[Nagiosplug-help] Strange problem with Bash, AWK and check_http

[Edward Blum]

Hi There,

I am having very strange problems creating a nagios plugin in Bash using
check_http to check contents of a Amazon S3 Bucket.

I am grabbing the URL of the file to grab from a txt file (changes often)
inside the bucket and using awk and grep extracting the Filename.

I have using the following syntax:

check_http -H myhost.com -N -v -u /testing.exe

Now this works fine when I run from the command line it also works fine
when running from the bash script. The problem lies when I try the use the
variable extracted using awk.

Here are the results of running my bash script :

is 135 charactersktdfde.co.uk:80/SetupddfImporter1020.exe<http://charactersktdfde.co.uk/SetupddfImporter1020.exe>

In the bash script I am using the syntax:

test=$(cat /tmp/updates.txt | grep ServerFileName | awk
'BEGIN{FS="="}{print $2}' | grep HHR)
command="$check_http -v -N -H update.efefktdfde.co.uk -u"/"$test"

If I just do test=SetupddfImporter1020.exe then call command it works fine,
so I would think its my variable however if I run a If statement to check
if the one generating by the awk command is the same
as  test=SetupddfImporter1020.exe it says they are equal/

This is driving me round the bend, any help would be much appreciated!!
