[gentoo-user] Can a script tell if it's running under X?

[Kevin O'Gorman]

Is there a way for a script (bash, for instance) to know
if it's running under X, such as in an xterm or konsole?

I want to have scripts that run graphical tools if the
infrastructure is present, and text tools otherwise.
For me this is particularly useful for tools I don't use
all that often, and can forget that a graphical version
exists.
