10 Linux How -To's

i am a newbie to linux. I have osme questions that i am sure i will find answers from you people. So without further delay .....
Q.1 If you need to execute all shells in a particular directory, say you have 20 shell scripts to execute one after the other. How you will do it?

Q.2 How you can make a file or directory "immutable" that is file cannot be modified or deleted; even by ROOT?

Q.3 How would you take backup of only the last accessed files from a directory?

Q.4 How can you quickly find (locate) the path of any linux command or system file/dir? Such as I need to know that from where the command "cp" runs? or where the system directory "rc1.d" located?

Q.5 Linux command "cat" can be used to display contents of a file from top-to-bottom, what if you wish to display contents from bottom-to-top?

Q.6 How can you display file last accessed/modified/changed/size/file-type/Inode No/permissions/Creator/Group Owner using just one command?

Q.7 If you send an important file to someone remotely (via email), is there any simple way that you can ensure that the file received by user is the same that
you send him? HINT: Message Digest

Q.8 How can you check the login status based on users created in /etc/passwd? that which users logged-in when? and which users never logged-in?

Q.9 How can you apply security to your linux box, to block ICMP? no one should than be able to ping the machine remotely on network?

Q.10 Using which command; you can display the system current status? (processor, memory, users, swap and other system status).
Many many thanx in advance for answering these questions. I am waiting......

These look like homework questions. There is a policy on this board against doing peoples homework.

I would recommend reading the core-utils manual. The most common commands are a part of core-utils, and you will learn a lot from linux by reading this one.

If you install the core-utils source, there is a target for "make ps" and maybe even "make pdf". This will get you a print worthy version of the manual. Elsewise, you can use the "info core-utils" command instead.
