Premature EOF
How to check for a premature EOF in a regular file in a shell/perl script?
I want to check if I have received a complete file or not.

Thanks,
Rahul.

Why not use checksum ?

here is one more,

have a trailer record for each of the file you are receiving
(just including a single line is not going to affect the receiving file size)
trailer record to contain no of records in the file

existence of trailer indicates complete file transfer

But How?
Vino,

How to use checksum? When i type checksum on my command prompt, it says command not found. I am using a Sun Solaris 5.8

Madhan,

I am using wget to grab the webpage running on Windows server. What the following command does is create a file with the webpage URL name in my current directory.

wget -nv -o /tmp/wget.csv.log -t 5 -w 10 http://vpcmsa06/qos/1HRScsv.asp

Now, Without doing any modification to this file i.e http://vpcmsa06/qos/1HRScsv.asp, I want to check if it has a premature EOF.

Any advise would be helpful.

Thanks,
Rahul.

i understand that the modification to the existing asp file would not be possible

instead, is it possible to idenitfy the start and end of the file with markers
just as we do in html pages ?

(ex only)
<HTML>
</HTML>

but i am not sure how far this could be made use of ....
its just an example or kind of way proceeding with that.

No Specific Markers
These files will not have any specific start or end markers and hence I am unable to do a premature EOF check.

Thanks,
Rahul.

I will still stick to Vino. If you have a way to get the checksums of the file from the place where you are getting it, then you can run the command cksum on the received file, and then match the two. cksum is one of the surest way to convince that the file received is complete and exactly the same as one that is sent.
