Conditionally perform a command.
Syntax if list; then list; [ elif list; then list; ] ... [ else list; ] fi
The if list is executed. If its exit status is zero, the then list is executed.
Otherwise, each elif list is executed in turn, and if its exit status is zero, the corresponding then list is executed and the command completes. Otherwise, the else list is executed, if present.
The exit status is the exit status of the last command executed, or zero if no condition tested true.)
if is a bash builtin command.
