[SOLVED]need help piping the output from an app... uh, yeah...
Ok, so there is a perl script that runs as a server, on my local host. It tells me which port to use. I want to pipe that output into my browser so I can do the whole thing with a single command. The problem is, I think, that the program doesn't actually exit cause it's running a server, so... so I dunno. Anyway the output looks like this:
Code:
Startup complete. You may now point your browser at this address: http://127.0.0.1:8890

... though obviously the port can be different. so, when I run 'foo.pl|grep http,' I just get the line with address, which is exactly what I want. I've tried a few things to get my browser to open this. So, at first I was trying this:
Code:
link=`foo.pl|grep http` firefox "$link"

This doesn't work. It seems to start the server, but I don't get any output out of, so it's useless unless I check my ports manually. The browser doesn't start either. Then I tried this; cutting out the middle-man, as it were:
Code:
/usr/local/diogenes/perl/diogenes-server.pl|grep http|firefox

This starts the sever and the browser, but it doesn't actually point the browser at the server. not really sure what to try next. edit: bb is on the fritz right now or something. Formatting is really messed up

git-instaweb

GIT-INSTAWEB(1) 						    Git Manual							   GIT-INSTAWEB(1)

NAME

       git-instaweb - Instantly browse your working repository in gitweb

SYNOPSIS

       git instaweb [--local] [--httpd=<httpd>] [--port=<port>]
		      [--browser=<browser>]
       git instaweb [--start] [--stop] [--restart]

DESCRIPTION

       A simple script to set up gitweb and a web server for browsing the local repository.

OPTIONS

       -l, --local
	   Only bind the web server to the local IP (127.0.0.1).

       -d, --httpd
	   The HTTP daemon command-line that will be executed. Command-line options may be specified here, and the configuration file will be
	   added at the end of the command-line. Currently apache2, lighttpd, mongoose, plackup and webrick are supported. (Default: lighttpd)

       -m, --module-path
	   The module path (only needed if httpd is Apache). (Default: /usr/lib/apache2/modules)

       -p, --port
	   The port number to bind the httpd to. (Default: 1234)

       -b, --browser
	   The web browser that should be used to view the gitweb page. This will be passed to the git web--browse helper script along with the
	   URL of the gitweb instance. See git-web--browse(1) for more information about this. If the script fails, the URL will be printed to
	   stdout.

       start, --start
	   Start the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.

       stop, --stop
	   Stop the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance, nor does it close
	   the browser.

       restart, --restart
	   Restart the httpd instance and exit. Regenerate configuration files as necessary for spawning a new instance.

CONFIGURATION

       You may specify configuration in your .git/config

	   [instaweb]
		   local = true
		   httpd = apache2 -f
		   port = 4321
		   browser = konqueror
		   modulepath = /usr/lib/apache2/modules

       If the configuration variable instaweb.browser is not set, web.browser will be used instead if it is defined. See git-web--browse(1) for
       more information about this.
