使用 xargs 时将文本行从输入复制到输出文件

Copy line of text from input to output file while using xargs

我有一个有效的 shell 脚本,它读取一个包含 URL 的文本文件,每个文本文件单独一行。 URLs 从文件中并行读取并检查其状态代码,其中响应写入 status-codes.csv.

如何将url-list.txt引用的原始URL写到status-codes.csv输出的第一列?

状态-codes.sh

#!/bin/bash
xargs -n1 -P 10 curl -u user:pass -L -o /dev/null --silent --head --write-out '%{url_effective},%{http_code},%{num_redirects}\n' < url-list.txt | tee status-codes.csv

url-list.txt

http://website-url.com/path-to-page-1
http://website-url.com/path-to-page-2
http://website-url.com/path-to-page-3

status-codes.csv(当前输出)

http://website-url.com/path-to-page-2,200,1
http://website-url.com/path-to-page-after-any-redirects,200,2
http://website-url.com/404,404,2

status-codes.csv (期望的输出)

http://website-url.com/path-to-page-2,http://website-url.com/path-to-page-2,200,1
http://website-url.com/path-to-page-1,http://website-url.com/path-to-page-after-any-redirects,200,2
http://website-url.com/path-to-page-3,http://website-url.com/404,404,2

使用-I选项。例如:

xargs -n1 -P 10 -I '{}' curl -u user:pass -L -o /dev/null --silent --head --write-out '{},%{url_effective},%{http_code},%{num_redirects}\n' '{}' < url-list.txt | tee status-codes.csv

man xargs:

-I replace-str Replace occurrences of replace-str in the initial-arguments with names read from standard input.
