The text file testfile to conduct the second cut-off point cut in two, use the following command:
csplit testfile 2
testfile file reads as follows:
$ cat testfile #查看testfile 文件内容 hello Linux! Linux is a free Unix-type operating system. This is a Linux testfile! Linux
Use csplit command, the output results are as follows:
$ csplit testfile 2 13 #xx00文件字符个数 76 #xx01文件字符个数
The first row is the first file xx00 number of characters, the same second behavior of the second file is the number of characters xx01. Meanwhile, in the same directory testfile will generate two files, the file names are xx00, xx01, xx00 contents as follows:
$ cat xx00 #查看分割后的xx00文件内容 hello Linux! #testfile文件第1行的内容
xx01 contents as follows:
$ cat xx01 #查看分割后的xx01文件内容 Linux is a free Unix-type operating system. #testfile文件第2行以后的内容 This is a Linux testfile! Linux
