Print @array content to a file

Shell Programming and Scripting
1

Hi, as the title, I have an array @f_lines with gene information in it. How can I put the content of @f_lines into a file so that I can read it?

I tried this:

open(OUTPUT, "file"); # put gene information in this file;
@f_lines = ("gene1", "gene2", "gene3"...); # gene information;
print OUTPUT @f_lines;
close(OUTPUT);

I didn't get any warnings, neither did i see gene information in "file".

Does anyone know the problem? Thanks very much for help~

By the way above is part of the script I ran in a shell.

open(OUTPUT, ">file");

Yes I did put ">" in. Sorry I forgot to post that.

Hi.

This code:

#!/usr/bin/env perl

# @(#) p1	Demonstrate write to file.

use warnings;
use strict;

my (@f_lines);

open( OUTPUT, ">file" );    # put gene information in this file;
@f_lines = ( "gene1", "gene2", "gene3" );    # gene information;
print OUTPUT @f_lines;
close(OUTPUT);

produces:

leap 1224 $ ./p1
leap 1224 $ cat file
gene1gene2gene3leap 1224 $

For this context:

OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
perl 5.10.0

You may have missed the line if you didn't include a newline.

Best wishes ... cheers, drl
