Backup & Bulk Copy
During academics, we have heard so many times about backups.

Monitor Your Website
While the whole issue was talking about web security, I thought of writing something on the same lines In this issue of command line gyan, we’ll see how we can monitor our websites automatically so as to get notified if anyone defaces it. Nothing very great in this and there are a lot of services giving this feature in cheap, but the fun is to write your own dirty little script to help you.


Who is leaving my home?
You can say that my antivirus is up-to-date and it will take care of the same, but having said that are we sure all the malware are caught by ‘my’ antivirus?

Tethering your android
Frankly this issue of “Command Line Gyan” does not have as much flesh as previous issues. But we thought of dedicating this issue to Android so here we are with a small article on how to tether your android.

Other devices may connect to the gateway via Bluetooth, Wi-Fi or by Universal Serial Bus (USB) cabling.” The connectivity can be normal GPRS/EDGE or most awaited 3G. At the same time other device can be other wi-fi enabled phone/pda, laptop or even desktop.

We also know that there are a bunch of freeware & commercial tool to do so, but the idea is to achieve this from built-in commands/utils in a system. Remember you might get stuck on a machine where you don’t have your favorite tool and might not be connected to internet to download the same

A splash on firewalls
I’m sure you all know that almost all operating system have a kind of inbuilt firewall. Windows has “Windows firewall” whereas the Linux has “iptables”.


Counting & Matching Text in Files
