The problem is not the iteration in itself. The problem is that expanding an array like "${array[*]}" might lead to a line that is longer than "MAXLINE" and/or consisting of more elements than "MAXARGS" allows for. You can experience the same phenomenon when using

Code:
for file in * ; do ...

Thi swill work well for any "normal" directory, but might break with a "line too long" if there are awful lots of entries in there. Instead of the for-loop the while-loop will not break:

Code:
ls | while read file ; do ...


I hope this helps.

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 ATTRIBUTES
