sed -r not properly working in chef

I am writing a recipe in chef in which I have used script resource with bash interpreter to execute sed command :

    script 'find the lastest version of the major release available' do
        interpreter "bash"
        code <<-EOH
        SUBMGR_REPO=$(ls -1d /net/gutstools.am.lilly.com/guts_dev/distr/redhat/* | egrep `echo as6-u7_64 | sed -r 's/([aw]s[[:digit:]]+).*$/\1-u[[:digit:]]+(_64)?$/'` 2>/dev/null | sort -nr -t/ -k 7.6,7 | awk -F/ '{ print $7 }' | head -1)
        echo $SUBMGR_REPO
        EOH
end

If I run above command from terminal it works fine as follows:

[c244728_lx@brainiac-ia-0008 redhat]$ SUBMGR_REPO=$(ls -1d /net/gutstools.am.lilly.com/guts_dev/distr/redhat/* | egrep `echo as6-u7_64 | sed -r 's/([aw]s[[:digit:]]+).*$/\1-u[[:digit:]]+(_64)?$/'` 2>/dev/null | sort -nr -t/ -k 7.6,7 | awk -F/ '{ print $7 }' | head -1)
[c244728_lx@brainiac-ia-0008 redhat]$ echo $SUBMGR_REPO
as6-u8_64
[c244728_lx@brainiac-ia-0008 redhat]$ ls

[c244728_lx@brainiac-ia-0008 redhat]$

But fails in chef recipe, it gives null value in $SUBMGR_REPO. Please help me to solve this.

Thanks.

You should really consider refactoring this a bit but I would bet the issue is you have some unescaped backslashes that need fixing (e.g. \\1)
