I wrote a script that takes a large data set (~30k points) and pulls out meaningful info to graph with GNUPlot. It works really well when I want to graph one file at a time. Below is the striped down version of the code.

I need to do this for a bunch of files. I would like to designate each file path at the top and then have the code run through for each file. I tried using a matrix but it didn't seem to work with the 'foreach' command.

So, What is the best way to run the same script on multiple files? 

# Columns to be written to the output file and Plotted.
$c1 = 4;    # X-Axis
$c2 = 16;    # Y-Axis
$c3 = 11;    # Z-Axis

# Single file to be Opened
$file1 = '../filename.asc';
open(Read, $file1);
@Read = <Read>;            # Read file into an array

# Visit each text line in turn and write data in specific column to ar
+ray
foreach $part (@Read) {    
    $part =~ s/ /:/g;
    @Row = split(/:+/, $part);
    push(@Write, "$Row[$c1]\t");
    push(@Write, "$Row[$c2]\t");
    push(@Write, "$Row[$c3]\n");
}

# Creates the plotted data file
writeFile_ref ("PlottedData.txt", \@Write);
close(Read);


# Opens GNUPlot and Creates Plots
open(G, "|/usr/local/bin/gnuplot") or die "/usr/local/bin/gnuplot"; 
print G <<ENDOFHERE
set term x11
splot 'PlottedData.txt'
ENDOFHERE
