Hi all,

Simple problem I am not getting. Please apply cluebat.

I have an accumulator variable inside a while loop.  I want access to
the contents after the while loop completes but am getting a null value.

Thanks,

#!/bin/bash
#
# to test make file foo with single line in same directory as test
# script

cat foo | while read line ; do
  let error_code=$error_code+1
  echo "error_code inside while loop $error_code"
done

echo "error_code outside while loop $error_code"
# end test script
