sort - sort lines of text files
../src/sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard out
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

-f fold lower case to upper case characters in keys
-g compare according to general numerical value, imply

-l sort according to current locale
-m merge already sorted files, do not sort
-M compare (unknown) < `JAN' < ... < `DEC', imply -b

write result on FILE instead of standard output

--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.
