Using awk the output newfile should ONLY delete lines with AT string (4th column) with value greater than 0.10 at (9th column).

Thank you moderator for the kind reply.
awk '$4=="AT" && $9 <= 0.1 && $9 >= 0.0' file
Code above you gave prints line with string AT (4th column) and with value 0.0-0.10 (9th column).
Since one file contains 4000 lines with about 30 different strings at 4th column, it would be better that instead of above task, I would create a code (with help from forum) to just delete rows with AT string and >0.10 value (9th column). This way, rest of the lines with non "AT" string will kept inside the file.

LEARN ABOUT SUNOS
remove
remove(3C) Standard C Library Functions remove(3C)NAME
remove - remove file
SYNOPSIS
#include <stdio.h>
int remove(const char *path);
DESCRIPTION
The remove() function causes the file or empty directory whose name is the string pointed to by path to be no longer accessible by that
name. A subsequent attempt to open that file using that name will fail, unless the file is created anew.
For files, remove() is identical to unlink(). For directories, remove() is identical to rmdir().
See rmdir(2) and unlink(2) for a detailed list of failure conditions.
RETURN VALUES
Upon successful completion, remove() returns 0. Otherwise, it returns -1 and sets errno to indicate an error.
