Separate special character fields
Hi,

I have a file with User ID and User Name. Sometimes the file has speical characters in the USer ID and it creates problems.

I want to allow all those fields to be processed which have only numbers and characters.

I do NOT want to process those fields with Speical Characters.


How to search and filter?

Appreciate your help.

Regards

Pseudo-code:
Code:
for field in (all fields)
do
  if echo $field | grep[list of ok characters]
  then
    process_the_field
  fi
done
