11 bytes added, 21 March
INVESTIGATION 3: exit AND break STATEMENTS
# Save your editing session and exit the text editor (eg. with vi: press '''ESC''', then type ''':x''' followed by '''ENTER''').<br><br>
# '''Add execute permissions''' for this Bash shell script.<br><br>
# Issue the following command (without arguments):<br><span style="color:blue;font-weight:bold;font-family:courier;">./exit.bash</span><br><br>What did you notice?<br><br>Since there are no arguments, the test within the running shell script returns FALSE, <br>then an '''error message''' with feedback of how to properly issue the shell script with an argument <br>and then terminates the Bash shell script.<br><br>The symbol &gt;&amp;2 redirects standard output from the USAGE message as standard error making like a real error message.<br><br>
