The write command should do what you want - have a look at the man page with `man write`.

Thx for giving the command but I need to know the comlpete working of the 'write' command ie what 'c' functions will it make use of. Iam trying to understand how a msg moves from one system to another using ethernet. Where can I get all the detailed info about the headers appended and functions used in completing the task.

Taking each part of your post...

- Use `man write` or `man talk` to get the complete workings of the command;
- Use the strace command to see what the command is doing, e.g. `strace write user [ttyname]`;
- Use ethereal to capture the packets to see what traffic is actually sent.

It may be that talk or write don't do what you need - hence the man page reference...
