使用厨师的sed命令

Question

嗨，我在厨师食谱中使用sed命令，但它抛出错误。但是，如果我在CLI上仅运行sed命令，它就可以工作。任何帮助表示赞赏。

我的sed命令是-

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

我的厨师食谱是-

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

这是错误

由于您只执行一个命令，并且没有使用任何bash功能，因此我将使用以下execute资源：

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
