Hi,

Instead of counting the line number which has to be deleted and coming out of the file and then implementing it, you may try an easy way out.
This is an interactive way of deleting a line while reading the file:
1. Enter the file using say vi xx.txt
2. Esc and then press down arrow to reach the line to be deleted
3. Esc click DD (twice)
4. Line is removed

Regards,
Sumedha
