In a Linux environment, how do you see which packages are dependent on which package?

Requirements Description:

Today check the host of a software Ghostscript, ready to delete, first look at the software depends on which software,

And what software depends on it?

Operation Process :

1. See what software This software depends on (RPM query)

[Email protected] ~]# rpm-q Ghostscript#查看对应的rpm包.
Ghostscript-8.70-19.el6.x86_64
[Email protected] ~]# RPM-QR Ghostscript #R的意思就是requires就是依赖哪些软件包.

Note: The above query is a dependent package.

2. Use Yum to query for dependent programs

3. Check which software is dependent on the software (i.e. what software will be affected if I want to remove it)

[Email protected] ~]# rpm-q nfs-utils #查看这个软件是否安装. NFS-utils-1.2.3- Wu. El6.x86_64[[email protected]~]# rpm-e--test nfs-utils #通过--test to test the deletion to see if there is a dependency and if there are any that will prevent the deletion. The test can be deleted. error:failed Dependencies:nfs-utils >=1.2.1- Oneis 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 If the removal may have an impact on this program.[[Email protected]~]# rpm-e--test nfs-utilserror:failed Dependencies:nfs-utils >=1.2.1- Oneis needed by (installed) nfs-utils-lib-1.1.5-9. El6.x86_64[[email protected]~]# rpm-e--testgcc #测试删除gcc, there is no error, that is, there is no other place to rely on it, can be deleted.[[Email protected]~]# Rpm-qgcc #上面的--test did not really deleteGCC-4.4.7- One. el6.x86_64
