Dear All Can you please do me favor and let me know how can I compare two files but not in line-by-line basis on my CentOS server ? I mean say row#1 in file1 has the same data as say row#5 in file2 , but the comm compares them in line-by-line basis that is not intended . It seems that the diff cannot do the job as well . Thank you in advance -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20091202/e25a234d/attachment-0004.html>
