PROGRAM:

NAME


tail - output the last part of files

SYNOPSIS


tail [OPTION]... [FILE]...

DESCRIPTION


Print the last 10 lines of each FILE to standard output. With more than one FILE, precede
each with a header giving the file name.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.

-c, --bytes=[+]NUM
output the last NUM bytes; or use -c +NUM to output starting with byte NUM of each
file

-f, --follow[={name|descriptor}]
output appended data as the file grows;

an absent option argument means 'descriptor'

-F same as --follow=name --retry

-n, --lines=[+]NUM
output the last NUM lines, instead of the last 10; or use -n +NUM to output
starting with line NUM

--max-unchanged-stats=N
with --follow=name, reopen a FILE which has not

changed size after N (default 5) iterations to see if it has been unlinked or
renamed (this is the usual case of rotated log files); with inotify, this option is
rarely useful

--pid=PID
with -f, terminate after process ID, PID dies

-q, --quiet, --silent
never output headers giving file names

--retry
keep trying to open a file if it is inaccessible

-s, --sleep-interval=N
with -f, sleep for approximately N seconds (default 1.0) between iterations; with
inotify and --pid=P, check process P at least once every N seconds

-v, --verbose
always output headers giving file names

-z, --zero-terminated
line delimiter is NUL, not newline

--help display this help and exit

--version
output version information and exit

NUM may have a multiplier suffix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB
1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.

With --follow (-f), tail defaults to following the file descriptor, which means that even
if a tail'ed file is renamed, tail will continue to track its end. This default behavior
is not desirable when you really want to track the actual name of the file, not the file
descriptor (e.g., log rotation). Use --follow=name in that case. That causes tail to
track the named file in a way that accommodates renaming, removal and creation.
