To print a specific line from a file

tail -n +<N> <file> | head -n 1
Tail is much faster than sed, awk because it doesn't check for regular expressions.
Sample Output
$ tail -n +5 /var/log/dmesg | head -n 1

What does "much faster mean"? I made a test with 100000 lines file - difference is ~1ms

The file i tested the posted command with is 21GB. 100k lines is a small file. It is about maybe 10MB in which case the difference is hard to see.
