Copy this to a text file (strip.awk)

Code:
# strip lines out of file and make new file of lines removed and modified

# set up patterns - any regex will work

BEGIN {
        MY_PAT="835100000000000638"
        NEW_PAT="835100000000000639"
}

# This clause is executed on the opening of each file on the command line
# It first checks to see if this is not the first file and cleans up the
#  previous files and copies the new stripped file to the old file
#  NOTE:  I would prefer if it didn't overwrite the input file...
# It then creates the names and commands it will need later
(FNR == 1) {                    # check if first line of new file
        if ( NR != 1)           # see if this is not first file
        {
                close(FILEOUT)  # if true, then we close previous files
                close(FILELOG)
                system(FILECP)  # do the copy
                system(FILERM)  # remove the work file
        }

        FILEOUT = FILENAME ".strip"     # create striped file name using input file name
        FILELOG = FILENAME ".new"               # create new file

        FILECP = "cp " FILEOUT " " FILENAME     # copy command
        FILERM = "rm " FILEOUT          # remove strip file
}

# This clause executes for every line
# It copies lines from the input file to the appropriate output file
{
        if (  sub(MY_PAT,NEW_PAT) == 0 )      # test for pattern in line
                print > FILEOUT # save to stripped file if pattern not found
        else
                print > FILELOG # save to remove log if pattern match
}

# This clause is executed when the last line of the last file is reached
END {
        system(FILECP)  # clean up last file
        system(FILERM)
}

Then execute:

Code:
awk -f strip.awk <data.file>


It will create a file with .new with the removed lines....

STRIP(1)						       GNU Development Tools							  STRIP(1)

NAME

       strip - Discard symbols from object files.

SYNOPSIS

       strip [-F bfdname |--target=bfdname ]
	     [-I bfdname |--input-target=bfdname ]
	     [-O bfdname |--output-target=bfdname ]
	     [-s|--strip-all] [-S|-g|-d|--strip-debug]
	     [-K symbolname |--keep-symbol=symbolname ]
	     [-N symbolname |--strip-symbol=symbolname ]
	     [-x|--discard-all ] [-X |--discard-locals]
	     [-R sectionname |--remove-section=sectionname ]
	     [-o file ] [-p|--preserve-dates]
	     [-v |--verbose]  [-V|--version] [--help]
	     objfile...

DESCRIPTION

       GNU strip discards all symbols from object files objfile.  The list of object files may include archives.  At least one object file must be
       given.

       strip modifies the files named in its argument, rather than writing modified copies under different names.

OPTIONS

       -F bfdname
       --target=bfdname
	   Treat the original objfile as a file with the object code format bfdname, and rewrite it in the same format.

       --help
	   Show a summary of the options to strip and exit.

       -I bfdname
       --input-target=bfdname
	   Treat the original objfile as a file with the object code format bfdname.

       -O bfdname
       --output-target=bfdname
	   Replace objfile with a file in the output format bfdname.

       -R sectionname
       --remove-section=sectionname
	   Remove any section named sectionname from the output file.  This option may be given more than once.  Note that using this option inap-
	   propriately may make the output file unusable.

       -s
       --strip-all
	   Remove all symbols.

       -g
       -S
       -d
       --strip-debug
	   Remove debugging symbols only.

       --strip-unneeded
	   Remove all symbols that are not needed for relocation processing.

       -K symbolname
       --keep-symbol=symbolname
	   Keep only symbol symbolname from the source file.  This option may be given more than once.

       -N symbolname
       --strip-symbol=symbolname
	   Remove  symbol  symbolname  from the source file. This option may be given more than once, and may be combined with strip options other
	   than -K.

       -o file
	   Put the stripped output in file, rather than replacing the existing file.  When this argument is used, only one objfile argument may be
	   specified.

       -p
       --preserve-dates
	   Preserve the access and modification dates of the file.

       -x
       --discard-all
	   Remove non-global symbols.

       -X
       --discard-locals
	   Remove compiler-generated local symbols.  (These usually start with L or ..)

       -V
       --version
	   Show the version number for strip.

       -v
       --verbose
	   Verbose output: list all object files modified.  In the case of archives, strip -v lists all members of the archive.
