Use the -a flag to display all files, including hidden files. If you just want to display regular files, use a -1 (yes, that is the number one). Got this by RTFM and adding some sed magic.

[bbbco@bbbco-dt ~]$ ls -a | sed "s#^#${PWD}/#"

This is one way to find out.

A short way to give us relevant report in a moment done about quantities on disk usage, memory and swap in our Linux Systems.

Just type 2 characters and enter, you will be back.

knows more extension and checks MIME types also, if file extension not matched

I think it would be wise if anyone voting down left a comment indicating the reason for that action. Don't keep it to yourself. Thanks.

Normally, if you just want to see directories you'd use brianmuckian's command 'ls -d *\', but I ran into problems trying to use that command in my script because there are often multiple directories per line. If you need to script something with directories and want to guarantee that there is only one entry per line, this is the fastest way i know

To save all rules so that they are not lost in case of a server reboot:

/etc/init.d/iptables save

This is really not cli but I think it's neat.

Autojump is cd command that learns. More info: http://wiki.github.com/joelthelion/autojump

Somehow, i prefer forcing to rm interactively to accidently rm'ing everything...

This opens up nautilus in the current directory, which is useful for some quick file management that isn't efficiently done from a terminal.

unalias a previously aliased command

This should work on any RPM-based distribution. It's more reliable than trying to parse the content of the files.

Simply displays your current working directory. Helps when you are buried deep in /etc or some other obscure place.
