对于所有美元值“$X”，我需要将它们替换为“$X/10”（Eks。$2/10=0.2）
我可以使用以下管道命令提取美元值并将它们除以 10：
grep -o '$[[:digit:]]*' dollar.txt | sed 's/[^0-9]//g' | awk '{print /10}'

如何更改整个原始文件（或创建一个新文件）以便文件的其余部分包含所有“$X”值并替换为“$X/10”？
这个的一个实现，作为一个纯 awk 脚本（不需要 bash），可能看起来像：
#!/usr/bin/env awk -f
/[$][[:digit:]]+/ {
while (match([=10=], /[$][[:digit:]]+/) > 0) {
prefix = substr([=10=], 1, RSTART-1)
suffix = substr([=10=], RSTART+RLENGTH)
input = substr([=10=], RSTART+1, RLENGTH-1)
output = input / 10
[=10=] = prefix output suffix
}
}
{ print }
如果 运行 与 ./awkscript <in.txt 或 awk -f awkscript <in.txt，输出为：

说明：我使用 FPAT 通知 GNU AWK 该字段是（0 个或多个数字）或单个任何其他字符。然后我使用 for 循环遍历字段，首先，如果 dollar 变量成立，我将字段替换为 0.1 的值，然后如果字段等于 [=20，我将 dollar 变量设置为 true =].顺序是至关重要的，因为这意味着第一个操作是在美元字段之后立即字段。处理完 I print 行中的所有字段后。我将输出字段分隔符 (OFS) 设置为空字符串，以防止注入不需要的字符。
（在 GNU Awk 5.0.1 中测试）
如果 .2 足以满足 0.2，您可以在每个美元值的最后一位数字前加一个点：
sed -E 's/($)([0-9]*)([0-9])/./g
否则（改进，感谢potong的建议）：
sed -E '
s/$([0-9]+)([0-9])/./g
s/$([0-9])/0./g' file
- 对于包含两位或更多数字的美元值，删除
$ 并在最后一位数字前加一个点（有效除以 10）。
- 任何剩余的美元价值都是一位数字。去掉
$，把0.放在数字前。
- 如果输入已经包含十进制美元值（如
.00），这将不起作用
如果你可以使用 perl 解决这个问题，解决方案将尽可能短
perl -i -pe 's{$(\d+)}{(/10)}ge' file
见online demo。 详情:
-i - 内联文件更改选项s{$(\d+)}{(/10)}ge - s替换命令，其中 RHS（替换部分）是一个 Perl 表达式（使用 e 标志启用），匹配所有（g) 在 $ 符号的每一行上出现，然后是一个或多个数字（捕获到第 1 组，</code>），并将每个匹配项替换为第 1 组值除以的结果10.</li>

<p>如果您想明确禁止执行浮点值替换（例如 <code>.500），您可以将 $(\d+) 替换为 $(\d+)(?!\.?\d)。
