Linux终端头命令问题
我刚刚开始学习Linux终端的基础知识，我遇到了一些问题。我想使用curl或wget下载一个文件并显示其内容，但当我输入head命令时，它会给我html脚本，而不是实际的csv内容。这是我的密码：Linux终端头命令问题,linux,csv,ssh,terminal,command-line-interface,Linux,Csv,Ssh,Terminal,Command Line Interface,我刚刚开始学习Linux终端的基础知识，我遇到了一些问题。我想使用curl或wget下载一个文件并显示其内容，但当我输入head命令时，它会给我html脚本，而不是实际的csv内容。这是我的密码： curl -O http://files.grouplens.org/datasets/movielens/ml-latest-small.zip unzip ml-latest-small.zip head -n 12 movies.csv 以下是返回的内容： <!DOCTYPE html&

有点不对劲。如果这些是您实际运行的命令，并且它们都成功了，那么您下载的文件根本不包含您期望的内容。现在还不清楚为什么从zip文件中提取的CSV文件会包含HTML。此外，这可能更适合于unix.stackexchange.com，因为它更多地处理一些命令行程序的使用，而不是脚本编写。用于编程问题，而不是有关使用或配置Unix及其实用程序的问题。或者是回答类似问题的好地方。大概对OP来说不太明显。起初我没有将CD刻录到新文件中，但我只是这样做了，而且成功了。谢谢。太棒了：）还有-你的命令真的很有用！只运行head-n/ml最新的small/12 movies.csv可能更容易，这样您就不必每次都将CD刻录到其中
