sed command using chef

Hi I am using sed command in chef recipe but its throwing error. But If I run just sed command on CLI it works. Any help appreciated.

My sed command is -

sed -i -e "/<BigSQL>/,/<\/BigSQL>/ s|<username>[0-9a-z.]\{1,\}</username>|<username>bigsql</username>|" /home/biadmin/install.xml

And my chef recipe is -

bash "change_bigsqluser" do
user "root"
code <<-EOH
sed -i -e "/<BigSQL>/,/<\/BigSQL>/ s|<username>[0-9a-z.]\{1,\}</username>|<username>bigsql</username>|" /home/biadmin/install.xml
EOH
end

Here is the error 

Error executing action `run` on resource 'bash[change_bigsqluser]'

Since this came up as the first result in Google, I thought I've provide an answer for completeness.

If you look in the compiled resource, the code starts off like this:

sed -i -e \"/<BigSQL>/,/</BigSQL>/

The issue is with escaping. Just change: code <<-EOH to code <<-'EOH':

bash "change_bigsqluser" do
user "root"
code <<-'EOH'
sed -i -e "/<BigSQL>/,/<\/BigSQL>/ s|<username>[0-9a-z.]\{1,\}</username>|<username>bigsql</username>|" /home/biadmin/install.xml
EOH
end

Since you are executing just a single command and you are not using any bash features, I would use an execute resource:

execute "Do some sed" do
    command "sed -i '/<BigSQL>/,/</BigSQL>/ s|<username>[0-9a-z.]{1,}</username>|<username>bigsql</username>|' /home/biadmin/install.xml"
    action :run
end
