what is syntax of linux commands
 

I have just started learning linux 9 i am finding some difficulty in understanding syntax of linux commands. Is it mentioned in books or else anywhere in articles etc.

The syntax varies from one command to another. For specific commands, the best place to look with regards all the options is in the man pages. So, to find out more about 'ls', for example, you'd type into a terminal: Typing 'q' (without the quotes) will allow you to exit from the man page.

There are also a large number of guides on all aspects of Linux. A pretty comprehensive one it RUTE: http://rute.2038bug.com/rute.html.gz or http://www.icon.co.za/~psheer/rute.pdf.bz2

As an aside, if Linux 9 means RedHat Linux 9, I strongly urge you to install a more up to date distribution as all support for RedHat Linux 9 ceased in April 2004 - including security updates. For the current RedHat community Linux distribution, see www.redhat.com/fedora

Yiou can find some tutorials on the internet as long as you know how to use google. More detailed coverage can be found in the books listed by pixellany. I would also recommend "A Practical Guide to Linux Commands, Editors and Shell Programming" by Mark Sobell.
