Try the w and who commands.

If you should need more info about either of those commands, you can run man w or man who in a terminal.

Also, you can check out LinuxCommand.org for lots of good command line stuff:

Guys please help give example of cp command copying folder/folders and file/files from a source to a target.

Plus: Why cant I copy a folder going to "/usr/local". it says i am not an owner?

Hi usongiovanni,

Usage of cp command. Checkout

man cp

Examples:

cp path/to/source/filename path/to/destination

if want to copy entire directory or folder then use -r option.

cp -r path/to/source/directory path/to/destination


Make sure you got correct permission to copy the files.
