The **:FileContent** function near the bottom is where the variable I&#39;m having issues with is.

**!onlineplayer!** is the variable I need to pass a string that may include `!` or `%` to a file via `&gt;&gt;`

Output I want:

    `5John `%Wheeler

Output I get:

    `5John `Wheeler

I need to pipe the value to a text file (PowerShell) for execution at the end of the script.

Everything works correctly, until I use a value containing a `!` or a `%`, then not surprisingly I end up getting empty space where they are supposed to be, normally I would just escape/double `^!` or `%%` but I have no control over the var value and I&#180;m not sure if I should make a new section that tries to inject another `%` into the `txt` file if its detected, or if this already works but just has an expansion issue? I don&#180;t know that an injection route would be easier or without problems.

**得分**: 0
使用延迟扩展将`ECHO $a = "!playername:~5!" >> showonline.ps1` 包裹在`:FILECONTENT`函数中解决了问题。楼主已更新帖子。没有评论的帮助，我无法解决这个问题。谢谢！

<summary>英文:</summary>
Wrapping only a single line in the :FILECONTENT function with delayed expansion resolved the issue. OP updated. I could not have solved this without the comments. Thank you!
