Julia, ploting histogram or whatever from a serie of files in a loop (list)

Time ago, I did move some files from a directory and copied to a new one, while copying I did rename each one. For doing so , I used bash. Something like this

for i in 8 12 16 20 ; do;
   for j in 0.00 0.01 ; do ;    
    cp  tera.dat new/tera$i$j.dat 
...

Into each tera$i$j.dat, there is numeric data in 2 columns. I would like to plot the data as a histogram, and save each image (if possible in a loop) for each file tera$i$j.dat . But unfortunately, I do not have much idea how to do this. I managed to load the data in several tables using de = readtable.(filter(r"tera", readdir()),separator =' ', header= false,;. But I can not create a plot for each data :( So far I managed to read the file, and create a histogram plot for 1 file per time, how do I do it in a loop ? This is the code I am using.

using Plots StatPlots,  Distributions, DataFrames, PlotlyJS, LaTeXStrings;
theme(:sand);
chp = pwd(); 
pe = readtable("tera120.00.dat",separator =' ', header= false)
gr()
histogram(pe[2], nbins=1000)
...

Thanks in advance :)

Untested, but it should be something like this:

using StatPlots, DataFrames
theme(:sand)
gr()
for i in [8, 12, 16, 20], j in [0, 0.01]
    fn = @sprintf "tera%02d.%02d" i j
    pe = readtable(fn*".dat", separator =' ', header = false)
    p = histogram(pe[2], bins = 1000);
    savefig(p, fn*".png")
end

Note that when you plot with StatPlots, you don't need using Plots or using PlotlyJS, I also don't see why you need Distributions or LaTeXStrings.
