Awk第3列（如果第二行与一个变量匹配）

Question

I am new to Awk and linux. I want to print 3rd column if 2nd column matches with a variable.

file.txt
1;XYZ;123
2;ABC;987
3;ZZZ;999

So I want to print 987, After checking if 2nd column is ABC

name="ABC"
awk -F';' '$2==$name { print $3 }' file.txt

But this is not working. Please help. Please note, I want to use AWK only, to understand how this can be achieved using awk.

Answer 1

Do following and it should fly then. In awk variables don't work like shell you have to explicitly mention them by using -v var_name in awk code.

name="ABC"
awk -F';' -v name="$name" '$2==name{ print $3 }' file.txt
