NAME

       urlview - URL extractor/launcher

SYNOPSIS

       urlview filename [ filename ... ]

DESCRIPTION

       urlview	is a screen oriented program for extracting URLs from text files and displaying a menu from which you may launch a command to view
       a specific item.

CONFIGURATION

       urlview attempts to read ~/.urlview upon startup.  If this file doesn't exist, it will try to read a system wide file in /etc/urlview.conf.
       There are two configuration commands (order does not matter):

       REGEXP regexp
	      urlview  uses a regular expression to extract URLs from the specified text files.  
, 	, 
 and f are all converted to their nor-
	      mal printf(3) meanings.  The default REGEXP is:

       (((https?|ftp|gopher)://|(mailto|file|news):)[^' <>"]+|(www|web|w3).[-a-z0-9.]+)[^' .,;<>":]

       COMMAND command
	      If the specified command contains a %s, it will be subsituted with the URL that was requested, otherwise the URL is appended to  the
	      COMMAND string.  The default COMMAND is:

	      url_handler.sh %s

       Note: You should never put single quotes around the %s.	urlview does this for you, and also makes sure that single quotes eventually show-
       ing up inside the URL are handled properly.  (Note that this shouldn't  happen  with  the  default  regular  expression,  which	explicitly
       excludes single quotes.)

FILES

       /etc/urlview.conf
	      system-wide urlview configuration file

       ~/.urlview
	      urlview configuration file

       printf(3), regcomp(3), regex(7)
