代码:

if: [color=blue]if COMMANDS; then COMMANDS; [ elif COMMANDS; then COMMANDS; ]... [ else COMMANDS; ] fi[/color]
The if COMMANDS are executed.  If the exit status is zero, then the then
COMMANDS are executed.  Otherwise, each of the elif COMMANDS are executed
in turn, and if the exit status is zero, the corresponding then COMMANDS
are executed and the if command completes.  Otherwise, the else COMMANDS
are executed, if present.  The exit status is the exit status of the last
command executed, or zero if no condition tested true.
