The s6-linux-init-shutdown program

s6-linux-init-shutdown triggers the system shutdown procedure.

Interface

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

Supplementary options

These options are supported by s6-linux-init-shutdown but are not part of the LSB-3.0.0 shutdown specification.

• -R tmpfsdir : assume that the root-only boot-time tmpfs has been mounted on tmpfsdir. Default is /run. The shutdown script created by a s6-linux-init-maker invocation automatically execs into s6-linux-init-shutdown with the correct -R option.

Notes

• The s6-linux-init-shutdown binary is not meant to be called directly by administrators. Instead, its purpose is to be used in a shutdown script created by s6-linux-init-maker.
