How to tail all lines except first row

For example, I have a file

1
2
3

then I want to output from 2nd row to tail

How can I do it in linux

tail -n+2 my_file

will output all the lines in myfile starting with line 2. (-n2 would show you the last two lines.)

tail has lots more options. Type man tail for complete documentation.

shorter with

$ sed 1d filename

or with awk

$ awk 'NR>1' filename
