#Bash 的 basename 命令

basename OPTION... NAME [SUFFIX]

功能

从文件路径中去除目录和后缀。

类型

可执行文件（/usr/bin/basename），属于 coreutils。

参数

OPTION 选项：
- -a, --multiple - 输入多个文件名参数，而不是要删除的后缀
- -s, --suffix=SUFFIX - 删除后缀的 SUFFIX
- -z, --zero - 以空字符（\0）作为行的结尾，而不是换行符（\n）
- --help - 显示帮助
- --version - 显示版本
NAME - 文件路径；不要求文件存在
SUFFIX - 要删除的后缀；同 -s 选项

#示例

单个文件

$ basename /path/to/file.txt        # 去除目录
rgb.txt
$ basename /path/to/file.txt .txt   # 去除目录和后缀

多个文件

$ basename -a /path/to/file1.txt /path/to/file2.txt             # 去除目录
file1.txt
file2.txt
$ basename -s .txt -a /path/to/file1.txt /path/to/file2.txt     # 去除目录和后缀
file1
file2

-s 选项参数必须在 -a 选项之前，否则 -a 会将 -s 和 .txt 也视为两个文件路径参数
