First linux command you learn.. "man"
Code:
# man man

man(1)                                                                  man(1)

NAME
       man - format and display the on-line manual pages

SYNOPSIS
       man [-acdfFhkKtwW] [--path] [-m system] [-p string] [-C config_file] [-M pathlist] [-P pager] [-B browser] [-H htmlpager] [-S section_list] [sec-
       tion] name ...

DESCRIPTION
       man formats and displays the on-line manual pages.  If you specify section, man only looks in that section of the manual.  name is  normally  the
       name  of the manual page, which is typically the name of a command, function, or file.  However, if name contains a slash (/) then man interprets
       it as a file specification, so that you can do man ./foo.5 or even man /cd/foo/bar.1.gz.

       See below for a description of where man looks for the manual page files.

ikon is trying to help you learn. Your requirements are vague, so this is sounds like classwork. We do not allow homework on the forums

Requirments Taken literally:
Code:
# this is the time now in hours minutes and seconds using the date command
date +%H:%M:%S
sleep [ you put something here ]
echo "5 minutes left"
sleep [ something else here ]
exit

Now learn how to use the sleep command to wait 25 minutes, echo "5 minutes left"; then sleep 5 minutes, then exit.

i realy appreciate all of your help(Akon,Jim ) .Yes it's a kind of coursework and im trying to finish it with your help to give me a direction to do some functionality, that's why i asked about a way to caculate the time(it's the final part of my job). I'm reading now the man manual for date and sleep and will start with the code you gave me Akon. I hope i can do it right.
