How can I set the contents of my terminal's title bar?

If you have a terminal that understands xterm-compatible escape sequences, and you just want to set the title one time, you can use a function like this:

settitle() { printf '\e]2;%s\a' "$*"; }

If you want to set the title bar to the currently-running command line every time you type a command, then this solution approximates it:

trap 'printf "\e]2;%s\a" "$(HISTTIMEFORMAT='' history 1)" > /dev/tty' DEBUG

However, it leaves the command history number in place, and it doesn't trigger on explicit subshells like (cd foo && make).

Or to use just the name and arguments of the current simple command:

trap 'printf "\e]2;%s\a" "$BASH_COMMAND" > /dev/tty' DEBUG

== 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:

-This lacks error checking and support for moving files.
