How to install lsblk on CentOS 5

Question

I'm more used to Debian so yum and CentOS is a little new to me.

Apparently, lsblk is not available on this system. I'm trying to install it via yum with no luck. I just get "nothing to do".

I updated the CentOS-Base.repo file and ran yum clean all. It still doesn't find the package.

What should be my next step?

Solution

It's in the following package. You can use this command to install it on CentOS 6+:

$ sudo yum install util-linux-ng

Example

$ lsblk 
NAME                        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0                          11:0    1 1024M  0 rom  
vda                         252:0    0   10G  0 disk 
├─vda1                      252:1    0  500M  0 part /boot
└─vda2                      252:2    0  9.5G  0 part 
  ├─vg_mungr-lv_root (dm-0) 253:0    0  8.6G  0 lvm  /
  └─vg_mungr-lv_swap (dm-1) 253:1    0  992M  0 lvm  [SWAP]

You can see what package a program is in with this command:

$ which lsblk
/bin/lsblk

$ rpm -qf /bin/lsblk
util-linux-ng-2.17.2-12.9.el6_4.3.x86_64

Other ways to find its package

$ yum whatprovides */lsblk
Loaded plugins: fastestmirror, priorities, refresh-packagekit
Loading mirror speeds from cached hostfile
 * base: centos.mirrors.tds.net
 * epel: fedora-epel.mirror.lstn.net
 * extras: centos.someimage.com

...

You can also use repoquery to look for packages that provide a particular executable, search by filename aka. -f:

$ repoquery -f */lsblk
util-linux-ng-0:2.17.2-12.9.el6_4.2.i686
util-linux-ng-0:2.17.2-12.9.el6_4.3.x86_64
util-linux-ng-0:2.17.2-12.9.el6_4.2.x86_64
util-linux-ng-0:2.17.2-12.9.el6_4.3.i686
util-linux-ng-0:2.17.2-12.9.el6.i686
util-linux-ng-0:2.17.2-12.9.el6.x86_64

Or you can do it using this:

$ repoquery --whatprovides */lsblk
util-linux-ng-0:2.17.2-12.9.el6_4.2.i686
util-linux-ng-0:2.17.2-12.9.el6_4.3.x86_64
util-linux-ng-0:2.17.2-12.9.el6_4.2.x86_64
util-linux-ng-0:2.17.2-12.9.el6.x86_64
util-linux-ng-0:2.17.2-12.9.el6.i686
util-linux-ng-0:2.17.2-12.9.el6_4.3.i686

Notice that the argument in most of the above examples is */lsblk. This allows repoquery to search for any matches whose path can vary, i.e. the */.

What does this program do?

If you ever want to know what package contains a given file on a Red Hat-based distro, use the whatprovides subcommand to yum. In this case you would do a yum whatprovides */lsblk

Thank you for all of your help. I think my problem is with the repos. None of those commands work.

<Hit return too soon> When I tried "yum install util-linux-ng", I still got "Nothing to Do".

@Tensigh - notice I said this is only available in CentOS 6+. It's not easily available for CentOS 5.

@Tensigh - it doesn't appear to be available in a CentOS 5 repository.
