Tools Record count problem using sed command
Hi,

I have a script which removes 2 header records and 1 trailer record in a list of files. The commands doing the actions are
sed '1,2d' $file > tempfile1.dat
sed '$d' < tempfile1.dat > $output.txt
Its working fine for all records except a file having size=1445509814 and number of records=13152342. The output has only 5297671 records instead of being just 3 less than the original count.
Is there any limitation on the number of records that the sed command can process?
Some details-
>uname -a
SunOS xx 5.10 SunOS_Development sun4u sparc SUNW,Sun-Fire

>df -k .
Filesystem kbytes used avail capacity Mounted on
xx 67091946 64377506 2043521 97% xx

>df -k /tmp

swap 17337536 1504840 15832696 9% xx

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
