Windows批处理文件有哪些不太为人所知,但很重要和有用的特性?

指南:

每个答案一个特征 给出特性的简短描述和示例,而不仅仅是文档链接 将答案限制在本地功能,即不需要额外的软件,如Windows资源包

澄清:这里我们指的是由cmd.exe处理的脚本,这是WinNT变体的默认值。

(请参见:Windows批处理文件:.bat vs .cmd?)

FIND作为grep的替代品。 我用find给自己黑了个电话簿。非常有用:

@echo off
:begin
set /p term=Enter query: 
type phonebookfile.txt |find /i "%term%"
if %errorlevel% == 0 GOTO :choose
echo No entry found
set /p new_entry=Add new entry: 
echo %new_entry% >> phonebookfile.txt 
:choose
set /p action=(q)uit, (n)ew query or (e)dit? [q] 
if "%action%"=="n" GOTO anfang
if "%action%"=="e" (
    notepad phonebookfile.txt
    goto :choose
)

非常快速有效。

去:eof纸板

我在脚本的末尾添加了“goto:eof”,作为存放代码片段的方便空间。这样我就可以快速复制/粘贴到这个区域,而不需要注释/取消注释。

goto :eof
:: code scraps
call this.bat
call that.bat
set TS=%DATE:~10%%DATE:~4,2%%DATE:~7,2%-%TIME:~0,2%%TIME:~3,2%%TIME:~6%%
for /R C:\temp\ %%G in (*.bak) DO del %%G

支持正则表达式的Findstr:

findstr "^[0-9].*" c:\windows\system32\drivers\etc\hosts

我使用它们作为常用目录的快捷方式。 一个名为“sandbox.bat”的示例文件,它位于我的PATH目录中

EXPLORER "C:\Documents and Settings\myusername\Desktop\sandbox"

调用脚本只需WIN+R—>沙盒

There is also the EDLIN command. While it may be an old bastard tool once used for line-based text editing, the fact that it's controllable from the command line makes it rather useful for batch scripting, mostly because, just like any other case you'd be using EDLIN, it's the only tool available. After all, EDLIN is not a tool you would ordinarily want to use for text editing, unless you are somewhat masochistic. To quote Tim Patterson (the fellow who wrote it): "I was aghast when I heard that IBM was using it and not throwing it out the window."

注意:EDLIN将老式的EOF (1A)标记添加到它编辑的文件中。如果需要删除它们,可能必须使用DEBUG。
