TAILF(1) User Commands TAILF(1)NAME
tailf - follow the growth of a log file
tailf [OPTION] file
tailf will print out the last 10 lines of a file and then wait for the file to grow. It is similar to tail -f but does not access the file
when it is not growing. This has the side effect of not updating the access time for the file, so a filesystem flush does not occur peri-
odically when no log activity is happening.
tailf is extremely useful for monitoring log files on a laptop when logging is infrequent and the user desires that the hard disk spin down
to conserve battery life.
Mandatory arguments to long options are mandatory for short options too.
-n, --lines=N, -N
output the last N lines, instead of the last 10.
Output version information and exit.
Display help and exit.

SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)NAME
switch_root - switch to another filesystem as the root of the mount tree
switch_root newroot init [arg...]
switch_root moves already mounted /proc, /dev and /sys to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS -h, --help
show help and exit
show version number and exit
switch_root returns 0 on success and 1 on failure.
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR
