    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.

    --retry
    keep trying to open a file even if it is inaccessible when tail starts or if it becomes inaccessible later; useful when following by name, i.e., with --follow=name
    -c, --bytes=N
    output the last N bytes
    -f, --follow[={name|descriptor}]
    output appended data as the file grows; -f, --follow, and --follow=descriptor are equivalent
    -F
    same as --follow=name --retry
    -n, --lines=N
    output the last N lines, instead of the last 10
    --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)
    --pid=PID
    with -f, terminate after process ID, PID dies
    -q, --quiet, --silent
    never output headers giving file names
    -s, --sleep-interval=S
    with -f, sleep for approximately S seconds (default 1.0) between iterations.
    -v, --verbose
    always output headers giving file names
    --help
    display this help and exit
    --version
    output version information and exit

    If the first character of N (the number of bytes or lines) is a `+', print beginning with the Nth item from the start of each file, otherwise, print the last N items in the file. N may have a multiplier suffix: b 512, k 1024, m 1024*1024.

    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 by reopening it periodically to see if it has been removed and recreated by some other program.
