Hi Aasif Shaikh,

Excellent Idea.

IMHO, please write a small simple howto on what each of those commands does, and also most common options they are used with. This would be an invaluable quick lookup resource for any Systems Administrator.

We can put this up on the GNU/Linux Users Group Mumbai wiki so that the entire community can contribute to it.

How does this sound ?

Hi Vivek,

It sounds great. I'll start composing this how-to. Meanwhile, can you please tell me whom should I submit this how-to?

Thanks for your valuable opinion.

I have edited the URL http://db.glug-bom.org/wiki/index.php/Howtos and added the topic 'System/Network Administration' in the contents section.

Start adding to those pages for a start, and then we can all collaboratively edit and maybe even later move those howtos under other relevant sections if needed in the future as the contents grow.

At least you now have a stadium and also a pitch to open your innings :-)

Hi Vivek,

Thanks for the stadium and pitch, innings will start this weekend :)

Arun Khan,

Thanks for appending the list with pstree.

Deepan Chakravarthy,

Monit is not a bad idea but I guess it's an application server with thread-pools and event driven i/o architecture. As of now, we would like to start composing the wiki with the basic command line utilities with there common usage.

I feel like "MONIT" should be covered completely in a different section. Not sure, if you agree with me but you can correct me if I am wrong.

Kind regards, Aasif Shaikh

29. pstree

pstree lists the processes in a tree like manner. I find it very helpful when multiple instances of a program are running and I need to take action on a specific instance only.
