问题描述

您好我需要能够检查是否安装客户端计算机并在上某个软件，才能启动它。我发现下面的三个职位至于如何做到这一点在Windows和Mac，但我似乎无法推测出来的Linux，因为没有注册。是否有任何人知道这是如何能够在Linux上做什么？

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?

推荐答案

使用了

which file

命令，以找出是否该软件安装路径。如果什么也没有出现，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"

另外，请查阅当地的垃圾桶或.BIN如果不在路径包括在内。

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