目前我有一个包含2400个事件的json文件。我试图找到用随机的48个字符的字母数字字符串替换访客ID的最简单方法。
目前我有一个基本文件，其中visitorid看起来像这样
“visitorid”：“$ vids”
我希望使用带有随机48个字符的aplhanumeric字符串的awk替换“$ vids”，看起来像是这样的
“visitorid”：“777048146a3a00a43d480d5a52c00001e007b06600398z82”

您可以使用sha哈希创建一个随机字符串并剪切到所需的大小。
r=$(echo $RANDOM | sha256sum); echo ${r:0:48}

OpenSSL是生成随机字符串的最佳工具。
vids=$(openssl rand -base64 36); echo $vids
lTAyBbCNRu5nOQfmzXtbyWGh5YS2hbiarUdcB3kRJ+sFAcSP
如果一个随机字符串足以替换所有2400个访客ID，那么您可以通过awk选项轻松将随机字符串传递给-v vids="$vids"。
但是，如果您需要为每个访问者ID提供唯一的随机字符串，那么awk并不是完成此任务的最佳工具。
