Perderabo, one more time, thanks for your help. And thank you very much for the documentation, I appreciate when someone replys with some good information backing up what they do. This is cool stuff, I learn one new thing every day about unix in general.

Hi matrixmadhan. Thanks again. I dont understand at all your statemnet about 'blocking on a read', could you please ellaborate more on that ?
say,
when login program spawns the shell,
untill we enter any commands to the shell, the interpretor waits indefinitely
called as the shell is blocking on a read !!!

same as opening a file and reading and writing to it,
to quit from the interpretor you give exit or Ctrl-D which is interpreted as -1 which fails the read from the shell, and shell process terminates.
