Split command

Function Description: Cut the file.

Syntax: Split [--help][--version][-< rows >][-b < bytes >][-c < bytes >][-l < rows >][files to be cut [output file name]

Additional note: Split can cut the file into smaller files, with a preset of 1000 lines cut into a small file.

Parameters

-< lines > or-l< > Specify how many lines to cut into a small file.

-B < bytes > Specify how many words you want to cut into a small file. Support Unit: M,k

The-c < byte > is similar to the-B parameter, but maintains the integrity of each line as much as possible when cutting.

-a specifies the suffix length of the output file name, which defaults to 2 (Aa,ab ...)

-d Specifies the suffix of the output file name to replace with a number

--help display Help.

--version Displays version information.

[Output file name] Sets the file's predecessor file name after cutting, and split automatically adds a number to the pre-file name.
