Unable to restart varnish using "service varnish restart"

Question

I made changes in "/etc/default/varnish" as well as the vcl file "/etc/varnish/default.vcl" and therefore want to restart varnish.

But I'm unable to figure out what's wrong. Already spent more than an hour lookijng into it but no luck. Following are the details:

nish@styx:~$ sudo service varnish restart
[sudo] password for nish: 
 * Stopping HTTP accelerator varnishd                                    [fail] 
 * Starting HTTP accelerator varnishd                                    [fail]

Fixed the problem by removing line breaks from the "/etc/default/varnish" file.

DAEMON_OPTS="-a :80 \
             -T localhost:1234 \
             -f /etc/varnish/default.vcl \ 
             -s malloc,256m"

to

DAEMON_OPTS="-a :80 -T localhost:1234 -f /etc/varnish/default.vcl -s malloc,256m"
