Linux Split command detailed

Original: http://m.jb51.net/article/73632.htm

The Linux split command is used to divide a file into several, which splits large files into smaller files, which, by default, are cut into a small file per 1000 lines, with the basic syntax of split [--help][--version][-< rows >][- b < bytes >][-c < bytes >][-l < number of lines >][file to be cut [output file name].

command function : Cut files, cut files in units of behavior or in bytes

command Syntax :

Split [–help][–version]

Split [-< number of rows >][-l < rows;] [file to be cut] [output FILENAME]
, in number of rows

Split [-B < bytes >][-c < bytes;] [file to be cut] [output file name], in bytes

The output file name refers to a file that is then prefixed with the cut.

1. Cutting files in a behavioral unit

First create a 5-line file Hello,

#cat Hello
Hello, World1.
Hello, World2.
Hello, World3.
Hello, World4.
Hello, World5.

Use the command:

#split-2 Hello split1_

The split command cuts the file in two units, each consisting of a new file, and 5 rows with three files, each with the following names:

Split1_aa, Split1_ab, Split_ac

2. Cut in bytes

Or the file hello, using the command ls-l hello can see the size of the file is 65 bytes, cut the file with 10 bytes, there will be 7 files

Use the-B command first, as follows:

#split-B Hello split2_

There are 7 files cut out,

Split2_aa, Split2_ab, Split2_ac, Split2_ad, Split2_ae, Split2_af, Split2_ag

The following uses the-c parameter, as follows:

#split-C-Hello split3_

Cut out 10 files and output the following with the Ls-l command:

Although the file is also cut in bytes, but the-C parameter will try to maintain the integrity of each line, that is, a row has 13 bytes, then it will be cut into two files, a 10 byte, a 3 byte, and the-B parameter will accumulate 8 bytes to the next line to fill 10 bytes and then cut, so-b parameter only 7 files, The-c parameter has 10 files.
