Hey Corona, thanks for the reply...

Yeah funny you say that, I actually just noticed that a little while before I read your post... Thanks!


UPDATE:
So I'm guessing I ran into a little Perl version problem on some of our older servers...
When I ran the REGEX on the machine I'm testing this on, it worked perfectly... But when I transferred it over
to another server running Perl v5.8.2 and another with v5.8.8 it didn't do anything to the "strings" at all.

So what I did was, I tried to simplify the REGEX, because I'm guessing it matched ANY/ALL V100 Character
Sequences, but I ONLY needed to look out for the ones for BOLD "\033[1m", and the one for OFF "\033[0m"
and possibly the one for UNDERLINE "\033[4m"...

Strangely though, those escape sequences above are how you would enter them into a bash script, like this:
i.e. --> echo -e "\033[1m THIS PRINTS BOLD \033[0m"

Then if I redirect the echo statement into a txt file, they show like this instead of what's above...
i.e. --> "^[[1m THIS PRINTS BOLD ^[[0m"


So here's my new REGEX (also I changed the while loop to just a 'cat' command):
Code:
outputFile="/usr/local/test/Output.txt"

### Split the output of the 'cat' command on newlines, and insert it into the array FILE_Lines...
IFS='
'
FILE_Lines=($(cat $outputFile | perl -pe 's/\^\[\[(1|0|4)m//g'))

for (( x=0; x<=${#NRPE_Lines[@]}; x++ ))
 do
    echo ${NRPE_Lines[$x]}
done

So far this seems to remove ALL the escape sequences from the file, so I guess
I'll use this one until or if/when something else goes wrong lol...



Thanks again you guys for your suggestions... Much appreciated!!


Thanks Again,
Matt

With that logic this echoes "echo". Question about echo!

echo `echo ` doesn't echoes anything. And it's logic. But echo `echo `echo ` ` does echoes "echo". What's the logic of it? the `echo `echo ` inside of the whole (first) echo, echoes nothing, so the first echo have to echo nothing but echoes "echo" (too much echoing :P):o (2 Replies)

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME

       Test::Script - Basic cross-platform tests for scripts

DESCRIPTION

       The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or
       bin as is also commonly used) paths of your Perl distribution.

       Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible.

       That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is
       considered unacceptable.

       In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking
       that your module won't on some platform because of the dependency.

       Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform
       safety.

FUNCTIONS

   script_compiles
	   script_compiles( 'script/foo.pl', 'Main script compiles' );

       The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl).
       This will also be shown in the diagnostic output on failure.

   script_runs
	   script_runs( 'script/foo.pl', 'Main script runs' );

       The "script_runs" test executes the script with "perl script.pl" and checks that it returns success.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also
       be shown in the diagnostic output on failure.
