Find the difference in specific field
Hi All,

Seeking for your assistance to get the difference of field1 and field2 and output all the records if there's a difference. please see below scenario.

Code:
file1.txt
250|UPTREND FASHION DESIGN,CORP.|2016-04-04 09:36:13.991257
74|MAINSTREAM BUSINESS INC.|2016-04-04 09:36:13.991257
36|HOMEWORLD SHOPPING CORP.|2016-03-30 12:50:13.50646

file2.txt
250|UPTREND FASHION DESIGN,CORP.|2016-04-04 09:33:13.991257
74|MAINSTREAM BUSINESS INC.|2016-04-04 09:35:13.991257

Code:
 I tried this diff file1.txt file2.txt | grep "<" | awk '{for (i=2; i<NF; i++) printf $i " "; print $NF}' but the problem is it will check all the records, all i want is the field1 and field2 check only.

Please advise,

Thanks,

I already solve the problem using this code
Code:
awk 'NR==FNR {exclude[$1$2];next} !($1$2 in exclude)' file2.txt file1.txt

Thank you!

LEARN ABOUT SUSE

lzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
