Mkill - Send processes making a active mount point busy a signal SYNOPSIS
mkill [-SIG] [-u] /mnt1 [/mnt2...] mkill [-l] DESCRIPTION
mkill determines all active mount points from /proc/mounts and compares this with the specified mount points. Then mkill seeks for pro- cesses making this mount points busy. For this search only the links found in /proc/<pid>/ are used to avoid hangs on files provided by network file systems like nfs(5). The default signal is SIGTERM for termination. If a mount point is not active, that is that it is not found in /proc/mounts, mkill will do exactly nothing. OPTIONS
-<SIG> Signals can be specified either by name (e.g. -HUP, -SIGHUP) or by number (e.g. -1). -0 The special signal 0 force mkill to list all processes making the specified mount point busy. -u Perform a lazy umount on the specified mount points before sending the signal SIGTERM or SIGKILL. -l List all known signals. EXAMPLES
mkill -TERM /var This will terminate all processes accessing a seperate /var partition. mkill -HUP /dev/pts All processes using a pseudo-terminal slave will hangup. RETURN VALUE
Always success which is that zero is returned. SEE ALSO
