111111111 is a ssno with 3 records self(amt is 0000001), spouse(amt is 0000002),child (amt is 0000003)
222222222 is a ssno with just 1 record self
333333333 is a ssno with just 1 record self
444444444 is a ssno with just 2 record self(amt is 0000014),spouse(amt is 0000015)

after reading the above file in the WHILE READ LINE DO loop

Basically i am creating 2 more new columns amt_1 and amt_2 in the flat file (sampleout.txt) seperating if any records exists with spouse or child.
for eg: record 21111111110000652 we have 3 records self,spouse & child, i need to create only one record seperating the spouse or child record exists with the amount coulumns seperate spouse amt is 0000002 & child amt is 0000003 like wise the loop should check

Code:
21111111110000652 B86860003OLFXXX000000120081227 0000002 0000003

...etc
Code:

while read line 
do
ssn=`echo $line|cut -c2-10`
ben_type=`echo $line|cut -c28-33`
amount=`echo $line|cut -c34-40`
if [ $rec_cnt -eq 1 ]
then
outline=$line
prior_ssn=$ssn
rec_cnt=2
fi
if [ $ssn -eq $prior_ssn ]
then
if [ $ben_type = "ODL-SP" ]
then
sp_amount=$amount
elif [ $ben_type = "ODL-CH" ]
then
ch_amount=$amount
else
echo 'invalid ben_type'

NAME
truncate - shrink or extend the size of a file to the specified size SYNOPSIS
truncate OPTION... FILE... DESCRIPTION
Shrink or extend the size of each FILE to the specified size A FILE argument that does not exist is created. If a FILE is larger than the specified size, the extra data is lost. If a FILE is shorter, it is extended and the extended part (hole) reads as zero bytes. Mandatory arguments to long options are mandatory for short options too. -c, --no-create do not create any files -o, --io-blocks treat SIZE as number of IO blocks instead of bytes -r, --reference=RFILE base size on RFILE -s, --size=SIZE set or adjust the file size by SIZE bytes --help display this help and exit --version output version information and exit The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (pow- ers of 1000). SIZE may also be prefixed by one of the following modifying characters: '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round down to multiple of, '%' round up to multiple of. AUTHOR
