The first draft of the revised GNU General Public License (GPLv3) will be released during the “First International Conference on GPLv3″, at the Massachusetts Institute of Technology (MIT) on January 16 and 17 2006. The conference is open to the public and free of charge, though advance registration is required. The FSF has also launched the GPLv3 Development and Publicity Project which will bring together organizations, software developers, and software users from around the globe during 2006, in an effort to update the world’s most popular free software license.
Free Software advocates are hoping that effective provisions for software patents as well as GPL compatibility with other licenses will be prominent in the draft.

seq — Prints a sequence of Nos to Stdout.
Summary :
seq prints the numbers from Start to End in steps. By default, Start and Step are 1, and by default each number is separated by a new line. All numbers can be reals, not just integers.
Examples :
$ seq 6 — Print Nos from 1 to 6.
$ seq 2 6 — Print Nos from 2 to 6.
$ seq .1 .5 10 — Real numbers with factional step value 0.1.
$ seq 10 100 10000 — Print Nos from 10 to 10K with step value 100.
$ seq -w 10 100 10000 — All Nos are printed equal width.
$ seq -s’ ‘ 1 2 10 — Each number is separated by SPACE.
$ seq -f %1.f 1000000 1000001 — Print Nos with no exponent and no decimal point.
$ seq -f %e 1 5 — Print Nos with exponent and decimal point.
Note:
- Fractional increment may NOT end with END value.
- More formatting details are available in the info page.

I have installed a poll plugin for this blog and have started a new poll. The question is
“Which GNU/Linux distro you use“
I have added the following choices
- Red Hat Linux
- SuSe Linux
- Mandriva
- Debian GNU/Linux
- Ubuntu GNU/Linux
- I don’t use Linux
If your favourite distro is missing, please comment under this post. Also try to tell what are the best features that you find here. If anyone wants me to remove the poll (cause it is a lame question), feel free to comment.
Update: Added Gentoo as one of the choices.
I saw this huge list of Live CDs on Digg and found it to be interesting. I think it covers all the live CDs one can know.
Slax tops the list on the most popular(votes) and my favourite - Knoppix is at place 4 and Ubuntu is at 8.
tee - Read from stdin and write to stdout and files
Summary :
Tee will copy the stdin to file(s) and also to stdout output. Actually tee is doing the redirection. The following ASCII art will shows “How Tee works”.
StdIn >—+—> StdOut
|
|
|
V
File(s)
Examples :
$ tee — Read from stdin and write into stdout.
$ tee f1 f2 — Read from stdin and write into stdout, f1 & f2.
$ tee -i myfile — Same as above. But it will ignore the interrupt signals (Ex: ctrl+C).
$ tee -a myfile — Read from stdin and write into stdout & append to myfile.
$ who | tee myfile — Store the output of who to myfile and also write to stdout.
$ ls -1 | tee f1 f2 | wc -l — Store the ls output in f1, f2 & write the count of all files on stdout.
Read : man tee
Saw this nice site which displays a graph of the programming languages that were most sought after. Indeed is a site where one can search for any job listed.
The popularity of Python has been rising (though it fell in december) and so is ruby (steady rise). I still haven’t tried my hand at Ruby, though I got a book. I think I should see how it is. Also Lisp was in my agenda for a long time, but never had any time to do that.
So, what languages do you think are hot right now?
tree - List contents of Dirs in a TREE-like format.
Summary :
Tree is a recursive directory listing program that produces a listing of files in different formats according to the options.
Examples :
$ tree — Recursive listing of Dirs and files.
$ tree dir1 dir2 — list the files from Dir1 and Dir2.
$ tree -a — List all files including the hidden files.
$ tree -d — List only Dir entries.
$ tree -f — List file with full path prefix.
$ tree -i — List the file in the ls style.
$ tree -P ‘*txt’ — List the files with txt extension.
$ tree -I ‘*txt’ — List the file with-out txt extension.
$ tree -p — List files with permission info.
$ tree -s — List files with Size info.
$ tree -u — List files with User Name/ID.
$ tree -g — List files with Group Name/ID.
$ tree -D — List files with Last modified date.
$ tree -F — Add Symbols (as per ls -F) to the files.
$ tree -t — Sort the output by Last modified time.
$ tree -C — Turn On colorization.
$ tree -n — Turn Off colorization.
NOTE: By default, It will not be installed in RedHat Distro.

According to TheRegister, Microsoft has won its claim over the patent rights over its File Allocation Table(FAT) which was the default filesystem used on Windows. This could mean that Microsoft could go after FLOSS developers by forcing them to pay a royalty for using FAT. The US Patent and Trademark Office ruled that the file system is “novel and non-obvious” and, therefore, deserving of a patent. Do you really think so?
cd — Change the Current Directory
Summary :
If there is one command that I use frequently it is cd. cd is bash shell’s built-in command. It is used to change the present working Dir to specific Dir.
Examples :
$ cd — Change the current Dir to $HOME ($HOME is the default).
$ cd ~ — Same as above.
$ cd ~foo — Goto the Home Dir of foo
$ cd projects — Change the current Dir to projects
$ cd .. — Goto the parent Dir.
$ cd - — Goto the last visited Dir.
Tip:
CDPATH - Easy access to frequently used Dirs. For example, I use /usr/a/dir1, /usr/b/dir2/ and /usr/c/dir3 very frequently. So I added the above dirs CDPATH like this
CDPATH=/usr/a/dir1/:/usr/b/dir2/:/usr/c/dir3/
- Before changing to new path, cd will save the old path in the $OLDPWD evn variable.
- After changing to new path, cd will save the new path in the $PWD env variable.
