I think you accidentally posted the same code twice.

Anyway, we have no idea where aws_policy_effects, etc came from, so we cannot possibly say what order they're in.

Also, you can shrink that loop a lot:

Code:
STR=""
for X in "${aws_policy_effects[@]}"
do
        [[ "$X" == "Deny" ]] && STR="$STR DENY" || STR="$STR ALLOW"
done
aws_policy_effects=( $STR ) # Do not quote, splitting is intentional

...but it might have been easier to just pipe the data through tr 'a-z' 'A-Z' in the first place.

I'm sure that last block of code could be shrank too.

Probably all of it could use a good looking over and rewriting.

NAME
/usr/bin/BuildStrings -- Generate header (.h) or resource (.r) file from text files SYNOPSIS
/usr/bin/BuildStrings [-define variable] [-header] [-attributes attributeList] [-type filekind] -id ResID -in path -out path DESCRIPTION
The /usr/bin/BuildStrings command translates a text file into a resource or header file for use in localizing your Carbon application. The input file is a series of newline-separated pairs of newline-separated strings. Each pair of strings represents the "base" string and the localized equivalent. When generating a resource file, /usr/bin/BuildStrings generates a STR# resource containing only the localized equiva- lents (which must be enclosed in double quotes in the source file). When generating the header file, /usr/bin/BuildStrings generates a C header file with #define directives for each of the base strings (which must be valid C preprocessor symbols) equating each to the ordinal number of the string in the STR# resource. Your C/C++ source code can use these preprocessor macros, along with standard Resource Manager calls (like GetIndString) to load the appropriate localized string. The source file may include #ifdef/#endif (or #ifndef/#endif) directives to conditionally include different pairs of strings, e.g. for debug- ging builds or different versions. Note that these are the only preprocessor directives allowed in the source file. When generating a resource file, you can set the resource ID and attributes of the STR# resource by providing /usr/bin/BuildStrings with the appropriate command-line options. You can use /usr/bin/BuildStrings with several different sets of strings in the same application, for example, error strings and warning strings. The -type argument customizes some #defines in the generated header file so there are no conflicts. The /usr/bin/BuildStrings command accepts the following arguments: -header Generate a header file. If not provided, default is resource file format. Note that the file extension is not provided automati- cally; your output file name must have the appropriate .h or .r extension. -define variable Defines variable for use in #ifdef or #ifndef conditionals. No value may be assigned to variable. This argument may be repeated for any number of variables. -id ResID The resource ID for the STR# resource. There is no support for setting the resource name. -attributes attribute Resource attributes for the STR# resource definition (such as locked, preload, etc.) These are provided after the resource name in the resource definition. This argument may be repeated for any number of attributes. It is ignored if generating a header. -type filekind Customizes three preprocessor variables (MinValidFoo, MaxValidFoo, FooRsrcID) #defined in a generated header file. Note that if this argument is not provided, the default is the literal string "(null)", which will cause compile errors in the header file. -in path The input file, a set of newline-separated pairs of newline-separated strings. The first string of the pair is ignored for the resource file (but is provided in a comment) and is used as the preprocessor symbol in the header file. The second string of the pair is used as the resource string in the resource file and is ignored in the header file (but is provided in a comment), and must be enclosed in double-quotes in your source file. -out path The output file. Note that you should provide the appropriate file extension; it is not provided automatically according to the -header flag. SEE ALSO
