Obviously, all of these processes will need to stop using the open files before the file system can be unmounted. If you re not sure where a particular command is running from, or on which file system its data files are stored, you can also use lsof to check open files by passing the PID on the command line. First, you need to identify a PID by using the ps command:

Command Reference
The following commands are commonly used to manage processes.
The following table summarizes the main options used with ps.
Option Description Lists most frequently requested processes List all processes Lists processes in scheduler format Lists all processes Prints comprehensive process information Prints process information on a group basis for a single group Prints process information on a group basis for a list of groups Includes SID and PGID in printout Prints complete process information Displays LWP details Lists process details for list of specified processes Lists the CPU ID to which a process is bound Lists session leaders Lists all processes associated with a specific terminal Lists all processes for a specific user

kill
The following table summarizes the main signals used to communicate with processes using kill.
Signal SIGHUP SIGINT SIGQUIT SIGILL SIGTRAP SIGABRT SIGEMT SIGFPE SIGKILL SIGBUS SIGSEGV SIGSYS SIGPIPE SIGALRM SIGTERM Code 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Action Exit Exit Core Core Core Core Core Core Exit Core Core Core Exit Exit Exit Description Hangup Interrupt Quit Illegal instruction Trace Abort Emulation trap Arithmetic exception Killed Bus error Segmentation fault Bad system call Broken pipe Alarm clock Terminate
pgrep
The pgrep command is used to search for a list of processes whose names match a pattern specified on the command line. The command returns a list of corresponding PIDs. This list can then be piped to another command, such as kill, to perform some action on the processes or send them a signal. For example, to kill all processes associated with the name java, the following command would be used:
