NAME(名称)

sort - 对文本文件的行排序

SYNOPSIS(总览)

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

DESCRIPTION(描述)

将排序好的所有文件串写到标准输出上。

+POS1 [-POS2]: 从关键字POS1开始,到POS2*之前*结束(快过时了) 字段数和字符偏移量都从零开始计数(与-k选项比较)
-b: 忽略排序字段或关键字中开头的空格
-c: 检查是否指定文件已经排序好了,不排序.
-d: 在关键字中只考虑[a-zA-Z0-9]字符.
-f: 将关键字中的小写字母折合成大写字母.
-g: 按照通常的数字值顺序作比较,暗含-b
-i: 在关键字中只考虑[\040-\0176]字符.
-k POS1[,POS2]: 从关键字POS1开始,*到*POS2结束. 字段数和字符偏移量都从1开始计数(与基于零的+POS格式作比较)
-l: 按照当前环境排序.
-m: 合并已经排序好的文件,不排序.
-M: 按(未知的)<`JAN'<...<`DEC'的顺序比较,暗含-b
-n: 按照字符串的数值顺序比较,暗含-b
-o FILE: 将结果写入FILE而不是标准输出.
-r: 颠倒比较的结果.
-s: 通过屏蔽最后的再分类比较来稳定排序.
-t SEP: 使用SEP来替代空格的转换non-.
-T DIRECTORY: 使用DIRECTORY作为临时文件,而不是$TMPDIR或者/tmp
-u: 如果有-c,则按严格的顺序进行检查; 如果有-m,则只输出相等顺序的第一个.
-z: 以0字节结束行,而不是使用换行符,这是为了找到-print0
--help: 显示帮助并退出.
--version: 输出版本信息并退出.

POS为F[.C][OPTS],这里的F指的是字段数,而C为字段中的字符位置,这在-k中是从开始计数的,而在过时的格式中是从零开始的.OPTS可由一个或多个Mbdfinr组成;这有效地屏蔽了对于那个关键字的全局-Mbdfinr设置.如果没有指定关键字,则使用整行作为关键字.如果没有FILE,或者FILE是-,则从标准输入读取.

NAME

sort - sort lines of text files

SYNOPSIS

sort [OPTION]... [FILE]...

DESCRIPTION

Write sorted concatenation of all FILE(s) to standard output.

Ordering options:

Mandatory arguments to long options are mandatory for short options too.

-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 POS 2 (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.
