从国际preting prevent的bash没有引述的一切

问题描述

我需要输出一些文本bash脚本，但在一个脚本。我用的猫，但它有一个缺点。它的间$ P $其中pts变量和东西期间，它被写入。我想的 prevent这个

I need to output some text as bash script, but in a script. I use cat for this, but it has one drawback. It interprets variables and stuff during it is being written. I do want to prevent this.

如何做到这一点的没有引用的所有可变因素（我的剧本是failrly长​​）？示例

How to do that without quoting all varibles (my script is failrly long)? Example

cat >/tmp/script << EOF
  $HOSTNAME
  # lots of other stuff I do NOT want to escape like \$VARIABLE
  # ...
EOF

cat /tmp/script
myhostname.mylan

我想：

cat /tmp/script
$HOSTNAME

编辑：请注意我的脚本（这里只的 $ HOSTNAME 的）很长，我不想改变这一切。此外报价单不起作用以＆lt;＆LT;

Please note my script (here only $HOSTNAME) is very long, I dont want to change it all. Also single quoting does not work with <<

cat >/tmp/script '<< EOF
  $HOSTNAME
EOF'
File not found: EOF'

有什么诀窍？谢谢你。

What's the trick? Thanks.

推荐答案

如果你想要的一切报价：

If you want everything quoted:

cat << 'EOF'
stuff here with $signs is OK
as are `backquotes`
EOF
