File Parsing
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...

DIFF(1) General Commands Manual DIFF(1)
NAME
diff - print differences between two files
SYNOPSIS
diff [-c | -e | -C n] [-br]file1 file2
OPTIONS
-C n Produce output that contains n lines of context
-b Ignore white space when comparing
-c Produce output that contains three lines of context
-e Produce an ed-script to convert file1 into file2
-r Apply diff recursively to files and directories of
EXAMPLES
diff file1 file2 # Print differences between 2 files
diff -C 0 file1 file2
# Same as above
diff -C 3 file1 file2
# Output three lines of context with every
diff -c file1 file2 # Same
diff /etc /dev # Compares recursively the directories /etc and /dev
diff passwd /etc # Compares ./passwd to /etc/passwd
DESCRIPTION
the same name, when file1 and file2 are both directories" difference encountered"
Diff compares two files and generates a list of lines telling how the two files differ. Lines may not be longer than 128 characters. If
the two arguments on the command line are both directories, diff recursively steps through all subdirectories comparing files of the same
name. If a file name is found only in one directory, a diagnostic message is written to stdout. A file that is of either block special,
character special or FIFO special type, cannot be compared to any other file. On the other hand, if there is one directory and one file
given on the command line, diff tries to compare the file with the same name as file in the directory directory.
