sort 語法

Windows 2000，XP，及更高版本的語法

SORT [/R] [/+n] [/M kilobytes] [/L locale] [/REC recordbytes] [[drive1:][path1]filename1] [/T 
[drive2:][path2]] [/O [drive3:][path3]filename3]

/+n	指定字符號n，以開始每個比較。例如，/ + 3表示每次比較應從每行的第3個字符開始。少于n個字符的行將在其他行之前進行排序。默認情況下，比較從每行的第一個字符開始。
/L[OCALE] locale	用指定的語言環境覆蓋系統默認語言環境。“ C”語言環境產生最快的整理順序，并且是目前唯一的選擇。排序始終不區分大小寫。
/M[EMORY] kilobytes	指定用于排序的主內存量（以千字節為單位）。內存大小始終被限制為至少160 KB。如果指定了內存大小，則無論有多少主內存可用，都會使用精確的數量進行排序。通常，不指定內存大小即可達到最佳性能。默認情況下，如果排序符合默認的最大內存大小，則排序將一次性完成（無臨時文件）。否則，將分兩次進行排序（將部分排序的數據存儲在臨時文件中），以便用于排序和合并的內存量相等。如果輸入和輸出均為文件，則默認的最大內存大小為可用主內存的90％，否則為主內存的45％。
/REC[ORD_MAXIMUM] characters	指定記錄中的最大字符數（默認4096，最大65535）。
/R[EVERSE]	顛倒排序順序；也就是說，將Z排序為A，然后將9排序為0。
[drive1:][path1]filename1	指定要排序的文件。如果未指定，則對標準輸入進行排序。指定輸入文件比重定向與標準輸入相同的文件要快。
/T[EMPORARY] [drive2:][path2]	指定用于存放排序工作存儲的目錄路徑，以防數據不適合主內存。默認為使用臨時系統目錄。
/O[UTPUT] [drive3:][path3]filename3	指定存儲排序后的輸入的文件。如果未指定，則將數據寫入標準輸出。指定輸出文件比將標準輸出重定向到相同文件要快。

MS-DOS，Windows 95，98，ME，和 NT 語法

對輸入進行排序，并將結果寫入屏幕，文件或其他設備。

SORT [/R] [/+n] [[drive1:][path1]filename1] [> [drive2:][path2]filename2] [command |] SORT [/R] 
[/+n] [> [drive2:][path2]filename2]

/R	顛倒排序順序；也就是說，將Z排序為A，然后將9排序為0。
/+n	根據第n列中的字符對文件進行排序。
[drive1:][path1]filename1	指定要排序的文件
[drive2:][path2]filename2	指定要存儲排序后的輸入的文件。
command	指定要對其輸出進行排序的命令。

Windows 2000, XP, and later syntax

SORT [/R] [/+n] [/M kilobytes] [/L locale] [/REC recordbytes] [[drive1:][path1]filename1] [/T 
[drive2:][path2]] [/O [drive3:][path3]filename3]

/+n	Specifies the character number, n, to begin each comparison. For example, /+3 indicates that each comparison should begin at the 3rd character in each line. Lines with fewer than n characters collate before other lines. Comparisons start at the first character in each line by default.
/L[OCALE] locale	Overrides the system default locale with the one specified. The "C" locale yields the fastest collating sequence and is currently the only alternative. The sort is always case insensitive.
/M[EMORY] kilobytes	Specifies the amount of main memory to use for the sort, in kilobytes. The memory size is always constrained to be a minimum of 160 kilobytes. If the memory size is specified the exact amount will be used for the sort, regardless of how much main memory is available. The best performance is usually achieved by not specifying a memory size. By default, sort is done in one pass (no temporary file) if the sort fits in the default maximum memory size. Otherwise, the sort is done in two passes (with the partially sorted data being stored in a temporary file) such that the amounts of memory used for both the sort and merge passes are equal. The default maximum memory size is 90% of available main memory if both the input and output are files, and 45% of main memory otherwise.
/REC[ORD_MAXIMUM] characters	Specifies the maximum number of characters in a record (default 4096, maximum 65535).
/R[EVERSE]	Reverses the sort order; that is, sorts Z to A, then 9 to 0.
[drive1:][path1]filename1	Specifies the file to be sorted. If not specified, the standard input is sorted. Specifying the input file is faster than redirecting the same file as standard input.
/T[EMPORARY] [drive2:][path2]	Specifies the path of the directory to hold the sort's working storage, in case the data does not fit in main memory. The default is to use the temporary system directory.
/O[UTPUT] [drive3:][path3]filename3	Specifies the file where the sorted input is to be stored. If not specified, the data is written to the standard output. Specifying the output file is faster than redirecting standard output to the same file.

MS-DOS, Windows 95, 98, ME, and NT syntax

Sorts input and writes results to the screen, a file, or another device.

SORT [/R] [/+n] [[drive1:][path1]filename1] [> [drive2:][path2]filename2] [command |] SORT [/R] 
[/+n] [> [drive2:][path2]filename2]

/R	Reverses the sort order; that is, sorts Z to A, then 9 to 0.
/+n	Sorts the file according to characters in column n.
[drive1:][path1]filename1	Specifies file(s) to be sorted
[drive2:][path2]filename2	Specifies a file where the sorted input is to be stored.
command	Specifies a command whose output is to be sorted.

sort 示例

sort test.txt

此命令將顯示test.txt中文本的排序結果。

sort test.txt /o output.txt

下一條命令將排序后的結果存儲在output.txt文件中。

sort test.txt

This command would display the sorted results of the text in test.txt.

sort test.txt /o output.txt

This next command takes the sorted results and stores them in the output.txt file.

如果要對文件列表進行排序，則可以將dir命令與sort命令一起使用。例如，“ dir / on”對按字母順序列出的文件進行排序。有關更多示例和選項，請參見dir命令頁面。
