如何查找rpm方式安裝的軟件路徑

首先要申明一下which java是定位不到安裝路徑的。which java定位到的是java程序的執行路徑。網上的資料都是人雲亦雲，完全不去思考。那么怎么定位到java的安裝路徑呢？下面我們來看看例子吧,如下所示：

[root@localhost ~]# java -version

 

java version "1.7.0_65"

 

OpenJDK Runtime Environment (rhel-2.5.1.2.el6_5-x86_64 u65-b17)

 

OpenJDK 64-Bit Server VM (build 24.65-b04, mixed mode)

 

[root@localhost ~]# which java

 

/usr/bin/java

 

[root@localhost ~]# ls -lrt /usr/bin/java

 

lrwxrwxrwx. 1 root root 22 Aug 17 15:12 /usr/bin/java -> /etc/alternatives/java

 

[root@localhost ~]# ls -lrt /etc/alternatives/java

 

lrwxrwxrwx. 1 root root 46 Aug 17 15:12 /etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java

 

[root@localhost ~]#

 

[root@localhost ~]# cd /usr/lib/jvm

 

[root@localhost jvm]# ls
