#!/usr/bin/perl
use strict;
use warnings;
use POSIX qw(strftime) ;

my $TimeStamp=strftime "%Y%m%d",localtime ;
system('wget -q --no-check-certificate -O /tmp/DataFile_$TimeStamp "https://foobar.com/html"') ;

I can't get the $TimeStamp to interpolate into the system command.

Any ideas on solving this?

Thanks in advance.
You need to allow the perl interpreter to interpolate perl variables.

Just try this.!

Code:
system("wget -q --no-check-certificate -O /tmp/DataFile_$TimeStamp 'https://foobar.com/html' ") ;

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
