A suspended job may be continued with the fg command. There is also a bg which causes a suspended job to resume execution in the background. The jobs command displays information about jobs running in the background or suspended. The default signal is a terminate signal which will end most processes. The format of the command is kill pid where pid is the integer PID of the process.
Some processes are stubborn or are capable of catching the terminate signal.
To completely stop a process which ignores the terminate signal, use -9 as an option to the kill command. Other signals or interrupts may be specified as arguments. For more information, enter man kill.
