The else statement is an optional statement that is normally used in an "if-else" or "if-else if-else" construction. The way the else statement works is that, if the condition associated with either the "if" or the "else if" control structure is false, program control automatically goes...

An if statement in its most basic form: if some_command; then echo "some_command success: exit status = 0" else echo "some_command failure: exit status = $?" fi In Unix sh and Bash, [ is an actual command (a shell built-in). You can get help on it by using:...

Excel functions generally calculate all values in their range – whether the cells are hidden or not. This is practical, as it does not change the final result. However, sometimes that is exactly what you want. If so, SUBTOTAL can help in Excel: Multiple calculations react to any… ...
