NAME  SYNOPSIS  DESCRIPTION  Arguments:  OPTIONS 

NAME

sort − sort

SYNOPSIS

sort [OPTION]... [FILE]...

DESCRIPTION

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

Arguments:

[files]...

OPTIONS

−−help

Print help information.

−−version

Print version information.

−−sort <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>...]

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 <key>

sort by a key

−t, −−field−separator <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_FILE>

read input from the files specified by NUL−terminated NUL_FILE

−−debug

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

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.
