Not clear. What is the problem?
- Do you want to eliminate eval?
- Does the overall logics not deliver what you need? Please be aware that a chain -o (OR operators) stops after the first to evaluate to TRUE.
- How are the two code snippets in above related? What and/or where is filter 5?
- Why does filter 2 work in the first snippet but doesn't in the second.

I have a script that takes an option for server pools to run the script against. The option is given as a comma separated list (ie, -p 201,204,301).
I'm using eval and brace expansion to get those pool numbers into an array. It works fine unless only 1 pool number is given. Here's the code:

Hello,
is there a kind soul who can answer me, does the SH support double substitution known as indirect expansion similar to BASH? The syntax for bash is ${!var}.
For instance in bash I can write something like this:

and get the "value"... (1 Reply)

mimedefang.pl
MIMEDEFANG.PL(8) System Manager's Manual MIMEDEFANG.PL(8)
NAME
mimedefang.pl - Perl script to scan MIME messages.
SYNOPSIS
mimedefang.pl [-f filter] dir
DESCRIPTION
mimedefang.pl is a Perl script designed to work with mimedefang(8). It takes a single argument which is a directory which should contain
files laid out as described in mimedefang(8).
OPTIONS
-f filter
Specifies the name of the file containing the filter. If this option is omitted, the default filter /etc/mimedefang-filter is used.
OPERATION
mimedefang.pl evaluates the file /etc/mimedefang-filter as a Perl fragment. This file should define the filter procedure. For each part
of a MIME message, mimedefang.pl calls filter and disposes of the part as instructed by the filter. The various modes of disposition are
described in mimedefang-filter(5).
TESTING FILTERS
You are strongly recommended to test your filter before installing it in /etc/mimedefang-filter. To test the filter, save it in a file
(e.g. test-filter) and run this command:
mimedefang.pl -f test-filter -test
This tests the filter for syntactic correctness. If it passes, you can install it as a production filter. (Note that the test tests only
for correct Perl syntax; it doesn't make sure your filter does something sensible.)
MISCELLANEOUS OPTIONS
There are a few other ways to invoke mimedefang.pl:
mimedefang.pl -structure < mime_message
parses a message on stdin and prints lots of debugging information.
mimedefang.pl -prettyprint < mime_message
parses a message on stdin and prints it in a "nice" format (depending on your definition of "nice".)
mimedefang.pl -features
prints a list of detected optional Perl modules. The output looks something like this:
SpamAssassin: yes
mimedefang.pl -validate
calls the function filter_validate, if it is defined in your filter. filter_validate should return an integer; this becomes the exit code.
If filter_validate does not exist, an error message is printed and mimedefang.pl exits with an exit code of 1.
