Need to read a dat file sort and store in array

[mantha]

I need to read a file that has no delimeters I am using the cut command to get the data out the problem is how do I read line by line and store the what I am reading in a variable or better yet an array so that I can print and add variables together to get totals.

I would suggest you use an awk program, and imitate the action of 'cut' by using the awk substr() function.

Something like this:

function incr() {
x=`expr $x + 1`
export x
}

function printStuff() {
p=0
      while test $p -lt  $x
      do
           echo "Line segment at $p: ${mystuff[$p]}"
           p=`expr $p + 1`
      done
}
     


declare -a mystuff
x=0
lineno=0

while read line 
do
   echo $line
   mystuff[$x]=`echo $line | cut -c 1-3`
   incr 
   mystuff[$x]=`echo $line | cut -c 8-10`
   incr 
   mystuff[$x]=`echo $line | cut -c 14-16`
   incr 
   lineno=`expr $lineno + 1`
   echo "At line number: $lineno"
done < $1

printStuff

It really performs very badly, BTW.
I would try an awk solution as well.

You could create an array using ksh...

set -A a $(cut -c10-20 file) #----or whatever

echo ${a[0]} #----first element of array "a"

...but awk is more powerful. To get sum total and average is simply...

cut -c10-20 file|awk '{sum+=$1} END {print "Sum=", sum, "Avg=", sum/NR}'
