Hi Vgersh99,
thanks for the reply. Yes your assumption is correct. It should be dc1 instead of dlc1. Sorry for the typo error.
When i executed the awk script there was no matching output. The body starting with NR==FNR works perfect by reading all the input records from the file1. I just verified using print $0
However i do not have any clue wrt the line ($2 SUBSEP $4 SUBSEP $6 SUBSEP $8 ) in f1. Could you please help me in deciphering this line as i am not much comfortable to awk.
Also please note that a record in file1 will not match a record in file2 on a one to one basis i.e.,the first record in file1 may match 100th record in file2 and the second record in file1 may match 40123th record in file2.
Again i thank you for sparing your time...
