Utility for check sum of file

[ManjulaMadhu]

Hi,

sorry guys. this question is totally off the forum. I am tempted to post it here as I am assured of getting a reply.
Here's my query:

Does anyone know about a utility which can output the checksum of a file (I mean add up all the characters/spaces/numbers ..in the file ..using some internal funky logic of its own ) . In addition it will be good if it can also give the file size and other details of the file.

My input will be somthing like : utility <filename> It has to give an output of a number.

Comparing the source and destination file sizes for this seems to be a good idea. but , sometimes its deceptive. I need to know even if there is a change in a space between the two files.

Thanks,

Not entirely off - topic. I use &quot;sum&quot; on Solaris to checksum files between production and standby instance:

NAME
sum - print checksum and block count for a file

SYNOPSIS
sum [-r] [file...]

e.g.
$ sum control.ctl
21182 491 control.ctl

exactly..icahn..

I am looking for something like this on Unix or ORacle.
