在多个 TXT 文件中将 100 添加到小数

Question

我对此感到困惑，所以需要一些帮助。我在一个文件夹中有多个 txt 文件。这些文本文件中有一些内容。现在有一个文本"moveLimit":30,（逗号在小数点后）。那么我如何将100多个文件中的所有小数添加到十进制并保存它们。移动不是30，它是每个文本文件中的随机数。而且都在10-999之间。

如果您在一开始就说您的txt文件实际上是 JSON 文件（就像您的示例一样） - 它会改变一切并阻止大多数问题/评论。

使用合适的 JSON 工具，jq因为这是正确的方法：

for f in *.txt; do
    if grep -q '"moveLimit":[0-9]*,' "$f"; then
        jq -c '.moveLimit |= . + 100' "$f" > tmp_f && mv tmp_f "$f"
    fi
done
