how to get from each stanza in a file first line (of the stanza)

stanza1_line1
stanza1_line2
stanza1_line3

stanza2_line1
stanza2_line2

stanza3_line1
stanza3_line2



The mached lines should be:

stanza1_line1
stanza2_line1
stanza3_line1

A starting point:
awk '
NF && !nr++
!NF{nr=0}
' /path/to/input > output

Hope This Helps, PH.

thx.

is it also possible to be done with sed?

I am looking for a oneliner to this task. (but of course "awk '^JNF && !nr++^J!NF{nr=0}^J'" is ok!)
