我有bat文件(settings.bat).i会将这个bat文件提供给我的client.my客户端没有任何技术知识。如果我的客户端点击我的bat文件,我的java程序将运行。这是我的bat文件数据。
set path = "java installation path"
java addition
java sutraction
pause
在上面的bat set path中我安装了我的java软件(/ jre / bin)。
现在我的要求是,我必须从执行这个bat.can的机器上获取java安装的路径(... / jre / bin),任何人都可以帮助我。
答案 0 :(得分:0)
path
,甚至不要覆盖set
commands set "path=%path%;%myAppPath%"
暂时。请改为添加您的文件夹:set "path=%myAppPath%;%path%"
或"
;
=
引文,path %path%;myAppPath%
周围没有空格,以避免所有path
command中的任何前导和尾随空格。where
command,因此您可以使用"%myAppPath%\myApp"
。cmd
。但是如何让知道未知计算机上的程序的完整路径?让我们使用Deploying the JRE on Windows,查看从==> where /F notepad.exe
"C:\Windows\System32\notepad.exe"
"C:\Windows\notepad.exe"
==> where /F pspad.exe
INFO: Could not find files for the given pattern(s).
==> where /F pspad.exe 2>NUL
==> where /R "%ProgramFiles%" /F pspad.exe 2>NUL
==> where /R "%ProgramFiles(x86)%" /F pspad.exe 2>NUL
"C:\Program Files (x86)\PSPad editor\PSPad.exe"
窗口粘贴的示例:
==> set "myAppPath="
==> for /F "delims=" %G in ('where /F notepad.exe 2^>NUL') do @set "myAppPath=%~dpG"
==> set myAppPath
myAppPath=C:\Windows\
将我的应用程序的路径存储到变量(最后一次出现):
==> set "myAppPath="
==> for /F "delims=" %G in ('where /F notepad.exe 2^>NUL') do @if not defined myAppPath set "myAppPath=%~dpG"
==> set myAppPath
myAppPath=C:\Windows\System32\
(第一次出现):
@ECHO OFF
SETLOCAL EnableExtensions
set "myApp=%~1"
if not defined myApp set "myApp=java.exe"
set "myAppPath="
rem search in %path% environment variable
for /F "delims=" %%G in ('
where /F %myApp% 2^>NUL
') do set "myAppPath=%%~dpG" & goto :no1
:no1
rem search in %ProgramFiles% folder recursively
if not defined myAppPath for /F "delims=" %%G in ('
where /R "%ProgramFiles%" /F %myApp% 2^>NUL
') do if not defined myAppPath set "myAppPath=%%~dpG" & goto :no2
:no2
rem search in %ProgramFiles(x86)% folder recursively
if not defined myAppPath (
if defined ProgramFiles^(x86^) for /F "delims=" %%G in ('
where /R "%ProgramFiles(x86)%" /F %myApp% 2^>NUL
') do set "myAppPath=%%~dpG" & goto :no3
)
:no3
rem search in %SystemDrive%\ disk recursively
if not defined myAppPath for /F "delims=" %%G in ('
where /R %SystemDrive%\ /F %myApp% 2^>NUL
') do set "myAppPath=%%~dpG" & goto :no4
:no4
rem populate results
if defined myAppPath (echo could run "%myAppPath%%myapp%") else (
echo '%myapp%' not found in %SystemDrive%\ disk
)
将它们放在一个批处理脚本中:
==> 34039382.bat notepad
could run "C:\Windows\System32\notepad"
==> 34039382.bat iexplore.exe
could run "C:\Program Files\Internet Explorer\iexplore.exe"
==> 34039382.bat pspad.exe
could run "C:\Program Files (x86)\PSPad editor\pspad.exe"
==> 34039382.bat psexec.exe
could run "C:\Utils\Sysinternals\psexec.exe"
==> 34039382.bat
'java.exe' not found in C:\ disk
<强>输出强>:
java.exe
这篇oracle文章http://sphinxsearch.com/docs/current.html#fields声明Java安装程序会将java.exe
复制到系统目录中:
安装了
bin
个可执行文件的两个副本。一份是在 JRE的C:\windows\system
目录。第二个副本放在任一个中C:\winnt\system32
或java.exe
,具体取决于系统。 由于它在系统目录中的位置,这是第二个副本-rw-r-----+ 1 599076 599076 3371531 Dec 1 08:15 engine.log -rw-r-----+ 1 599076 599076 86949 Dec 2 08:16 engine.log
可以从的任何目录位置启动而不需要 给出完整的路径。
