sort [OPTION]... [FILE]...
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options
too. Ordering options:
ignore leading blanks
consider only blanks and alphanumeric characters
fold lower case to upper case characters
compare according to general numerical value
consider only printable characters
compare (unknown) < 'JAN' < ... < 'DEC'
compare according to string numerical value
reverse the result of comparisons
check whether input is sorted; do not sort
start a key at POS1, end it at POS2 (origin 1)
merge already sorted files; do not sort
write result to FILE instead of standard output
stabilize sort by disabling last-resort comparison
use SIZE for main memory buffer
--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.

order. Set LC_ALL=C to get the traditional sort order that uses native
