NAME

       sort - sort lines of text files

SYNOPSIS

       sort [OPTION]... [FILE]...
       sort [OPTION]... --files0-from=F

DESCRIPTION

       Write sorted concatenation of all FILE(s) to standard output.

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

       -b, --ignore-leading-blanks
              ignore leading blanks

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

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

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

       -i, --ignore-nonprinting
              consider only printable characters

       -M, --month-sort
              compare (unknown) < `JAN' < ... < `DEC'

       -h, --human-numeric-sort
              compare human readable numbers (e.g., 2K 1G)

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

       -R, --random-sort
              sort by random hash of keys

       --random-source=FILE
              get random bytes from FILE

       -r, --reverse
              reverse the result of comparisons

       --sort=WORD
              sort according to WORD: general-numeric -g, human-numeric -h, month -M, numeric -n,
              random -R, version -V

       -V, --version-sort
              natural sort of (version) numbers within text

       Other options:

       --batch-size=NMERGE
              merge at most NMERGE inputs at once; for more use temp files

       -c, --check, --check=diagnose-first
              check for sorted input; do not sort

       -C, --check=quiet, --check=silent
              like -c, but do not report first bad line

       --compress-program=PROG
              compress temporaries with PROG; decompress them with PROG -d

       --debug
              annotate  the  part  of the line used to sort, and warn about questionable usage to
              stderr

       --files0-from=F
              read input from the files specified by NUL-terminated names in file F; If  F  is  -
              then read names from standard input

       -k, --key=POS1[,POS2]
              start  a  key  at  POS1  (origin 1), end it at POS2 (default end of line).  See POS
              syntax below

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

       -o, --output=FILE
              write result to FILE instead of standard output

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

       -S, --buffer-size=SIZE
              use SIZE for main memory buffer

       -t, --field-separator=SEP
              use SEP instead of non-blank to blank transition

       -T, --temporary-directory=DIR
              use DIR for temporaries, not $TMPDIR or /tmp;  multiple  options  specify  multiple
              directories

       --parallel=N
              change the number of sorts run concurrently to N

       -u, --unique
              with  -c,  check for strict ordering; without -c, output only the first of an equal
              run

       -z, --zero-terminated
              end lines with 0 byte, not newline

       --help display this help and exit

       --version
              output version information and exit

       POS is F[.C][OPTS], where F is the field number and C the character position in the field;
       both  are  origin 1.  If neither -t nor -b is in effect, characters in a field are counted
       from the beginning of the  preceding  whitespace.   OPTS  is  one  or  more  single-letter
       ordering  options,  which  override  global  ordering  options for that key.  If no key is
       given, use the entire line as the key.

       SIZE may be followed by the following multiplicative suffixes: % 1% of memory, b 1, K 1024
       (default), and so on for M, G, T, P, E, Z, Y.

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

       ***  WARNING *** The locale specified by the environment affects sort order.  Set LC_ALL=C
       to get the traditional sort order that uses native byte values.
