comment Delete every users from a group
Either make sure you have the root password set, or better leave at least one user in the sudo group that can keep this privilege. Also make sure you have an extra open root shell when experimenting with this, so you can always revert your changes.

comment Galculator does not compile
You probably need one or more .....-dev packages, but since you didn't include much of the error messages, I cannot tell which. Just search the internet for missing funtion names and related ...-dev packages that will provide you with the related header files.

comment print a file in hex using awk
Not sure what you are trying to accomplish, but it'll probably work if you change the file contents to contain a single character per line. If that gives the output you are looking for, then we can help you change the awk script. Also what's wrong with hexdump -C?

comment Machine data not displaying every 15 Seconds
You can change grep -v grep | grep "vmstat 15" to grep "[v]mstat 15", it is slightly safer in matching.

And of course you will turn off password authentication (in favour of key authentication) if you directly connect to Internet.

comment Why can an unpriviliged user execute the `sync` command?
What is that useful for? BTW there is no password on the sync account on the box I am currently working on, so that won't work.
