我对这个脚本的一致性有一点问题。您可以运行一次，没有任何问题。但是，如果您立即将其重新加载并再次运行，它不会正确获取变量，因为输出没有以正确的方式写入文件。
例如：此实用程序旨在更新 4 个文件。.temp、.tiers、.version 和 .sync 在通过对话框提示的各个阶段，它会更新文件。我的问题是，有时它不会更新文件，我找不到任何原因，因为它只是在你已经运行过一次之后。我在启动时擦除文件，所以我不确定这是什么交易。就好像它只是从记忆中抓取它一样？
无论如何，要对此进行测试，您需要 /test 中的以下文件
感谢任何可以给我一些指导的人。
cat .tiers
Stable=1
Release=2
Beta=3
代码：
#!/usr/bin/env bash
touch .version
touch .temp
VERSION=`cat .version`
DIR=/test/
STORED=`cat ${DIR}/.temp`
