Hello people. I am completely new to Unix. I wanted to ask you if there is any website that has a list of only QUESTIONS that I can practice some basic commands with..only list of questions testing usage of commands in different ways?? Actually I have an open-book beginners exam coming soon and i want to practice as many twisted questions as possible.

Secondly,is there any way of retrieving file permissions apart from in a LAYMAN readable form. "ls -l" retrieves file permissions in the form od -rw-rw---x 12 owner.name group .......

say i want the information in a table like style.

Owener read write ----
group read write ---
other ---- ---- exec

I can do it using echo and create a table using tabs and all...
and so on....

Thirdly, I am using SSH prtocol to access a unix server to practice all commands. Is it possible that some commands dont run in the same way as they would on an actual unix machine.

hi all, is there any way of referring to individual members of a varible.

like var=kati
so $var(1)='k' or somthing like that.

i am trying to display the file format in a tabular form..
so i thot i can use a loop for checking the exact value of each character and then displying the file permissions in a table..
