Merge two files on awk/shell
Hi,
i have two files like these:
FILE 1
Code:
00:0f:35:1b:0c:00  1402691094.750049000 00:0f:35:1b:0c:00  1402691087.474893000
44:d3:ca:fd:a2:08 1402691091.865127000 
30:e4:db:c1:df:de  1402691090.192464000

FILE 2_
Code:
00:0F:35 Cisco Systems, Inc
30:E4:DB Cisco Systems, Inc


I need a file 3, that is the result of merge two files(with awk or shell),
and if in file1 there is the first column on file 2(00:0F:35 or 30:E4:DB)
, add the name of the mac (Cisco Systems, Inc) on file 3 with this output:
Code:
00:0f:35:1b:0c:00 Cisco Systems, Inc 1402691094.750049000 00:0f:35:1b:0c:00 Cisco Systems, Inc 1402691087.474893000
44:d3:ca:fd:a2:08 1402691091.865127000 
 30:e4:db:c1:df:de Cisco Systems, Inc 1402691090.192464000

Thanks a lot

I have proved with some like this:
Code:
'NR==FNR {h[$1] = $2; next} {print $1,$2,$3,h[$1]}' file2 file1 > file3

but it doesnt work

Mod Comment edit by bakunin: again, please use CODE-tags! Furthermore, please provide complete commands, not arbitrary snippets! One could guess you are referring to an awk program, but it might help to remove all doubt and specify what you use, no?

Please use code tags as required by forum rules!

Above can't work as it would require different field separators. What ARE the FS of those files?

The first field of the fiel 1 es the first column(for example 00:0f:35:1b:0c:00)
and we need to merge with the first field of file 2 that is like 00:0F:35

That did NOT answer the question. If you use the default FS (space, <TAB>), field 2 in your file 2 is "Cisco" - that's part of why your script fails.
And, your written spec doesn't match your samples - in there, field 3 will be used for the match as well.
Howsoever, based on what we know so far, try
Code:
awk '
NR==FNR         {X = tolower($1)
                 sub ("^" $1 FS, "")
                 h[X] = $0
                 next
                }
                {X = $1
                 sub (/:[^:]*:[^:]*:[^:]*$/, "", X)
                 if (X in h) $1 = $1 FS h[X]
                }
1
