 sort - sort lines of text files
 

SYNOPSIS

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

DESCRIPTION

 Write sorted concatenation of all FILE(s) to standard outュ
 put.
 
 +POS1 [-POS2]
 start a key at POS1, end it *before* POS2 (obsolesュ
 cent) field numbers and character offsets are numュ
 bered starting with zero (contrast with the -k
 option)
 
 -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
 -b
 
 -i consider only [040円-0176円] 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
 -b
 
 -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ュ
 tion
 
 use DIRECTORY for temporary files, not $TMPDIR or
 /tmp
 
 -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
 -print0
 
 --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 counted from one
 with -k, from zero with the obsolescent form. OPTS is
 made up of one or more of Mbdfinr; this effectively disュ
 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.
