In my previous post on check filesystem regurlarly, I mentioned tune2fs. That tool give quite a lot of information. But just in case, you did not find what you are looking for in the output, then you can get much more information on these partitions with the dumpe2fs command.
Continue readingIf you are looking for the source of a mount and the various options used in the mount, then the quickest way to get that is ::
findmnt
By default, with no parameters, it lists all the mounts in a tree like view and all the options used to mount the path. It also lists the source of the mount.
By default again, it uses some capabilities of the terminal to show the tree which you can disable with the option “-a”.

should do..
First check fstab, if you have partitions other than root then use UUID instead of device:
UUID=a8f13a0d-3f1f-42e4-b076-f44b4163306c /mnt/Backup ext4 defaults,relatime 1 2
Then entries for all your mounts should be like above.
Points to note here :
Disk is mounted using the UUID and not with /dev/sdXX. This ensures
that even if your disk ids change, you will be able to mount them. To
get the partition UUID, you can execute :
pkgwat is a nice utility to search the fedora packages websearch.
Description : Pronounced "package WAT", pkgwat is a fast CLI tool for querying : the fedora packages webapp. : https://apps.fedoraproject.org/packages/ : : You can make its search even better by helping us tag packages. : https://apps.fedoraproject.org/tagger
And to search for a package, you can use ::
pkgwat search pkgwat -h # get help on package.

I was getting really bad battery life on my Fedora 19 system, and did not find much on how to tune it. Finally I found something that just does not need much configuration but works pretty well. So, here is what you need to do:
sudo yum install tuned tuned-adm
The second package, tuned-adm installs additional themes for power saving. It is optional and not mandatory. Once you have installed these, you can do the following:
Continue readingIn Fedora, ramdisks are not created by default as is the case with RHEL. So, if you need to get Ramdisks on Fedora, then you can do this:
sudo yum install MAKEDEV
This will create some default Ramdisk’s in the “/dev” directory. Now, if you need to change anything then feel free to go to “/etc/makedev.d” and feel free to change these files.

For a long time I have not posted any script. So, its not that I have not written anything new, but just that did not put them here in lack of time. So, here is one interesting one. The original idea came from one posted in one of the interesting blog here. But the problem with this one was that for every time, it ran in the cron, it would make multiple entries in the “last” output (about 10 or more with my modifications for differentiating between solaris and Linux). This is something which is not quite desirable. Hence I came up with this script which is based on html template and hence the output is also easier to manipulate. BTW, just the below script will not help, you would need to download the template files as well. In the list.txt file, you will have to put the usename, password and the server IP to monitor. The server could be any Linux or Solaris host.
