Darrel, Are you trying to get the following to work? WMO<tab>^(TI[GC]...) (KNES) ([0-3][0-9])([0-2][0-9])([0-5][0-9]) <tab>FILE<tab>-close /realtime4/sat/satraw/(\3:yyyy)(\3:mm)(\3:dd)\2\4\5.\1 <tab>EXEC<tab>/home/ldm/etc/sat-none.sh (\3:yyyy)(\3:mm)(\3:dd)\2\4\5.\1 If so, then it should be rewritten as two separate entries: WMO<tab>^(TI[GC]...) (KNES) ([0-3][0-9])([0-2][0-9])([0-5][0-9]) <tab>FILE<tab>-close /realtime4/sat/satraw/(\3:yyyy)(\3:mm)(\3:dd)\2\4\5.\1 # WMO<tab>^(TI[GC]...) (KNES) ([0-3][0-9])([0-2][0-9])([0-5][0-9]) <tab>EXEC<tab>/home/ldm/etc/sat-none.sh (\3:yyyy)(\3:mm)(\3:dd)\2\4\5.\1 Note that due to the limitations of our support-email system, I've used "<tab>" to indicate the tab character.
