The name of the input file must be enclosed in quotes.
The special filename "-" may be used to load commands from standard input. This allows a gnuplot command file to accept some commands from standard input. Please see help for batch/interactive for more details.
On some systems which support a popen function (Unix), the load file can be read from a pipe by starting the file name with a '<'.
load 'work.gnu' load "func.dat" load "< loadfile_generator.sh"
The load command is performed implicitly on any file names given as arguments to gnuplot. These are loaded in the order specified, and then gnuplot exits.
