I need to pass variable to this command, somehow it doesn't work.

Code:
awk -F"=" '!/ABCD/ {print $0}; /ABCD/ {print $1"=NEW_VALUE"}'  file > new_file

I use below command, it throw out error.
Code:
awk -F"=" -v var="$new_value" '!/ABCD/ {print $0}; /ABCD/ {print $1"=${var}"}'  file > new_file

simplified and fixed:
Code:
awk -F= -v var="$new_value" '/ABCD/ {$1= "=" var} 1' file > new_file
