+# Split 切分文件
+
+当面临将一个大文件进行切分时，linux 的 split 命令是很好的选择。它包含多种参数，支持按行、大小进行切分。
+
+split 命令的语法如下：
+
+```sh
+split [--help][--version][-a ][-b][-C ][-d][-l ] <input file> <output file prefix>
+```
+
+## 按行数分割
+
+```sh
+split -l 300 <input file> <output file prefix>
+```
+
+加上 -d，使用数字后缀；加上 --verbose，显示分割进度：
+
+```sh
+split --verbose -l50000 -d <input file> <output file prefix>
+```
+
+## 按字节大小分割
+
+```sh
+split -b 10m <input file> <output file prefix>
+```
+
+## 合并文件
+
+参见 [《Cat 合并文件》](../Cat/Cat_合并文件.md)
