linux环境中,如何查看某个软件包,都依赖哪些软件包?被哪些软件包依赖?
需求描述:
今天查看主机上的一个软件ghostscript,准备删除,就先看下这个软件都依赖哪些软件,
然后呢被哪些软件依赖
操作过程:
1.查看这个软件依赖哪些软件(rpm方式查询)
[root@testvm02 ~]# rpm -q ghostscript #查看对应的rpm包.
ghostscript-8.70-19.el6.x86_64
[root@testvm02 ~]# rpm -qR ghostscript #R的意思就是requires就是依赖哪些软件包.
/bin/sh
/sbin/ldconfig
/sbin/ldconfig
config(ghostscript) = 8.70-19.el6
ghostscript-fonts

2.通过yum方式来查询依赖的程序
[root@testvm02 ~]# yum deplist ghostscript

3.查看这个软件被哪些软件依赖(即如果我要删除了会对哪些软件的运行有影响)
[root@testvm02 ~]# rpm -q nfs-utils #查看这个软件是否安装. nfs-utils-1.2.3-54.el6.x86_64 [root@testvm02 ~]# rpm -e --test nfs-utils #通过--test进行测试删除,查看是否有依赖关系,如果有会阻止删除.测试是否能够删除. error: Failed dependencies: nfs-utils >= 1.2.1-11 is needed by (installed) nfs-utils-lib-1.1.5-9.el6.x86_64 #有其他的软件包依赖这个软件包,如果删除可能对这个程序有影响. [root@testvm02 ~]# rpm -e --test nfs-utils error: Failed dependencies: nfs-utils >= 1.2.1-11 is needed by (installed) nfs-utils-lib-1.1.5-9.el6.x86_64 [root@testvm02 ~]# rpm -e --test gcc #测试删除gcc,没有报错,也就是没有别的地方依赖它,可以进行删除. [root@testvm02 ~]# rpm -q gcc #上面的--test并没有真正删除 gcc-4.4.7-11.el6.x86_64
[root@testvm02 ~]# rpm -e gcc #不带--test参数,进行真正的删除.
[root@testvm02 ~]# rpm -q gcc #再次查询没有这个gcc已经被删除掉了.
package gcc is not installed
