...where SOMETHING is a regexp that will match the line you don't want.

try putting '[0-2][0-9][0-5][0-9] TMU [^W][^X][^:]' (no quotes) as the 'SOMETHING' in the delete function of sed.

This worked in my tests.

Basically you eliminate the four digits followed by the 'TMU' unless it follows that up with 'WX:'

[edit]

Well scratch that, "duh" moment for me, doesn't work if you have more than one entry to search for. It will eventually pull in another '1911 TMP WX:' line as the last line to the previous entry.

Is there nothing in the actual last line (with the 'FWD:' in it) that you can key in on to make that the last line of your sed command?

Otherwise I think but have not tested, that you could pipe the output from what I've done above through 'uniq -d'
