Couple of comments:

1. Output to file2.dat and file3.dat should be appended (use redirection symbol >>).

2. File being pasted if condition is true is missing the .dat file extension.

3. Variable avg in awk statement is not available from outside in IF condition. You can do something like this:
Code:
var_avg=$(awk ........)

4. If you want to compare percentage .28 then you should divide by 100 in awk.
