Hello group,

In some scripts, I have seen the following construction for plotting which has a '< after plot command:

plot '< 

what is the use of it? what is it called to get more help on it?

Thank you
Sreejith

It basically executes what comes after the "<" as a shell command, and
pipes it´s output into the plot command.

Can be used to filter your data file, or directly hook gnuplot onto some
data source you´ve cabled to your computer.

See help on "special filenames", last section, or generally unix piping
and redirection.
