Linux : tr (translate) command

I made a good use of the translate command recently to get month-name
in upper case. I needed this in a shell script. Here's the command

date +%b | tr [a-z] [A-Z]

Output: FEB

Consider freelancing !

Reasons why you should consider freelancing

* Freelancing provides you with chances to build your own business
contacts who will keep you busy.
* You are free to do many jobs at the same time.
* Nobody takes away your credit. You get rewarded for your work.
* You can work remotely from the comfort of your home. You save daily
commute which takes a lot of time.
* You can work when you are most productive. Flexibility of time is a
great advantage.
* You get good pay rate simply because there are no overheads. Money
is not lost to company administration or your manager :-)
* As I started writing this post, I thought someone must have done it
before so I googled and found that there's a list of 101 such reasons
on
http://www.hrworld.com/features/101-reasons-to-freelance-091007/
I never considered all those reasons before starting freelancing myself.
* Finally, because it's become hard to get a job when the world is hit
by recession.
