dirname 有2种可能：
1，带相对路径，只能获取相对路径
2，带绝对路径，则可以获取完整的路径
一般这个基本是执行脚本，需要进入到当前脚本的目录中，或者相对这个脚本的相对路径中，所以一般用如下命令可以实现拿到当前脚本的路径
path=$(cd dirname $0;pwd)
echo “this is file path:”$path
this is file path:/home #输出结果
bashname 获取脚本的文件名
fullfile=basename $0
file=basename $0 .sh
echo "this is full file name:"
f
u

fullfile echo "this is file name:"
fullfileecho"thisisfilename:"file
this is full file name:checkpath.sh #输出结果
this is file name:checkpath #输出结果，一般用这种比较多，获取文件名，不带后缀
