When gnuplot is run, it first looks for a system-wide initialization file gnuplotrc. The location of this file is determined when the program is built and is reported by show loadpath. The program then looks in the user's HOME directory for a file called .gnuplot on Unix-like systems or GNUPLOT.INI on other systems. (OS/2 will look for it in the directory named in the environment variable GNUPLOT; Windows will use APPDATA). Note: The program can be configured to look first in the current directory, but this is not recommended because it is bad security practice.
