How to install GScrot – Screenshot Tool


Update [  Feb 16 2009 ] – GScrot has been renamed to Shutter.

GScrot is a popular screen-shot tool for Linux. GScrot is currently at version 0.64. It runs best on GNOME and has a good feature list.

  • Capture a website, whole desktop, individual window or a custom selection.
  • Support for delayed screen-shots.
  • Plug-ins for multiple effects.
  • Support for FTP uploads and image hosting services., and
  • Save your screen-shots in the same folder everytime and automatically name them.
  • Full intergration with GNOME desktop panel.
  • Automatically generate thumbnails
  • Built in image editing tool.

I’ll walk you through the process of installing GScrot on Ubuntu 8.10. I’m more of a command line guy so if you need a GUI version look here.

Create a new apt-repository source file. I’ll call it  gscrot.list and place it in the “/etc/apt/source.list.d/” directory.

Add the following lines to the /etc/apt/source.list.d/gscrot.list file you just created.

deb intrepid main
deb-src intrepid main

Next, run “apt-get update” to update the apt-repository database.

root@python:/etc/apt/sources.list.d# apt-get update

Run “apt-get install gscrot” to download and install GScrot.

root@python:/etc/apt/sources.list.d# apt-get install gscrot

To start GScrot, go to Applications –> Accessories –> GScrot

How to find the number of physical CPUs in Linux

With multicore CPUs it’s easy for newbies to get confused when faced with questions like;

1. How many physical CPUs does the server have?

2. How many cores on each CPU? Duo/Quad

In Linux it’s actually quite easy to get this info.

You could go through the /var/log/dmesg file or the /proc/cpuinfo file. For this tutorial we’ll look at the /proc/cpuinfo file.

Physical CPU count?

Run “cat /proc/cpuinfo | grep “physical id” | sort | uniq | wc -l”.

[root@bender ~]# cat /proc/cpuinfo | grep “physical id” | sort | uniq | wc -l

How many cores?

Runcat /proc/cpuinfo | grep “cpu cores” | uniq”.

[root@kmigb000 ~]# cat /proc/cpuinfo | grep “cpu cores” | uniq
cpu cores       : 2

2 mean that each physical CPU has 2 cores on it. If cpu cores was 1 then the CPU’s single core.

How many virtual processors?

Run “cat /proc/cpuinfo | grep “^processor””

[root@bender ~]# cat /proc/cpuinfo | grep “^processor”
processor       : 0
processor       : 1
processor       : 2
processor       : 3

That’s about right, 2 physical CPUs x 2 cores each = 4 virtual processeors.

However, it’s a bit different for HT (Hyper-Threading). If you get cpu core = 1 but the virtual processors = 2 then the CPU’s running HT. HT will only work with the SMP kernel.
