• 查看帮助：

basename --help

• 主要的使用方法如下：

Mandatory arguments to long options are mandatory for short options too.
  -a, --multiple       support multiple arguments and treat each as a NAME
  -s, --suffix=SUFFIX  remove a trailing SUFFIX
  -z, --zero           separate output with NUL rather than newline
      --help     display this help and exit
      --version  output version information and exit

Examples:
  basename /usr/bin/sort          -> "sort"
  basename include/stdio.h .h     -> "stdio"
  basename -s .h include/stdio.h  -> "stdio"
  basename -a any/str1 any/str2   -> "str1" followed by "str2"

• 我的测试命令和输出如下：

basename /home/zql/project/data/myTestdata/test2/123456.txt
123456.txt

basename /home/zql/project/data/myTestdata/test2/123456.txt .txt
123456
