一、window 环境脚本语法

1. if 语句

Usage 1：

bat脚本中字符串不用加“”号，如果添加后则许两重双引号才能相等

set computername=xyz
set dropLoc=machine-abc
if "%computername%" == "xyz" (
  set dropLoc=machine-xyz
)
echo %dropLoc%

Usage 2：

goto debug表示调用debug函数

rem 这是注释
set DEBUG_OPTS=
if ""%1"" == ""debug"" (
   set DEBUG_OPTS= -Xloggc:../logs/gc.log -verbose:gc -XX:+PrintGCDetails -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../logs 
   goto debug
)

springboot启动脚本

echo off

set APP_NAME=springboot-vue.jar
set CONFIG= -Dlogging.path=../logs -Dlogging.config=../config/log4j2.xml -Dspring.config.location=../config/application.yml 

set DEBUG_OPTS=
if ""%1"" == ""debug"" (
   set DEBUG_OPTS= -Xloggc:../logs/gc.log -verbose:gc -XX:+PrintGCDetails -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../logs 
   goto debug
)

set JMX_OPTS=
if ""%1"" == ""jmx"" (
   set JMX_OPTS= -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9888 -Dcom.sun.management.jmxremote.ssl=FALSE -Dcom.sun.management.jmxremote.authenticate=FALSE 
   goto jmx
)

echo "Starting the %APP_NAME%"
java -Xms512m -Xmx512m -server %DEBUG_OPTS% %JMX_OPTS% %CONFIG% -jar ../lib/%APP_NAME%
goto end

:debug
echo "debug"
java -Xms512m -Xmx512m -server %DEBUG_OPTS% %CONFIG% -jar ../lib/%APP_NAME%
goto end

:jmx
java -Xms512m -Xmx512m -server %JMX_OPTS% %CONFIG% -jar ../lib/%APP_NAME%
goto end

:end
pause

bat处理替换xml文件中的字符

@echo off

set filename=mylove.xml
setlocal DisableDelayedExpansion
SET MyVar=../logs
set oldStr=logs
(for /F "delims=" %%G in (%filename%) do (
   set "str=%%G"
   setlocal EnableDelayedExpansion
   set "strTrim={x}!str!{x}"
   if "!strTrim!"=="{x}{x}" (
      CALL :BlankLine
   ) ELSE (
      set "str=!str:%oldStr%=%MyVar%!"
      IF "!str!"=="" (
         CALL :BlankLine
      ) ELSE (      
         set "strTrim=!strTrim:   ={x}!"
         set "strTrim=!strTrim: ={x}!"
         set "strTrim=!strTrim:{x}{x}={x}!"
         set "strTrim=!strTrim:{x}{x}={x}!"
         :: I had to repeat the set "strTrim=!strTrim:{x}{x}={x}!" several times to get rid of all combinations of blanks - I could also have edited the template, of course...
         IF "!strTrim!"=="{x}" (CALL :BlankLine) ELSE (ECHO !str!)
      )
   )
   endlocal
)) > filename.xml
#move "%filename%.tmp" "%filename%"
goto :eof

:BlankLine
ECHO(
goto :eof

batch中条用powershell下载文件

PowerShell.exe curl https://search.maven.org/remotecontent?filepath=kg/apc/jmeter-plugins-manager/0.20/jmeter-plugins-manager-0.20.jar -O jmeter-plugins-manager-0.20.jar

-O是指定下载路径

获取某个目录下文件

@echo off 
::  
set num=0
setlocal enabledelayedexpansion 
set conf_dir=../config
for /R "%conf_dir%" %%s in (*) do (
  ::set str=!str!,%conf_dir%/%%~nxs 
  set /a num+=1 
  IF !num! equ 1 (
    set str= !str!%conf_dir%/%%~nxs
  ) ELSE (
    set str= !str!,%conf_dir%/%%~nxs
  )
) 
echo %str%
pause

~nx表示不显示文件的路径名
