The s6-linux-init-shutdown program

s6-linux-init-shutdown triggers the system shutdown procedure. It is normally invoked as /sbin/shutdown.

Interface

     s6-linux-init-shutdown [ -h | -p | -r | -k ] [ -a ] [ -t sec ] [ -f | -F ] time [ message ]
     s6-linux-init-shutdown -c [ message ]

• If the -c option is present, a pending shutdown is cancelled.
• Else, it triggers the shutdown procedure.
• It exits 0. The shutdown procedure happens asynchronously.

The s6-linux-init-shutdown program conforms to the LSB-3.0.0 shutdown interface.

Exit codes

• 0: shutdown procedure triggered.
• 100: wrong usage, or user does not have root privileges.
• 111: system call failed.

Notes

• The s6-linux-init-shutdown binary is not meant to be called directly by administrators. Instead, after a s6-linux-init-maker invocation, the bin/ subdirectory of the target will contain a shutdown symlink to s6-linux-init-shutdown. The bin/ subdirectory should be copied by the administrator into /sbin for full interface compatibility with sysvinit.
