Question

I am trying to print the array but the out put contain only the last line of the array. the partial code is as follow.

open OUT, "> /myFile.txt"
    or die "Couldn't open output file: $!";

foreach (@result) {

    print OUT;
}

the out put is

List Z

which is the last line, but when I do print "@result" the out put is

List A

List B

List C  so on...

I am little bit confuse why the results are different on the same array.

Answer 1

the problem is here

open OUT, "> /myFile.txt"

this should be

open OUT, ">>", "/myfile.txt"

What you wrote overwrites the entire file for each iteration of the foreach(@result) loop.
What you are intending to do is append to it (“>>”).
“>>” appends, “>” overwrites.

Also take note of how i broke “>> /myfile.txt” into “>>”, “/myfile.txt”.
This is both more secure, and more robust for less specific applications of open.
