Wesley, We received the following NAM 218 product: Jul 18 20:14:52 notifyme[20472] INFO: 259276 20180718194035.741 CONDUIT 027 data/nccf/com/nam/prod/nam.20180718/nam.t18z.awip1202.tm00.grib2 !grib2/ncep/NAM_84/#000/201807181800F002/OMEG/700 hPa PRES! 000027 This product won't match your regular expression pattern: ^(data/nccf/com/nam.*awip12) !(.*)! because of the space in the pattern after the "awip12". Because you're only using the first parenthetical sub-string, you could probably use a simpler pattern like "^(data/nccf/com/nam.*awip12)". If you must match on the stuff between the exclamation points, then try a pattern like "^(data/nccf/com/nam.*awip12).*!.*!" You can test regular expression patterns with the LDM's regex(1) utility: $ regex -s 'data/nccf/com/nam/prod/nam.20180718/nam.t18z.awip1202.tm00.grib2 !grib2/ncep/NAM_84/#000/201807181800F002/OMEG/700 hPa PRES! 000027' '^(data/nccf/com/nam.*awip12) !(.*)!' no match $ regex -s 'data/nccf/com/nam/prod/nam.20180718/nam.t18z.awip1202.tm00.grib2 !grib2/ncep/NAM_84/#000/201807181800F002/OMEG/700 hPa PRES! 000027' '^(data/nccf/com/nam.*awip12)' match $ regex -s 'data/nccf/com/nam/prod/nam.20180718/nam.t18z.awip1202.tm00.grib2 !grib2/ncep/NAM_84/#000/201807181800F002/OMEG/700 hPa PRES! 000027' '^(data/nccf/com/nam.*awip12).*!.*!' match Regards, Steve Emmerson Ticket Details =================== Ticket ID: ERJ-637034 Department: Support LDM Priority: Normal Status: Closed =================== NOTE: All email exchanges with Unidata User Support are recorded in the Unidata inquiry tracking system and then made publicly available through the web.
