I am having a string like this: 

$abc= ' NAME=ABCDEF 128 @#
CLASS= @# EIGHT 8.58
SCHOOL=GRAMMAR HIGH L-1 '

[download]

I am accepting a variable ($input_var) from the user. Based on the variable the user provides I want to delete that line.

Ex: If the input variable provided is NAME, I want to delete: NAME=ABCDEF 128 @#

Ex: If the input variable provided is CLASS, I want to delete: CLASS= @# EIGHT 8.58

I want to write some thing like
$abc =~ s/$input_var(Has to fill some thing here)//;

Early help is highly appreciable.
Thanks in Advance.
