premier image file handling library. feh has many features,
from simple single file viewing, to multiple file modes using
a slideshow or multiple windows. feh supports the creation of
montages as index prints with many user-configurable options.

One of the reasons, I install feh as one of the first packages on any installation is the reason that it can open multiple images like in stack. To make things even more simpler I create a alias like this:

And sometimes there are software you find irksome and think things could have been better. In any case, I always like to try out a few alternative software choices before I settle with any particular application mainly for two reasons: One, you would never know how good or bad the one you are using is until you try some alternatives and two: a bit of choice and competition can only be for the good of us users!

Add current date and time in vim

Last few days I was quite busy. So this time very quick tip 🙂

Multiple search in vim

I was looking at a log file and needed to highlight multiple search items to make the logs more readable.

Calculations

<img src="http://blog.amit-agarwal.co.in/wp-content/uploads/2010/08/perl-one-liners.jpg" alt="Perl One Liners" align="bottom" />This is the third part of a seven-part article on famous Perl one-liners. In this part I will create various one-liners for calculations. See <a href="http://www.catonmat.net/blog/perl-one-liners-explained-part-one/">part one for introduction of the series.

Famous Perl one-liners is my attempt to create “perl1line.txt” that is similar to “<a href="http://www.catonmat.net/blog/awk-one-liners-explained-part-one/">awk1line.txt” and “<a href="http://www.catonmat.net/blog/sed-one-liners-explained-part-one/">sed1line.txt” that have been so popular among Awk and Sed programmers.

How a live distro can save you.

Some time back I wrote about <a href="http://blog.amit-agarwal.co.in/2009/03/07/" target="_blank">how to use a live distro without CD or VM. Today that experiment saved my day.

My RAM went bad couple of days without my knowledge and I kept using the system finally causing the &#8221;/usr&#8221; to be completed unusable.  And that is when I was able to still login to the system, as I still had that Nimble X installed on the HDD without actually installing it. Now I need to re-install the OS but at least for the time being I am able to use my system. 🙂
