I want to get the line count of a file, excluding the first line. How can I achieve it using sed? File content:

EMP_ID | DEPT_NAME
6965828|Physics One
7510197|Physics One
4789042|Physics One
7991528|Physics One

I tried
#sed -(n-1) '$=' Myfile
the result is 5 however I should be 4.

This is the way you want i guess:
pandeeswaran@ubuntu:~/training$ cat Myfile
EMP_ID | DEPT_NAME
6965828|Physics One
7510197|Physics One
4789042|Physics One
7991528|Physics One
pandeeswaran@ubuntu:~/training$ sed -e '1d' Myfile|sed -n '$='
4
