Please assist with awk scirpts:
I need to remove items from a file in a batch:
The file that I will remove from has the following format:
abc00tef:10.81.12.3
abc01tef:10.81.12.3
abc02tef:10.81.12.3

I have a file which is in following format, and will remove line from above file.
the script will look for field before colon(
and will remove entire line.
abc00tef
abc01tef
abc02tef
so from the original file will have:
abc03tef:10.81.12.3
abc04tef:10.81.12.3

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.
