Using sed, how do I return the last occurance of a match until the End Of File?
(FYI this has been simplified)

So far I’ve tried:

sed -n '/ Statistics |/,$p' logfile.log

Which returns all lines from the first match onwards (almost the entire file)

I’ve also tried:

$linenum=`tail -400 logfile.log | grep -n " Statistics |" | tail -1 | cut -d: -f1`
sed "$linenum,\$!d" logfile.log

This works but won’t work over an ssh connection in one command, really need it all to be in one pipeline.

Format of the log file is as follows:

(There are statistics headers with sub data written to the log file every minute, the purpose of this command is to return the most recent Statistics header together with any associated errors that occur after the header)

Statistics |
   Stuff
   More Stuff
   Even more Stuff
Statistics |
   Stuff
   More Stuff
Error: incorrect value
Statistics |
   Stuff
   More Stuff
   Even more Stuff
Statistics |
   Stuff
Error: error type one
Error: error type two

EOF

Return needs to be:

Statistics |
   Stuff
Error: error type one
Error: error type two
