Set some disk params to be safe

2013-09-05 3 min read Fedora Linux

It is always “Better safe than sorry” so, here are some things you
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 :

vim maps – simple commands to do stuff.

Some time back, I was working on some script for logging and I wanted to change the class to function like this:

$logger->Debug("Test string");
loggerFunc("Debug", "Test String");

As you can see, this change could be quite frustrating if you have quite a few references. And thus vim comes to rescue.

Simple map like ::

:map ,mm :s/(.*)$logger->(.*)((.*)).*/1loggerFunc("2",3);/

and then I can do “/$logger->” and then “n” to go to next match. Just do “,mm” and the line is re-factored.

power save mode for battery in Fedora 19.

2013-08-20 1 min read Fedora

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:

Delete all but some directories

I think, like me, you would have faced a lot of situations, where you wanted to delete all the files or directories in a location, leaving only the required files/directories. So, I have a directory containing lots of files/directories and I want to delete most of them except some 5/10 of them, how to I do it.

I finally wrote a small script to do that. First save list of files that you do not want to delete in file called “listnames” and then execute the below script. This will give you the rm commands that you need to execute. If you want you can execute the rm command from the script, but to be able to review, I just have the commands echoed.
