This article mainly introduces the use of linux sort command to sort files and output, the article is very detailed, has a certain reference value, interested friends must read it!

The sort command is very useful in Linux, which sorts the files and outputs the sorted results standard. The sort command can get input either from a specific file or from stdin.

Syntax format: sort [parameters] [file]

Commonly used parameters: coach

-b ignores the space characters that begin at the beginning of each line-c checks whether the file has been sorted in order-d, processes English letters, numbers and space characters, ignores other characters when sorting-f, treats lowercase letters as uppercase letters-I, except for ASCII characters between 040 and 176 Ignore other characters-m to merge files with several sort numbers-M sorts the first three letters according to the abbreviation of the month-n sort by numeric size-o stores the sorted results in the established file-r sorts in reverse order-t specifies the field separator used for sorting-k specifies the field to be sorted

Reference example

Sort compares each line of the file / text as a unit. The principle of comparison is to compare each other from the first character to the back, compare them according to the ASCII code value in turn, and finally output them in ascending order:

[root@linuxcool ~] # cat sort.txt

CC:30:3.3

DD:40:4.4
