python - does #apt-get..... mean the same as sudo apt-get

Question

I'm looking some command line instructions. I'm supposed to have Ubuntu Linux Server with Python 2.7 (and why can't there be a simple explanation of how to get Python 2.7 on your ULS somewhere!). (Edit -- apparently Python 2.7 is built in, my bad!).

One of the first command line instructions is: "#apt-get install build-essential pkg-config git-core python-dev libjpeg62-dev zlib1g-dev libxslt1-dev groff-base"

What does the # symbol mean? Is it a placeholder for sudo?

Answer 1

#只是让您知道该命令应该以超级用户权限执行（即使用sudo，这意味着“超级用户执行”）。它应该代表 root 的默认提示：

root@hostname / # ls -a

而美元符号用于表示非特权用户的提示：

someone@hostname ~ $ ls -a
