Look back file days in PERL
I have 3 variables , $file =abc_2011_11_01.txt (current day file), $back = Yes and $forward = No
I need to search for 3 days back files / 3 days forward files if my current file is not present
logic is,
I need to download the current day file.
If it is missing, i need to look out for currentday -1 file. (abc_2011_10_31.txt )
If that is missint, i need to check for currentday -2 file (abc_2011_10_31.txt )
If $forward is Yes , then I need to look out for currentday +1 file (abc_2011_11_02.txt )
If that is missing, I need to look out for currentday +2 file (abc_2011_11_03.txt )
IMP : The number of days file to check keeps changing. Eg: it may be 3, 4 or 9 etc...
Also, i need to check every file thrice with a sleep time of 100 seconds
How can i achieve this forward/backward check of files in perl?
Thanks in advance

check-permissions
check-permissions(1M) System Administration Commands check-permissions(1M)
NAME
check-permissions - check permissions on mail rerouting files
SYNOPSIS
/usr/sbin/check-permissions [login]
DESCRIPTION
The check-permissions script is intended as a migration aid for sendmail(1M). It checks the /etc/mail/sendmail.cf file for all configured
alias files, and checks the alias files for :include: files. It also checks for certain .forward files. For each file that check-permis-
sions checks, it verifies that none of the parent directories are group- or world-writable. If any directories are overly permissive, it is
reported. Otherwise it reports that no unsafe directories were found.
As to which .forward files are checked, it depends on the arguments included on the command line. If no argument is given, the current
user's home directory is checked for the presence of a .forward file. If any arguments are given, they are assumed to be valid logins, and
the home directory of each one is checked.
If the special argument ALL is given, the passwd entry in the /etc/nsswitch.conf file is checked, and all password entries that can be
obtained through the switch file are checked. In large domains, this can be time-consuming.
OPERANDS
The following operands are supported:
login Where login is a valid user name, checks the home directory for login.
ALL Checks the home directory of all users.
FILES
/etc/mail/sendmail.cf Defines environment for sendmail
/etc/mail/aliases Ascii mail aliases file
