       sort - sort lines of text files


       ../src/sort [OPTION]... [FILE]...


       Write sorted concatenation of all FILE(s) to standard out­
       +POS1 [-POS2]
              start a key at POS1, end it *before* POS2 (obsoles­
              cent)  field numbers and character offsets are num­
              bered starting with  zero  (contrast  with  the  -k
       -b     ignore leading blanks in sort fields or keys
       -c     check if given files already sorted, do not sort
       -d     consider only [a-zA-Z0-9 ] characters in keys
       -f     fold lower case to upper case characters in keys
       -g     compare according to general numerical value, imply
       -i     consider only [\040-\0176] characters in keys
       -k POS1[,POS2]
              start a key at POS1, end it *at* POS2 field numbers
              and  character  offsets  are numbered starting with
              one (contrast with zero-based +POS form)
       -l     sort according to current locale
       -m     merge already sorted files, do not sort
       -M     compare (unknown) < `JAN' < ... < `DEC', imply -b
       -n     compare according to string numerical value,  imply
       -o FILE
              write result on FILE instead of standard output
       -r     reverse the result of comparisons
       -s     stabilize sort by disabling last resort comparison
       -t SEP use SEParator instead of non- to whitespace transi­
              use DIRECTORY for temporary files, not  $TMPDIR  or
       -u     with  -c,  check for strict ordering; with -m, only
              output the first of an equal sequence
       -z     end lines  with  0  byte,  not  newline,  for  find
       --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,  both  counted  from  one
       with  -k,  from  zero  with the obsolescent form.  OPTS is
       made up of one or more of Mbdfinr; this  effectively  dis­
       ables global -Mbdfinr settings for that key.  If no key is
       given, use the entire line as the key.  With no  FILE,  or
       when FILE is -, read standard input.
