Hi Gurus
I am trying the same type of command through a shell script but it is not working.

$ cat testing.cfg
owner||1
object||1
command_type||1
CREATED_DATE||2
CREATED_BY||2
LAST_UPDATED_DATE||2
LAST_UPDATED_BY||2

$ cat extractedmessage.out
object: RXP_PATIENT
is tag null: Y
command_type: UPDATE
old(2): CREATED_DATE
20-JAN-99
old(3): CREATED_BY
RXP_DM_P001
old(4): LAST_UPDATED_DATE
06-APR-08
old(5): LAST_UPDATED_BY
RXP_DM_P012

p=$\p
cat testing.cfg|while read extractdata
do
whattext=`echo $extractdata|awk -F"||" {'print $1'}`
howmanylines=`echo $extractdata|awk -F"||" {'print $2'}`
echo "sed -n '/${whattext}/,$p' extractedmessage.out|head -${howmanylines}|tail -1"
`sed -n '/${whattext}/,$p' extractedmessage.out|head -${howmanylines}|tail -1` >isitworking.out 2>&1
outputis1=`date`
echo ${outputis1}
done
done

The above script is not working if i put it in a script
cat testing.ksh
p=$\p
cat testing.cfg|while read extractdata
do
whattext=`echo $extractdata|awk -F"||" {'print $1'}`
howmanylines=`echo $extractdata|awk -F"||" {'print $2'}`
echo "sed -n '/${whattext}/,$p' extractedmessage.out|head -${howmanylines}|tail -1"
output1is=`sed -n '/${whattext}/,$p' extractedmessage.out|head -${howmanylines}|tail -1`
echo ${output1is}
done


$ ksh -x testing.ksh
+ p=$p
+ cat testing.cfg
+ read extractdata
+ + echo LAST_UPDATED_DATE||2
+ awk -F|| {print $1}
whattext=LAST_UPDATED_DATE
+ + echo LAST_UPDATED_DATE||2
+ awk -F|| {print $2}
howmanylines=2
+ echo sed -n '/LAST_UPDATED_DATE/,$p' extractedmessage.out|head -2|tail -1
sed -n '/LAST_UPDATED_DATE/,$p' extractedmessage.out|head -2|tail -1
+ + sed -n /${whattext}/,$p extractedmessage.out
+ head -2
+ tail -1
output1is=
+ echo

but if i cut and paste outout of the sed and run it manuall it works fine
$ sed -n '/LAST_UPDATED_DATE/,$p' extractedmessage.out|head -2|tail -1
06-APR-08


Any help will be greatly appreciated.
Thanks in advance

NAME

       largefile - large file status of utilities

DESCRIPTION

       A  large file is a regular file whose size is greater than or equal to 2 Gbyte ( 2**31 bytes). A small file is a regular file whose size is
       less than 2 Gbyte.

   Large file aware utilities
       A utility is called large file aware if it can process large files in the same manner as it does small files. A utility that is large  file
       aware is able to handle large files as input and generate as output large files that are being processed. The exception is where additional
       files  are used as system configuration files or support files that can augment the processing. For example, the file utility supports  the
       -m  option  for	an  alternative "magic" file and the -f option for a support file that can contain a list of file names. It is unspecified
       whether a utility that is large file aware will accept configuration or support files that are large files. If a large file  aware  utility
       does  not accept configuration or support files that are large files, it will cause no data loss or corruption upon encountering such files
       and will return an appropriate error.

       The following /usr/bin utilities are large file aware:

       adb	     awk	   bdiff	 cat	       chgrp
       chmod	     chown	   cksum	 cmp	       compress
       cp	     csh	   csplit	 cut	       dd
       dircmp	     du 	   egrep	 fgrep	       file
       find	     ftp	   getconf	 grep	       gzip
       head	     join	   jsh		 ksh	       ln
       ls	     mdb	   mkdir	 mkfifo        more
       mv	     nawk	   page 	 paste	       pathchck
       pg	     rcp	   remsh	 rksh	       rm
       rmdir	     rsh	   sed		 sh	       sort
       split	     sum	   tail 	 tar	       tee
       test	     touch	   tr		 uncompress    uudecode
       uuencode      wc 	   zcat

       The following /usr/xpg4/bin utilities are large file aware:

       awk	     cp 	   chgrp	 chown	       du
       egrep	     fgrep	   file 	 grep	       ln
       ls	     more	   mv		 rm	       sed
       sh	     sort	   tail 	 tr

       The following /usr/xpg6/bin utilities are large file aware:

       getconf	     ls 	   tr

       The following /usr/sbin utilities are large file aware:

       install	     mkfile	   mknod	 mvdir	       swap

       See the USAGE section of the swap(1M) manual page for limitations of swap on block devices greater than 2 Gbyte on a 32-bit operating  sys-
       tem.

       The following /usr/ucb utilities are large file aware:

       chown	     from	   ln		 ls	       sed
       sum	     touch

       The /usr/bin/cpio and /usr/bin/pax utilities are large file aware, but cannot archive a file whose size exceeds 8 Gbyte - 1 byte.

       The /usr/bin/truss utilities has been modified to read a dump file and display information relevant to large files, such as offsets.

   cachefs file systems
       The following /usr/bin utilities are large file aware for cachefs file systems:

       cachefspack	cachefsstat

       The following /usr/xpg4/bin utility is large file aware for ufs file systems:

	      df

       The following /usr/sbin utilities are large file aware for ufs file systems:

       mkfs	     mount	   ncheck	 newfs	       quot
       quota	     quotacheck    quotaoff	 quotaon       repquota
       tunefs	     ufsdump	   ufsrestore	 umount

   Large file safe utilities
       A  utility  is called large file safe if it causes no data loss or corruption when it encounters a large file. A utility that is large file
       safe is unable to process properly a large file, but returns an appropriate error.

       The following /usr/bin utilities are large file safe:

       audioconvert	audioplay    audiorecord    comm	  diff
       diff3		diffmk	     ed 	    lp		  mail
