NAME¶runlevel - Print previous and current SysV runlevel
DESCRIPTION¶runlevel prints the previous and current SysV runlevel if they are known. The two runlevel characters are separated by a single space character. If a runlevel cannot be determined, N is printed instead. If neither can be determined, the word "unknown" is printed. Unless overridden in the environment, this will check the utmp database for recent runlevel changes.
OPTIONS¶The following option is understood: --help
Prints a short help text and exits.
EXIT STATUS¶If one or both runlevels could be determined, 0 is returned, a non-zero failure code otherwise.
If $RUNLEVEL is set, runlevel will print this value as current runlevel and ignore utmp.$PREVLEVEL
If $PREVLEVEL is set runlevel will print this value as previous runlevel and ignore utmp.
The utmp database runlevel reads the previous and current runlevel from.
NOTES¶This is a legacy command available for compatibility only. It should not be used anymore, as the concept of runlevels is obsolete.
