Reason: Code tags not icode tags
@Spacebar
Not working still. Thanks for you input.
Taking this data
stored in
"$temporary_file"
then

The next problem is this data set (members 5-6) may or may not appear.
So algorithmically speaking and where I am getting stuck...
Next step:
1. search array for email address (using the @ symbol here to keep things simple)
Then I am going to use conditional / control flow statements using the position of the email address to further parse the data.
Not sure if this helps, but wanted to add some context.
Thanks in advance, for any help.

If what you want to do is print lines in the file named by $temporary_file that contain an @, that would much more simply be done by:
If you want a way to determine if the expansion of a shell variable ($x in this example) contains an @ using only features that are available in all standards conforming shells, you could try something like:
