Search and Replace a string in any file

In UNIX environment, the following combination of perl and find will serch for a particular file and replace the occurence of a particular string with another string in that file. This will also work for multiple files and directories. The find command finds the file and the perl script replaces old string with the new one. perl -pi -e 's/old string/new string' `find . -name "file name"`

Voice Chat with Linux

The Scoop

Tired of all the windows users having all the fun? Well, Speak Freely is your answer.

Let's Get Going

Speak Freely is very simple to install if you are using Debian Linux. apt-get install speak-freely If you are using one of the other distributions then head over to their site and download the rpm and install it. Be sure to grab the latest version since it comes with the TK front end.

Getting through the firewall

If you happen to have a Linux firewall, then you will need to issue the following command. The following command only works if you are using ipchains:
ipmasqadm autofw -A -r udp 2074 2075 -c udp 2075
The Benefits

During using SpeakFreely I have found it to be clearer than any other program I have used (yes any). Another great benefit of it is the encryption over the wire it offers, as well as the different levels of compression it supports. If you have any troubles then post a comment, I am sure someone or myself will get back to you with an answer.

Speak Freely

For awhile now, I have been wanting to find a really nice chat program that does voice. A lot of people now have static high speed connections to the Internet so it wouldn't be that hard really for us to save a little on our phone bills. The problem is that there are some nice chat programs but mostly for Windows. I bumped into this program today and found that it runs on both Windows and Linux platforms, Speak Freely. There is a TCL front end for the program so be sure to download that as well. One of the cool features of Speak Freely is the capability to encrypt your messages using PGP or other known methods. Now that is what I call an open source twist to chatting.
