'bash -c'是做什么的?

我遵循了以下教程:http : //davidtsadler.com/archives/2012/06/03/how-to-install-

magento-on-ubuntu/

在某个时候,它告诉我执行以下命令:

sudo bash -c "cat >> /etc/apache2/sites-available/magento-store.com <<EOF

<VirtualHost *:80>

ServerName localhost.magento-store.com

ServerAlias www.localhost.magento-store.com

DocumentRoot /home/dev/public_html/magento-store.com/public

LogLevel warn

ErrorLog /home/dev/public_html/magento-store.com/log/error.log

CustomLog /home/dev/public_html/magento-store.com/log/access.log combined

</VirtualHost>

EOF"

这个命令做了什么,我该如何取消呢?

我重新启动了计算机,看来它仍在运行。我看了看.bashrc.profile,但没有在里面找到它。

回答:

引用自man bash

   -c string If the -c option is present,  then  commands  are  read  from

string. If there are arguments after the string, they are

assigned to the positional parameters, starting with $0.

您引用的命令会将heredoc中的文本(即,标记中的文本) 附加VirtualHost到文件中/etc/apache2/sites-

available/magento-store.com
