ksh help assigning specific values to variable in script
Hi - Help needed.

I have an input file that looks something like this, but with a lot more entries:
Code:
A
Customer1
B
4500
C
8000
A
Customer2
B
6422
C
8922

I need to be able to print details for each customer on one line per customer.
ie. if I could print these to a file and then cat the file I would expect something like the below
Code:
a=Customer1,b=4500,c=8000
a=Customer2,b=6422,c=8922

and so on...

I want to be able to do this in a ksh script - any ideas ? SmilieSmilieSmilie

If you want to avoid the penalty of calling an external utility such as sed, you can do what you want to do entirely within your shell.
Code:
#!/bin/ksh93

n=0
output=""

while read line
do
   output="$output$line"
   if (( n%2 == 0 )); then
      output="$output="
   else
      output="$output "
   fi
   (( n++ ))
   if (( n == 6 )); then
     echo "$output"
     output=""
     n=0
   fi
done < file

Try paste...
Code:
$ cat file1
A
Customer1
B
4500
C
8000
A
Customer2
B
6422
C
8922
$ paste -s -d '=,=,=\n' file1 > file2
$ cat file2
A=Customer1,B=4500,C=8000
A=Customer2,B=6422,C=8922
