One of the most written and commented articles has to be Linux vs Windows (of course there are competitors like vim vs emacs) but none has been covered so much as Linux vs Windows. So, what am I going to write here which is not covered earlier in so many other posts. Well a little different perspective 🙂

nautilis fork ( File manager ) with tree view in sidebar.

2014-02-09 1 min read Fedora GNOME

Was searching for this for sometime now, finally found it.

sudo yum install nemo
sudo yum list nemo*

First just install nemo. Configure nemo not to interfere with default desktop and also make it default handler. So, here are the settings that would do it.

gconftool-2 --set  /desktop/gnome/applications/component_viewer/exec --type 'string' 'nemo "%s"'
gconftool-2 --set  /desktop/gnome/url-handlers/trash/command --type 'string' 'nemo "%s"'
gsettings set org.nemo.desktop show-desktop-icons false

Now, if you need more functionality in file manager then check the list of nemo packages from the output of second command of yum. It has plugins like file preview and so on. Install and enjoy.

sxiv – image viewer

2013-12-06 1 min read Fedora Photo

sxiv is a nice alternative to feh. It is very light weight and quite useful. Here is the description:

Description :
sxiv is an alternative to feh and qiv. Its only dependency besides xlib
is imlib2. The primary goal for writing sxiv is to create an image viewer,
which only has the most basic features required for fast image viewing (the
ones I want). It works nicely with tiling window managers and its code base
should be kept small and clean to make it easy for you to dig into it and
customize it for your needs.

zswap – compcache, compressed swap for better performance

2013-11-17 2 min read Linux

First, here is a link to article on compcache.

http://code.google.com/p/compcache/wiki/CompilingAndUsingNew

zswap is already in the kernel and you can see the documentation in the kernel documentation. Here is the name of the file if you need:

/usr/share/doc/kernel-doc-$(uname -r)/Documentation/vm/zswap.txt

Here is the overview, in case you do not want to install kernel-doc

Overview:

Zswap is a lightweight compressed cache for swap pages. It takes pages that are
in the process of being swapped out and attempts to compress them into a
dynamically allocated RAM-based memory pool.  zswap basically trades CPU cycles
for potentially reduced swap I/O.  This trade-off can also result in a
significant performance improvement if reads from the compressed cache are
faster than reads from a swap device.

Home grown mail scheduler with bash script and cron

2013-10-04 2 min read Bash Linux

If you are using Linux (Fedora/Ubuntu or anything else) then you do get a lot of tools and one of them is cron. Very very useful. Just write some script that can do the task for you, put it in cron and forget it. So, here is a home grown way to schedule mails.

First, copy this script below:

#!/bin/bash -
#===============================================================================
#
#          FILE: sched_mail.sh
#
#         USAGE: ./sched_mail.sh
#
#   DESCRIPTION:
#
#       OPTIONS: ---
#  REQUIREMENTS: ---
#          BUGS: ---
#         NOTES: ---
#        AUTHOR: Amit Agarwal (aka), 
#      REVISION:  ---
#===============================================================================

mailfile="~/mail"
if [[ $(wc -l $mailfile|awk '{print $1}' ) -ge 5 ]]
then
    to=$(grep ^To: $mailfile|sed 's/To: //')
    echo "Good to send mail... to = $to"
    sendmail -t <$mailfile
    echo "once mail is send, delete the contents of file"
    echo "sed -i '4,$ d' $mailfile"
fi

Now, create a file called mail in your home directory, with the following contents:
