从java小程序检查程序是否安装在linux机器上 [英] Check if a program is installed on a linux machine from a java applet

问题描述

我需要能够检查客户端计算机上是否安装了某个软件以及安装在何处，以便启动它.我发现了以下三篇关于如何在 Windows 和 Mac 上执行此操作的帖子，但我似乎无法弄清楚 Linux，因为没有注册表.有谁知道如何在 Linux 上做到这一点?

Hi I need to be able to check if a certain software is installed on the clients computer and where, in order to launch it. I found the following three posts as to how to do so on Windows and Mac but I can't seem to figure it out for Linux as there is no registry. Does any one know how this can be done on Linux?

适用于 Windows 和 Mac 的类似帖子:

任何帮助将不胜感激:)

any help would be greatly appreciated :)

推荐答案

使用

which file

命令来查明软件是否安装在路径中.如果没有任何结果，那么你可以做一个

command to find out if the software is installed in the path. If that comes up with nothing then you could do a

find ./ -name "file"

还要检查他们的本地 bin 或 .bin，如果它不包含在路径中.

Also check their local bin or .bin if its not included in the path.
