DESCRIPTION
Display sorted concatenation of all FILE(s). With no FILE, or when FILE is -, read standard input.

OPTIONS

--help
    Print help information.

--version
    Print version information.

--sort
    [possible values: general-numeric, human-numeric, month, numeric, version, random]

-h, --human-numeric-sort
    compare according to human readable sizes, eg 1M > 100k

-M, --month-sort
    compare according to month name abbreviation

-n, --numeric-sort
    compare according to string numerical value

-g, --general-numeric-sort
    compare according to string general numerical value

-V, --version-sort
    Sort by SemVer version number, eg 1.12.2 > 1.1.2

-R, --random-sort
    shuffle in random order

-d, --dictionary-order
    consider only blanks and alphanumeric characters

-m, --merge
    merge already sorted files; do not sort

-c, --check
    check for sorted input; do not sort
    [possible values: silent, quiet, diagnose-first]

-C, --check-silent
    exit successfully if the given file is already sorted, and exit with status 1 otherwise.

-f, --ignore-case
    fold lower case to upper case characters

-i, --ignore-nonprinting
    ignore nonprinting characters

-b, --ignore-leading-blanks
    ignore leading blanks when finding sort keys in each line

-o, --output=FILENAME
    write output to FILENAME instead of stdout

-r, --reverse
    reverse the output

-s, --stable
    stabilize sort by disabling last-resort comparison

-u, --unique
    output only the first of an equal run

-k, --key
    sort by a key

-t, --field-separator
    custom separator for -k

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

--parallel=NUM_THREADS
    change the number of threads running concurrently to NUM_THREADS

-S, --buffer-size=SIZE
    sets the maximum SIZE of each segment in number of sorted items

-T, --temporary-directory=DIR
    use DIR for temporaries, not $TMPDIR or /tmp

--compress-program=PROG
    compress temporary files with PROG, decompress with PROG -d; PROG has to take input from stdin and output to stdout

--batch-size=N_MERGE
    Merge at most N_MERGE inputs at once.

--files0-from=NUL_FILES
    read input from the files specified by NUL-terminated NUL_FILES

--debug
    underline the parts of the line that are actually used for sorting

[files]

EXTRA
The key format is FIELD[.CHAR][OPTIONS][,FIELD[.CHAR]][OPTIONS]. Fields by default are separated by the first whitespace after a non-whitespace character. Use -t to specify a custom separator. In the default case, whitespace is appended at the beginning of each field. Custom separators however are not included in fields. FIELD and CHAR both start at 1 (i.e. they are 1-indexed). If there is no end specified after a comma, the end will be the end of the line. If CHAR is set 0, it means the end of the field. CHAR defaults to 1 for the start position and to 0 for the end position. Valid options are: MbdfhnRrV. They override the global options for this key.
