| - | ====== Gentle Introduction ====== | ||
| - | |||
| - | ===== Frequently Asked Questions aka FAQ ===== | ||
| - | |||
| - | ==== How do I see all processes? ==== | ||
| - | * ''ps ax'' | ||
| - | * ''top'' | ||
| - | |||
| - | Note that the output display of top is constrained by the size of the terminal/console, so if there are more processes than lines, top will not show all processes. | ||
| - | |||
| - | ==== Why do some processes have a negative PID? ==== | ||
| - | The processes have a negative PID because they are part of the kernel. | ||
| - | |||
| - | ==== What do the names of the operating system processes mean and what is their function? ==== | ||
| - | === Kernel "processes" === | ||
| - | | **name** | **full name** | **purpose** | | ||
| - | | asyncm | | ||
| - | | idle | | ||
| - | | clock | | ||
| - | | system | | ||
| - | | kernel | | ||
| - | |||
| - | === System processes: servers === | ||
| - | | **name** | **full name** | **purpose** | | ||
| - | | pm | process mananger | | ||
| - | | vfs | virtual file system | | ||
| - | | rs | reincarnation server | monitor other system processes and re-start them as needed, see ''man service'' | | ||
| - | | ds | data store server | | ||
| - | | vm | virtual memory server | | ||
| - | | pfs | pipe file system | | ||
| - | | sched | scheduler | | ||
| - | | init | | grandparent of all processes, see ''man init'' | | ||
| - | | procfs | | | ||
| - | | mfs | Minix file system | | ||
| - | | is | information server | for debug dumps | | ||
| - | | inet | Internet Protocol server | | | ||
| - | | ipc | inter-process communication | | | ||
| - | |||
| - | === System processes: device drivers === | ||
| - | | **name** | **full name** | **purpose** | | ||
| - | | log | log driver | buffers log output | | ||
| - | | memory | memory driver | | ||
| - | | tty | terminal driver (historical origin of name is "teletype") | console and keyboard driver | | ||
| - | | pci | | ||
| - | | floppy | | ||
| - | | at_wini | AT disk driver | | ||
| - | | random | | ||
| - | | printer | | ||
| - | |||
| - | ==== Why can't I refresh the Ethernet driver? When I type "service refresh e1000" I see "no such process" in response. ==== | ||
| - | The Ethernet driver can have multiple instances and its label is the name of the driver followed by an underscore followed by a number which represents the instance number (starting at 0). | ||
| - | |||
| - | For instance, when I enter ''ps ax'', I see "/usr/sbin/e1000 instance=0", so the label is "e1000_0". I can also see the labels of the services by hitting Shift + F6 at the Minix console. See [[:UsersGuide:CommandLineInterface]] for more of these useful function keys. See ''man service'' for details on the service command. | ||
| - | |||
| - | So, the proper answer is ''service refresh e1000_0''. | ||
