shell command using sed editor
echo http://www.domain.com/?params | sed -e 's;https\?://;;' | sed -e 's;/.*$;;'
output www.domain.com
How can i use the unix awk editor to output this string?
awk {print} ?

Do you REALLY need awk, as opposed to cut or some other tool? If you post a FEW lines of representative input, including any you think will be hard to parse, and expected output you might get a better answer than if you don't.Ed Morton– Ed Morton2014-09-03 15:58:56 +00:00Commented Sep 3, 2014 at 15:58

You could try this,
$ echo http://www.domain.com/?params | awk -F/ '{print $3}'
www.domain.com
Through grep,
$ echo http://www.domain.com/?params | grep -oP '(?<=/)[^/]+(?=/)'
www.domain.com
Through sed,
$ echo http://www.domain.com/?params | sed 's/.*\/\([^\/]\+\)\/.*/\1/'
www.domain.com

In addition to all the perl/sed/awk/grep, this is actually pretty well-suited for cut:
$ echo http://www.domain.com/?params | cut -d/ -f3
www.domain.com

With awk and gsub:
$ echo http://www.domain.com/?params | awk '{gsub("\\/\\?params$", ""); print}'
http://www.domain.com
$ echo http://www.domain.com/?params | awk '{gsub("\\/\\?params$",""); gsub("^http://",""); print}'
www.domain.com
Or, (thanks Avinash Raj):
$ echo http://www.domain.com/?params | awk '{gsub(/\/\?params$|^http:\/\//,""); print }'
www.domain.com
Perl:
$ echo http://www.domain.com/?params | perl -pe 's/^http:\/\/([^\/]+).*/\1/'
www.domain.com
Or:
$ echo http://www.domain.com/?params | perl -ne 'print "$1\n" if /^http:\/\/([^\/]+)/; '
www.domain.com

single gsub will do this job
$ echo http://www.domain.com/?params | awk '{gsub(/\/\?params|http:\/\//,"")}1'Mix it up a bit
expr match http://www.domain.com/?params '.*/\(.*\)/'
or
expr http://www.domain.com/?params : '.*/\(.*\)/'
Incase there are more slashes later on
expr http://www.domain.com/?params/ : '.*//\([^/]*\)/'
Incase something really wierd is going on with the slashes
expr http://www.domain.com/?params/ : '[^/]*//\([^/]*\)/'
