卷曲进度-仅显示百分比 [英] curl progress - only show percentage

问题描述

curl命令是否有一个选项，仅显示输出到shell的百分比而不是全部显示，例如：

Is there an option for the curl command to show only a percentage output to shell rather than all of this, for example:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 12.4M  100 12.4M    0     0  4489k      0  0:00:02  0:00:02 --:--:-- 4653k

也许我可以设置一个标志？如果不是，则通过正则表达式以某种方式将其传递给我，让我仅看到百分比的连续更新？

Maybe there is a flag I can set? If not, pipe it somehow through a regular expression to show me a continuous update of the percentage only?

谢谢所有

推荐答案

两个修饰符可能都可以帮助，尽管两者都不完全相同：-silent 将禁止所有更新，而 --progress-bar 仅显示进度条。

Two modifiers might help, although neither are exact: --silent will suppress all updates and --progress-bar will show a progress bar only.

编辑：一种简化操作的方法是使用期望可简化输出到您的shell脚本或任何正在监听curl的输出。

One option to make things easier would be to make a wrapper using Expect to simplify the output to your shell script or whatever is listening to curl.
