxy host and port.

BUGS

       The RSS and Atom output is always ISO-8859-1, regardless of locale.

       URLs should be cached, use "If-Modified-Since", and obey "Expires".
