Reverse match in grep
HTML Code:
root@localhost# echo 'server $serviceName -connectorType $connectorType -ipAddress $ipAddress -port $port -domain $domain' | cut -d "-" -f 1
O/P= server $serviceName

when i grep the o/p -v nothing is displayed
now how to output the all data by excluding the O/P (server $serviceName) from the data which i entered in the echo command.

the o/p should look like

HTML Code:
-connectorType $connectorType -ipAddress $ipAddress -port $port -domain $domain

HTML Code:
-connectorType $connectorType -ipAddress $ipAddress -port $port -domain $domain
Or try as
Code:
echo 'server $serviceName -connectorType $connectorType -ipAddress $ipAddress -port $port -domain $domain' | cut -d " " -f3-

Code:
 
^ -- begining of line
 
[^] -- negate the meaning.
 
So [^-] -- except "-" if any thing else comes

An example better expalins:

Code:
 
SCRIPTS>cat input_file
-dsdsd
ds-dsds
avalon:/disk3/upat/SCRIPTS>sed 's/^[^-]*//' input_file
-dsdsd
-dsds
