you can use
Code:
# tail +2 file.dat > newfile

or
Code:
# more +2 file.dat > newfile

to get 2nd line of file onwards. I leave it to you to do the rest. Try.

rmdel(1)						      General Commands Manual							  rmdel(1)

Name
       rmdel - remove a delta from an SCCS file

Syntax
       rmdel -r files

Description
       The command removes the delta specified by the SID from each named SCCS file.  The delta to be removed must be the most recent delta in its
       branch in the delta chain of each named SCCS file.  In addition, the  specified delta must not be that of a version being  edited  for  the
       purpose	of  making  a delta, for example, if a p-file exists for the named SCCS file, the  specified delta must not appear in any entry of
       the p-file).  For further information, see

       If a directory is named, behaves as though each file in the directory were specified as a named file, except that non-SCCS files (last com-
       ponent  of the path name does not begin with s.)  and unreadable files are silently ignored.  If - is given as the name, the standard input
       is read and each line of the standard input is taken to be the name of an SCCS file to be processed.  Non-SCCS files and  unreadable  files
       are silently ignored.

       Certain permissions are necessary to remove a delta.  If you make a delta or own the file and directory, you can remove it.

Options
       -rSID   Specifies the delta version number.

Diagnostics
       Use for explanations.

Files
       x-file  For further information, see
       z-file  For further information see
