rust-tail1

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 flags are mandatory for short flags too.

Usage

tail [{-c | --bytes}] [{-f | --follow}] [{-n | --lines}] [--pid] [{-q | --quiet}] [{-s | --sleep-interval}] [--max-unchanged-stats] [{-v | --verbose}] [{-z | --zero-terminated}] [--use-polling] [--retry] [-F] [{-h | --help}] [{-V | --version}] [files]

Overview

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 flags are mandatory for short flags too.

Options

-c, --bytes: Number of bytes to print

-f, --follow

Print the file as it grows

[possible values: descriptor, name]

-n, --lines: Number of lines to print

--pid=PID: With -f, terminate after process ID, PID dies

-q, --quiet: Never output headers giving file names

-s, --sleep-interval=N: Number of seconds to sleep between polling the file when running with -f

--max-unchanged-stats=N: 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); This option is meaningful only when polling (i.e., with --use-polling) and when --follow=name

-v, --verbose: Always output headers giving file names

-z, --zero-terminated: Line delimiter is NUL, not newline

--use-polling: Disable 'inotify' support and use polling instead

--retry: Keep trying to open a file if it is inaccessible

-F: Same as --follow=name --retry

-h, --help: Print help

-V, --version: Print version
