使用厨师的 sed 命令

Question

您好，我在厨师食谱中使用 sed 命令，但它抛出错误。但是如果我只在 CLI 上运行 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

Answer 1

自从这是谷歌的第一个结果以来，我想我已经提供了一个完整的答案。

如果你查看编译后的资源，代码的开头是这样的：

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

问题在于转义。只需将：code <<-EOH 更改为 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

Answer 2

由于您只执行一个命令并且没有使用任何 bash 功能，我将使用 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
