I am using gedit to write my script and the language is bash shell

Write a script the will do the following

a)Take a command-line argument, a user's login name

b)Test to see if a command-line argument was provided

c)check to see if the user is in the /etc/passwd file

d)If the user is found the script will print "Found" "in the /etc/passwd file"

e)If not then the script will print "No such user on our system"
