Problem in getting data from a loop using grep and cut

The script is following :

for each_rec in <file_name>
do
  count=`cut -c -2 ${each_rec} | grep "45"`
  echo ${count}
  if [[ ${count} -eq 45 ]] then
    amount=`cut -c 24-35 ${each_rec}`
    echo ${amount}
  else
    echo "failed"
  fi
done

And the file looks like below :

01000007683+0000013071+001449750.71+001596774.86 2010-09-27201009

I am trying to fetch the corresponding column, where the first two field matches with 45. But, every time the cut is fetching the whole column.
Please help me on this .

$ ruby -F'\+' -ane 'puts $F[2] if $F[0][0,2]=="45"' file
000011481.00

#!/bin/ksh
for each_rec in `cat <filename>`
do
count=`echo ${each_rec}|cut -c -2 | grep "45"`
echo ${count}
if [[ "${count}" = "45" ]]; then
amount=`echo ${each_rec}|cut -c 24-35`
echo ${amount}
else
echo "failed"
fi
done

The quick way:

grep \^"45" filename | cut -f3 -d+
000011481.00

Alternatively modifying your script to use a "while" not a "for" loop. There is never a reason to use a "for" loop with an open-ended list.
Also corrected various syntax anomalies. Note that "cut" either takes input from a pipeline or a file (in this case we need to use "echo" to get the record onto a pipeline).

cat filename | while read each_rec
do
  count=`echo "${each_rec}" | cut -c1-2`
  if [ ${count} -eq 45 ]
  then
       amount=`echo "${each_rec}" | cut -c24-35`
       echo "${amount}"
  fi
done
000011481.00

awk -F + '/^45/ {print $3}' infile

000011481.00
