AND and OR lists are sequences of one of more pipelines separated by the && and || control operators,
respectively. AND and OR lists are executed with left associativity. An AND list has the form
command1 && command2
command2 is executed if, and only if, command1 returns an exit status of zero.
An OR list has the form
command1 || command2
command2 is executed if and only if command1 returns a non-zero exit status. The return status of AND
and OR lists is the exit status of the last command executed in the list.
make executes commands in the makefile to update one or more target names, where name is typically a
program. If no -f option is present, make will look for the makefiles GNUmakefile, makefile, and
Makefile, in that order.
