NAME

url_handler.pl - Spawn appropriate viewer for a given URL

CONTENTS

SYNOPSIS

url_handler.pl URL

DESCRIPTION

url_handler.pl takes an URL as argument and spawns the first executable viewer found in either $BROWSER_SCHEME or $BROWSER.

ENVIRONMENT

$BROWSER_SCHEME
The user’s preferred utility to browse URLs of type SCHEME. May actually consist of a sequence of colon-separated browser commands to be tried in order until one succeeds. If a command part contains %s, the URL is substituted there, otherwise the browser command is simply called with the URL as its last argument. %% is replaced by a single percent sign (%), and %c is replaced by a colon (:). Examples:
$BROWSER_FTP=‘‘wget:ncftp’’
$BROWSER_GOPHER=‘‘lynx:links’’
$BROWSER_MAILTO=‘‘mutt:pine -url’’
$BROWSER_NEWS=‘‘lynx’’
$BROWSER_NNTP=‘‘lynx’’

$BROWSER
The user’s preferred utility to browse URLs for which there is no special viewer defined via $BROWSER_SCHEME. Again it may actually consist of a sequence of colon-separated browser commands to be tried in order until one succeeds. If a command part contains %s, the URL is substituted there, otherwise the browser command is simply called with the URL as its last argument. %% is replaced by a single percent sign (%), and %c is replaced by a colon (:). Examples:
$BROWSER=‘‘firefox -a firefox -remote openURL\(%s\):opera:konqueror:links2 -g:lynx:w3m’’

SECURITY

url_handler.pl was designed to work together with tin(1) which only issues shell escaped absolute URLs thus url_handler.pl does not try hard to shell escape its input nor does it convert relative URLs into absolute ones! If you use url_handler.pl from other applications be sure to at least shell escaped its input!
