Create file with contents from shell script
提问by UKB
How do I, in a shell script, create a file called foo.conf and make it contain:
我如何在 shell 脚本中创建一个名为 foo.conf 的文件并使其包含：
NameVirtualHost 127.0.0.1
# Default
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost>

Use a "here document":
使用“此处文档”：
cat > foo.conf << EOF
NameVirtualHost 127.0.0.1
# Default
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost>
EOF

You can do that with echo:
你可以这样做echo：
echo 'NameVirtualHost 127.0.0.1
# Default
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost>' > foo.conf
Everything enclosed by single quotes are interpreted as literals, so you just write that block into a file called foo.conf. If it doesn't exist, it will be created. If it does exist, it will be overwritten.
用单引号括起来的所有内容都被解释为文字，因此您只需将该块写入名为foo.conf. 如果它不存在，它将被创建。如果它确实存在，它将被覆盖。

a heredoc might be the simplest way:
继承人可能是最简单的方法：
cat <<END >foo.conf
NameVirtualHost 127.0.0.1
# Default
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost>
END

This code fitted best for me:
这段代码最适合我：
sudo dd of=foo.conf << EOF
<VirtualHost *:80>
ServerName localhost
DocumentRoot /var/www/localhost
</VirtualHost>
EOF
It was the only one I could use with sudoout of the box!
这是我sudo开箱即用的唯一一款！
