在 Bash 下批量更改文件扩展名
galeki post @ 2007年10月03日 12:24AM in Bash Tips with tags: bash 扩展名 批量

如果我想把当前目录下的所有扩展名为 cpp 的文件，改成扩展名为 c 的文件，要怎么办？ 用 shell 编程可以很容易的解决这个问题：

 1. #!/bin/bash
 2. for old in *.cpp
 3. do
 4. mv $old `basename $old .cpp`.c
 5. done

特别解释一下第4行的 basename 这个命令，basename 返回文件完整路径中的文件名部分，例如： 
# basename /home/galeki/html/index.html
index.html

你也可以在参数中给出文件的扩展名，这样 basename 只会返回文件名除去扩展名的部分：
# basename /home/galeki/html/index.html .html
index

 也可以把上面的程序修改一下，让它可以根据参数处理不同的扩展名：

 1. #!/bin/bash
 2. for old in *.$1
 3. do
 4. mv $old `basename $old .$1`.$2
 5. done

 把上面这段代码存成 rn ( rename 的缩写 )，如果你想把当前目录下的所有文件的扩展名从 jpg 改成 png ，那么，只要执行： rn jpg png ，即可。
