How can I see a progress bar when copying/moving files?
You can't with cp(1), but you can either:
build one yourself with tools such as [http://www.ivarch.com/programs/pv.shtml pv] or [http://clpbar.sourceforge.net/ clpbar];
use some other tool, e.g. [http://members.iinet.net.au/~lynx/vcp/ vcp].
You may want to use pv(1) since it's packaged for many systems. In that case, it's convenient if you create a function or script to wrap it.
For example:
pv "$1" > "$2/${1##*/}"This lacks error checking and support for moving files.
