Bash - sed - Remove first word from line which can begin eventually with blank
hello.
How to remove first word from line. The line may or may not start with blank.

Code:
NEW_PARAM1=$(magic-command "    -t --protocol=TCP  -P 12345-u root -h localhost ")
NEW_PARAM2=$(magic-command "-t --protocol=TCP  -P 12345 -u root -h localhost ")

I want NEW_PARAM1 equal to NEW_PARAM2 equal to "--protocol=TCP........"

I don't care the number of blank following the first word.
Code:
"-t --protocol=TCP" or "-t         --protocol=TCP"  or "   -t         --protocol=TCP"

is the same for me.
What is important is to remove the first word and keep the rest as is.

Any help is welcome

protocols

protocols(4)						     Kernel Interfaces Manual						      protocols(4)

NAME

       protocols - Defines the Internet protocols used on the local host

SYNOPSIS

       /etc/protocols

DESCRIPTION

       The /etc/protocols file contains information about the known protocols used in the DARPA (Defense Advanced Research Projects Agency) Inter-
       net.  Each protocol is represented by a single line in the protocols file.  Each entry is of the form: Name Number Aliases

       The fields contain the following information: Official Internet protocol name.  Protocol number.  Unofficial names used for the protocol.

       Items on a line are separated by one or more spaces or tab characters.  Comments begin with the # (number sign), and routines  that  search
       the  protocols  file  do  not interpret characters from the beginning of a comment to the end of the line.  A protocol name can contain any
       printable character except a field delimiter, newline character, or comment character.

       The lines in the file appear as follows: # # Internet (IP) protocols # ip      0    IP	      # internet protocol, pseudo protocol  number
       icmp	1     ICMP	 # internet control message protocol igmp    2	  IGMP	     # internet group management protocol ggp	  3    GGP
       # gateway-gateway protocol tcp	  6    TCP	  # transmission control protocol egp	  8    EGP	  # exterior gateway protocol  pup
       12   PUP        # PARC universal packet protocol udp	17   UDP	# user datagram protocol hmp	 20   HMP	 # host monitoring
       protocol rdp	27   RDP	# "reliable datagram" protocol
