Shell script to remove some content in a file

How can I remove all data that contain domain e.g zzgh@something.com, sdd@something.com.my and gg@something.my in one file? so that i only have data without the domain in the file.

Here is the file structure "test.out"

more test.out
   1 zzztop@b.com
   1 zzzulll
   1 zzzullll@s.com.my
   1 zzzuri@b.com
   1 zzzurita@b.my
   1 zzzx
   1 zzzxxx92
   1 zzzxxx@b.com
   1 zzzxy85@s.com
   1 zzzz
   1 zzzz1861@b.com
   1 zzzz23@b.com.my
   1 zzzz5879
   1 zzzz888
   1 zzzz@s.my
   1 zzzzdaud
   1 zzzzin
   1 zzzzz
   1 zzzzz@b.com
   1 zzzzz@s.com
   1 zzzzznndr@b.com
   1 zzzzzz@b.com

output should be like this,

zzzulll
zzzx
zzzxxx92
zzzz
zzzz5879
zzzz888
zzzzdaud
zzzzin
zzzzz

One way would be..

awk '!/@/ {print $2}' inputfile > outfile

One way you can start is learning regular expressions.

Here is another way of solving your problem using 'sed':

sed '/@/d' Input_File
