"cut" problem with leading spaces
I'm trying to use the cut command on the following output to remove the first 2 columns (this is output of "find -ls", if anyone wondering, which for some bizarre reason inserts leading spaces on AIX):

file.txt:

Code:
   16    4 -rw-r--r--  1 root      tech          3186 Apr 15 04:00 ./file1
 2140    0 -rw-r--r--  1 root      security         0 Apr 15 06:30 ./file2
 2141   18 -rw-r--r--  1 root      security     18126 Apr 15 09:00 ./file3
 1072    1 -rw-r--r--  1 root      tech           112 Apr 15 09:00 ./file4
  637   15 -rwxr-----  1 root      system       14515 Apr 15 12:08 ./file5
   18    2 -rwxr-x---  1 root      tech          1977 Apr 15 12:16 ./file6
 1140    1 -rw-r--r--  1 root      tech           128 Apr 15 09:00 ./file7
 1320    1 -rw-r--r--  1 root      tech            37 Apr 14 14:54 ./file8

output of "cat test.txt | cut -d ' ' -f 3-"

Code:
 16    4 -rw-r--r--  1 root      tech          3186 Apr 15 04:00 ./file1
   0 -rw-r--r--  1 root      security         0 Apr 15 06:30 ./file2
  18 -rw-r--r--  1 root      security     18126 Apr 15 09:00 ./file3
   1 -rw-r--r--  1 root      tech           112 Apr 15 09:00 ./file4
637   15 -rwxr-----  1 root      system       14515 Apr 15 12:08 ./file5
 18    2 -rwxr-x---  1 root      tech          1977 Apr 15 12:16 ./file6
   1 -rw-r--r--  1 root      tech           128 Apr 15 09:00 ./file7
   1 -rw-r--r--  1 root      tech            37 Apr 14 14:54 ./file8

Seems like the leading spaces are causing this problem. Is there a workaround to this as far as cut is concerned? Perhaps it's easier to just remove the leading spaces (not sure how to do it), any help will be appreciated.

nbdst

NBDST(8)						    BSD System Manager's Manual 						  NBDST(8)

NAME

     nbdst -- NetBoot deferred shadow tool

SYNOPSIS

     nbdst [-recycle | -preallocate size] devnode shadowfile

DESCRIPTION

     nbdst is used during NetBoot to associate a shadow file with the disk image being used as the root device. After the shadow file is attached,
     subsequent writes to the root device will be redirected to the shadow file, which normally resides on local storage.  nbdst is invoked by
     /etc/rc.netboot

ARGUMENTS

     The following arguments must be specified:
     devnode	    The device node of the root device, in the form "disk0"
     shadowfile     Path to a shadow file which will be created and associated with the NetBoot root device

OPTIONS

     -recycle  If a shadow file already exists, reset it and use it again.  Otherwise, information written to an existing shadow file will reap-
	       pear.  Reusing a previous shadow file without resetting it requires that the shadow file be created with the same base image.

     -preallocate size
	       Set the shadow file to the given size up front.	This forces a reset of the shadow file (like -recycle).

NOTE

     nbdst can only be run as root.
