I wanted to create a perl script to check if a directory exists, and if it doesnt i want to crate one.It doesnt work in /etc,whereas the same code runs in other directories.any help would be appreciated.

my $username = getpwuid( $< );
print "$username\n"; 
if($username ne "root"){
     print "please run this script as root.\nsudo perl automation.pl\n
+";     
exit; }else{ 
    opendir(ETC,"/etc");          
unless(-d "Automation"){         
     mkdir("Automation");         opendir(AUTOMATION,"Automation");   
+          open(CRONTABFILE,">crontab");             flock(CRONTABFILE
+,2);             
$cronjob = "0 12 * * * /usr/bin/perl /etc/Automation/aptscript.pl";   
+      
print CRONTABFILE "$cronjob";             close(CRONTABFILE);         
+             open(APTSCRIPT,">aptscript.pl");             flock(APTSC
+RIPT,2);             
print APTSCRIPT <<'EOF';                 #!/usr/bin/perl              
+   
print "replace this script with the logic of the download of the deb f
+ile"; 
EOF             
close(APTSCRIPT);             
closedir(AUTOMATION);             
closedir(ETC);                  
} }
