sort (1)


       sort - sort lines of text files


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


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

       Ordering options:

       Mandatory  arguments  to  long  options are mandatory for short 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'

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

       -r, --reverse
              reverse the result of comparisons

       Other options:

       -c, --check
              check whether input is sorted; do not sort

       -k, --key=POS1[,POS2]
              start a key at POS1, end it at POS 2 (origin 1)

       -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
       -u, --unique
              with -c: check for strict ordering
              otherwise: output only the first of an equal run

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

       --help display this help and exit

              output version information and exit

       POS is F[.C][OPTS], where F is the field number  and  C  the  character
       position  in  the  field.   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.
