-p, --persist lets plot windows survive after main gnuplot program exits.

-c scriptname ARG1 ARG2 ..., load script using gnuplot's "call" mechanism and pass it the remainder of the command line as arguments

-d, --default-settings do not read from gnuplotrc, ~/.gnuplot, and $XDG_CONFIG_HOME/gnuplot/gnuplotrc on entry.

-e "command list" executes the requested commands before loading the next input file.

-s, --slow wait for slow font initialization rather than continuing with an error.

-h, --help print summary of usage

-V, --version show current version

If file names are given on the command line, gnuplot loads and executes each file in the order specified, and exits after the last file is processed. If no files are given, gnuplot prompts for interactive commands.
