如果要学写批处理命令和msysgit及命令?~
最近安装了mingw和gcc编译器,然后学用bat写msysgit命令对编译文件学件一件运行程序其中包括对编译文件的管理……一些简单的cmd命令还好,不过接触到一些msys的命令例如ls cut之类的就感觉自己小白一个了,就连最基础的语法也不会
主要有以下两点问题:

例如下面一段批处理代码是启动msysgit的,感觉自己现在能力有限看不懂具体内容,虽然有rem注释参考

再例如找了个获取相对路径的以及列出文件上级路径及名称的:
程序代码：
@echo off
setlocal EnableDelayedExpansion
echo 当前正在运行的批处理文件所在路径：!cd!
@echo off
echo 当前目录是：%cd%
@echo off
:: set "abc=%cd%"
echo 当前正在运行的批处理文件所在路径：%~dp0
@echo off
echo 当前的盘符及路径:%~dp0
echo 当前的盘符及路径的短文件名格式:%~sdp0
@echo 取当前文件的上级目录的名称
set a=D:\abc\def ghi\j k\lmn.bat
for %%a in ("%a%") do (
set ok=%%~dpa
for /f "delims=" %%b in ("!ok:~0,-1!") do (
echo %%~nb
)
)
pause
bat命令上网搜搜我可以学学,不过如果要学得详细一点应该参考哪些书籍或者有没有什么好的建议?

msysgit命令上网搜过好像讲得简略,几乎没有什么涉及到具体操作的内容或者还是我能力问题搜不到具体的学习方法……
就算有也是直接是应用代码几乎找不到学习语法,如果要系统学习相关内容应该参考哪些书籍或者有哪些好的建议,拜谢了
