Another shell script exercise.

UNIX shell script exercise

Below is a shell script that combines system variables ($LOGNAME), system command (uname –a), and UNIX fundamental command (ls).

The sleep is the shell command. It pauses the output for the specified number of seconds.

#!/bin/sh tell UNIX to go directly to the Bourne shell.

# by itself is used to comment out the line.

Be careful with the ` symbol; it is known as the grave accent and it is located above the tab key. It tells UNIX to execute the command within the enclosing grave symbols (e.g.  `    `)

#!/bin/sh

# written by a student

echo   "Hello $LOGNAME, it is nice talking to you."

echo  "Your present working directory is `pwd`"

echo   "You are working on a machine called `uname -a`"

sleep 5

echo  "Here is the listing of your files"

ls

echo   "Bye for now $LOGNAME. The time is `date+%T`!"
