MadeInGermany is correct, but you probably want to know why:

If you check the HTML source code you produce you will see that indeed there are three lines as Scott said and suggested. HTML source code, though, is not displayed as it is when you display it using a web browser. The browser interprets it and part of this interpretation is to "interpret away" the line breaks.

MadeInGermany just put the HTML equivalent of line breaks (the "<br />" tags) into the text, which will - when interpreted by a web browser - produce line breaks. Notice, that your text will, when showed in a web browser, look the same if you write:

Code:
Var_name="This is first line.<br />
This is second line.<br />
This is third line."

or

Code:
Var_name="This is first line.<br />This is second line.<br />This is third line."

because the "away-interpretation" of real line breaks works both ways: the browser simply ignores them and it will also ignore their absence.

I hope this helps.

bakunin

/PS: remove the (real) line breaks from your variables content, the browser would ignore them anyway. Their existence is probably the reason why your sed-statement is failing: web browsers ignore line breaks, but sed does not.

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.
