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:

1--

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~

程序代码:
@echo off
@setlocal
rem Copyright (C):  2001, 2002  Earnie Boyd
rem   mailto:earnie@users. This file is part of Minimal SYStem
rem   http://www.
rem
rem File:        msys.bat
rem Revision:        2.0
rem Revision Date:  April 17th, 2002

rem ember to set the "Start in:" field of the shortcut.
rem A value similar to C:\msys\1.0\bin is what the "Start in:" field needs
rem to represent.

rem this should let run MSYS shell on x64
if "%PROCESSOR_ARCHITECTURE%" == "AMD64" (
  SET COMSPEC=%WINDIR%\SysWOW64\cmd.exe
)

rem ember value of GOTO: is used to know recursion has happened.
if "%1" == "GOTO:" goto %2

rem ember  only uses the first eight characters of the label.
set OS_VERSION="NT"
goto _WindowsNT

rem ember that we only execute here if we are in  OS_VERSION="9x"

if "x%COMSPEC%" == "x" set COMSPEC= %COMSPEC% /e:4096 /c %0 GOTO: _Resume %0 %1 %2 %3 %4 %5 %6 %7 %8 %9
goto EOF


rem ember that we execute here if we recursed.
:_Resume
for %%F in (1 2 3) do shift

rem ember that we get here even in if "x%MSYSTEM%" == "x" set MSYSTEM=MINGW32
if "%1" == "MSYS" set MSYSTEM=MSYS

if NOT "x%DISPLAY%" == "x" set DISPLAY=

rem We here assume old behavior, to make sure that older platforms can still use
rem this batch file to start their MSys environment.
set BIN=""

if EXIST bin\nul set BIN=bin\
if EXIST %BIN%bash.exe goto startbash
if EXIST %BIN%rxvt.exe goto startrxvt


rem If we're not on win9x type OSs, lets try a little better at finding bash/rxvt
if "win%OS_VERSION%"=="win9x" goto failed
set BIN="%~dp0bin\"
if EXIST %BIN%bash.exe goto startbash
if EXIST %BIN%rxvt.exe goto startrxvt


:failed
echo Cannot find the rxvt.exe or bash.exe binary -- aborting.
pause
rem exit 1
rem we skip using exit 1 here, since it will close the console you were working on
rem which probably isn't what you wanted. If the bat file was run from a shortcut
rem the window will still close, like you would expect it to. Sorry, you cant test
rem for exit values anymore, but hey, you can just un-rem the line above then! :-)
goto EOF

rem If you don't want to use rxvt then rename the file rxvt.exe to something
rem else.  Then bash.exe will be used instead.
:startrxvt

rem Setup the default colors for rxvt.
if "x%MSYSBGCOLOR%" == "x" set MSYSBGCOLOR=White
if "x%MSYSFGCOLOR%" == "x" set MSYSFGCOLOR=Black
if "x%MINGW32BGCOLOR%" == "x" set MINGW32BGCOLOR=LightYellow
if "x%MINGW32FGCOLOR%" == "x" set MINGW32FGCOLOR=Navy
if "%MSYSTEM%" == "MSYS" set BGCOLOR=%MSYSBGCOLOR%
if "%MSYSTEM%" == "MSYS" set FGCOLOR=%MSYSFGCOLOR%
if "%MSYSTEM%" == "MINGW32" set BGCOLOR=%MINGW32BGCOLOR%
if "%MSYSTEM%" == "MINGW32" set FGCOLOR=%MINGW32FGCOLOR%

start %COMSPEC% /c %BIN%rxvt -backspacekey  -sl 2500 -fg %FGCOLOR% -bg %BGCOLOR% -sr -fn Courier-12 -tn msys -geometry 80x25 -e /bin/bash --login -i 

exit

:startbash

call %COMSPEC% /c %BIN%bash --login -i 

rem cmd默认情况用执行msys命令不支持中文--把这个的快捷方式复制到运行文件目录下--上面语句可以通过重定向向文本写入程序,等于间接执行msysgit命令(使用者注)

:EOF

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?

2--
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~

最后如果觉得该内容已经超出本版块的讨论范围的,请版主及时转移该帖子到合理的版块,再次感谢~

那个获取上级路径及名称的运行结果如下:
程序代码:
当前正在运行的批处理文件所在路径:E:\bzpp\temp
当前目录是:E:\bzpp\temp
当前正在运行的批处理文件所在路径:E:\bzpp\temp\
当前的盘符及路径:E:\bzpp\temp\
当前的盘符及路径的短文件名格式:E:\bzpp\temp\
取当前文件的上级目录的名称
j k
请按任意键继续. . . 


这正确吗?
百度一个“批处理命令详解”,大概就看的明白吧。以前做过一些简单的批处理,其中也有处理参数和变量的,根据自己需求,对照百度很容易完成的。

回复 2楼 xzlxzlxzl
嗯,小白阶段~目前主要用来处理一些简单的gcc程序~就是感觉自己有太多不会了……感觉网上的个个都是大牛就我那么小白~

看了一下,那个代码是"正确"的,不过不具备多少可移植性~那只是个样例~自己要用要改改set那里的路径~哇……我竟然没有留意我的D盘多了个abc文件夹………………~
