"Linux command-File management class" Split command

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 helloHello, World1Hello, World2Hello, World3Hello, World4Hello, 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:

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 10 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 10 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.
