Hi, Bart. thanks for the help. I can work with the execution time of ls
included, no problem.
that's because I can compare the execution time of ls in the same dir, with
the plugin, and without the plugin. The difference between the two tests
will give me the performance hit of the plugin.
But I did not really understand where I have to declare SECONDS.See if I
understand correctly. I'll open my zshrc and type this:
is that right?
Also, is 4.800e+2 = 480 milliseconds?
