Full Discussion: Call a Perl script within a bash script and store the ouput in a .txt file

Network Call a Perl script within a bash script and store the ouput in a .txt file
I'm attempting to write a bash script that will create a network between virtual machines. It accepts three arguments: an RSpec that describes the network topology, and two list of machines (servers and clients).
I have a (working) Perl script that I want to call. This Perl script takes an RSpec and finds the machine names and/or IP addresses, and prints them to the STDOUT.
What I want to happen is for the bash script to call the perl script (which is in a subdirectory), and pipe the output to a .txt file. Right now, I keep getting an error saying the perl script doesn't exist, though I am giving it the full pathname.
This is the bash script:
Code:
#!/bin/bash
case $# in
3) ;;
*) printf "Need three arguments!\n"
   exit 1 ;;
esac

perl "$HOME/Documents/begPerl/etIDs.plx" "$1" > "$HOME/Documents/ AllMachines.txt" || exit 1

The error I'm getting is:
Code:
Can't open perl script "/home/*****/Documents/begPerl/getIDs.plx": No such file or directory

If it helps any, I'm using ubuntu on a VirtualBox VM (physical machine is a MacBook Pro). (The starred out text was a folder containing my name...)
Any and all help (and explanations, too) would be greatly appreciated. I'm relatively new to both perl and bash (only been using these languages for a few months).
I am aware that there are other threads dealing with similar topics, but I could not find one that suited this problem specifically.

bashbug

BASHBUG(1)						      General Commands Manual							BASHBUG(1)

NAME

       bashbug - report a bug in bash

SYNOPSIS

       bashbug [--version] [--help] [email-address]

DESCRIPTION

       bashbug	is  a shell script to help the user compose and mail bug reports concerning bash in a standard format.	bashbug invokes the editor
       specified by the environment variable EDITOR on a temporary copy of the bug report format outline. The user must fill  in  the  appropriate
       fields  and  exit  the  editor.	 bashbug  then	mails the completed report to bug-bash@gnu.org, or email-address.  If the report cannot be
       mailed, it is saved in the file dead.bashbug in the invoking user's home directory.

       The bug report format outline consists of several sections.  The first section provides information about the  machine,	operating  system,
       the  bash  version, and the compilation environment.  The second section should be filled in with a description of the bug.  The third sec-
       tion should be a description of how to reproduce the bug.  The optional fourth section is for a proposed fix.  Fixes are encouraged.

ENVIRONMENT

       bashbug will utilize the following environment variables if they exist:

       EDITOR Specifies the preferred editor. If EDITOR is not set, bashbug defaults to emacs.

       HOME   Directory in which the failed bug report is saved if the mail fails.

       TMPDIR Directory in which to create temporary files and directories.
