Hi Eric,

Thanks for your prompt reply. 

I am referring to the manual -> 'Sams teach yourself shell in 24 hours', which is authored by Sriranga Veeraraghavan. 

Following is example potrayed in that manual:

If multiple files are specified, the contents of the files are concatenated in the output, but line numbering is restarted at 1 for each file. As an illustration, the following command,

$ cat -b fruits users

produces the output

1 Fruit Price/lbs Quantity
2 Banana $0.89 100
3 Peach $0.79 65
4 Kiwi $1.50 22
5 Pineapple $1.29 35
6 Apple $0.99 78

1 ranga
2 vathsa
3 amma

So, this was what led me think this is a bug in cat command for RHEL 5.7, because this guy must have experimented it on the RHEL machine before printing it in the manual. 

Regards
Mayank

Thanks for the report.  What manual was this?  I don't see anything
implying that in the 'info cat' section of the official coreutils
manual, so this is likely a bug in downstream documentation rather than
an actual problem in coreutils.  But without knowing a URL of the faulty
documentation, we can't tell you where to redirect your report.

coreutils' cat has never restarted numbering with new files. Maybe you
were thinking of 'sed --separate'?  At any rate, we're probably going to
close this report as not a bug, although I've left it open for a bit
longer in case you can tell us more details about what led you to
believe that renumbering from 1 was expected, in case there is something
we need to improve in coreutils' documentation.
