Hi RudiC,

Thanks for the explanation - you made it really simple.

Is it possible to delete the server_n log line which does not contain the log prints ?
in the above example it is server_2 and server_3.

Not sure if this is the most elegant solution:
awk '
/^====/ {PRF = $2 = "0"$2
        {print PRF, $0
' file |
sort -uk1,1 -k3 |
awk '
        {X = $1
         sub ($1 FS, _)
         sub (/^0/, _, $2)
         if (CNT[X] == 2) print L0
         if (CNT[X] >= 2) print
         L0 = $0
========== server_1 ==========
