runlevel: Check your current runlevel. Then change it
Today's commands are how you can check what runlevel your system is in and then change it.
Check the current runlevel:
[[email protected] tmp]# runlevel N 5
Change the current runlevel:
[[email protected] tmp]# init <new_level>
The run levels in Unix/Linux are used to define what state init (the parent of all processes) is in. Each distribution of Unix/Linux has different definitions of what run levels starts what processes.
Usually you can find the different definitions in
/etc/inittab below is the one from a fedora box.
# Default runlevel. The runlevels used are: # 0 - halt (Do NOT set initdefault to this) # 1 - Single user mode # 2 - Multiuser, without NFS (The same as 3, if you do not have networking) # 3 - Full multiuser mode # 4 - unused # 5 - X11 # 6 - reboot (Do NOT set initdefault to this)
