Windows batch files to execute this task:

I would like to read a text file in which the variables are in quotes and are on seperate lines.

If the variable is Alphanumeric, then it goes in the Alphanumeric.txt

If the variable contains a Non-Alphanumeric character, then it goes in the Non-Alphanumeric.txt

The list is randon in length.

Thanks in advance for any responses.

What are you trying to achieve, and what have you tried? – user3463 Jun 10 '12 at 3:03

Use the FINDSTR command. It supports grep-like pattern matching.

:: Find all lines matching the pattern
findstr /r ^\"[0-9A-Za-z]\"$ infile.txt > Alphanumeric.txt
:: Find all lines not matching the pattern
findstr /r /v ^\"[0-9A-Za-z]\"$ infile.txt > Non-Alphanumeric.txt
