表示行の並び替えを行うConstruction
$ sort [option] [file]
Option
-m : 複数のファイルに対応する
-b : 先頭の空白を無視する（trimみたいな機能）
-f : 大文字、小文字を区別せずに判断する
-d : アルファベット、数字、スペースを対象にする
-n : 先頭の記号と数値を数値として判断する
-r : 逆ソートする
-u : ユニーク表示（同一行がある場合は最初の１行のみ表示する）
-o [file]:結果をfileに書き込む
-k [pos1,pos2...] : keyを元にソートする
Sample
# file1とfile2を混ぜてソートする
$ sort -m file1 file2
# 大文字とみなさないソート
$ sort -t : -k 2,2 file1
# 大文字とみなすソート
＄ sort -f -t : -k 2,2 file1
Caution
メモリが16Mbを超えないように注意しよう。Discription
Write sorted concatenation of all FILE(s) to standard output.
Mandatory arguments to long options are mandatory for short options too. Ordering
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 POS2 (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
use SIZE for main memory buffer
-t, --field-separator=SEP
use SEP instead of non-blank to blank transition
-T, --temporary-directory=DIR
use DIR for temporaries, not $TMPDIR or /tmp; multiple options specify multiple
directories
-u, --unique
with -c, check for strict ordering; without -c, output only the first of an
equal run
-z, --zero-terminated
end lines with 0 byte, not newline
--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. 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.
