不明确的重定向错误

Question 1

您可以使用tee。它从标准输入读取并写入标准输出和文件。

例子：

$ echo foo | tee {1..10}.txt
foo

$ ls
10.txt  1.txt  2.txt  3.txt  4.txt  5.txt  6.txt  7.txt  8.txt  9.txt

$ cat *
foo
foo
foo
foo
foo
foo
foo
foo
foo
foo

另请注意，使用该curl命令您将保存 HTML 页面而不是单独的脚本。您需要获取这些<pre>标签中的所有内容，但这是一个完全不同的问题。

Question 2

您还可以将其分解为多个命令，因为当您第一次开始时更容易理解。例如：

下载文件

$ curl -s http://www.script-o-rama.com/movie_scripts/a1/bee-movie-script-transcript-seinfeld.html -O

上述操作将导致该文件被下载 - bee-movie-script-transcript-seinfeld.html.

将文件复制到 100 个副本

$ for i in {001..100}; do \
    cp bee-movie-script-transcript-seinfeld.html jacob${i}.txt; done

产生这些文件：

$ ls
bee-movie-script-transcript-seinfeld.html  jacob021.txt  jacob042.txt  jacob063.txt  jacob084.txt
jacob001.txt                               jacob022.txt  jacob043.txt  jacob064.txt  jacob085.txt

jacob019.txt                               jacob040.txt  jacob061.txt  jacob082.txt
jacob020.txt                               jacob041.txt  jacob062.txt  jacob083.txt

然后您可以删除原始文件rm -f bee-movie-script-transcript-seinfeld.html.
