Hello,
I am trying to remove everything coming after empty line under ubuntu14.04.
How may I do it?

file:

aaa
020390
bb00id3
c03wisi

209dl
x092sia
0290s

I expect:

aaa
020390
bb00id3
c03wisi

Thank you
Boris

sed '/^$/q'   filename

Meaning: search for a line containing only begin (^) and end of line ($). Then quit (q).

To not print the empty line:

sed -n '/^$/q;p' file

sed '/^$/,$d' file

awk NR==1 RS= file
