{{Admon/tip|Bash Shell Scripting Tips:|<br><ul><li>'''The case statement:'''<br><br>The case statement is a control-flow statement that works in a similar way as the if-elif-else statement (but is more concise). This statement presents scenerios or "cases" based on values or regular expressions (not ranges of values like if-elif-else statements). After action(s) are taken for a particular scenerio (or "case"), a break statement (''';;''') is used to "break-out" of the statement (and not perform other actions). A default case (*) is also used to catch exceptions.<br><br><u>'''Example Examples (try in shell script):'''</u><br><br>read -p "pick a door (1 or 2): " pick<br>case $pick in<br>1) echo "You win a car!" ;;<br>2) echo "You win a bag of dirt!" ;;<br>*) echo "Not a valid entry"<br> exit 1 ;;<br>esac<br><br></li><li>'''The getopts function:'''<br><br></li></ul>x<br><br><ul><li>'''<u>Example of getopts function</u>'''<br><br></li></ul>}}
