【问题描述】：
我正在使用 bash 脚本，
当我运行它时
sh mysql-data-add.sh
效果很好，但是当我尝试在后台运行时，它会显示消息
sh mysql-data-add.sh &
-bash: A: command not found
我尝试在 mac 和 centos 服务器上运行。两者的结果相同。我也把它放在cron中，但到目前为止没有结果。但是，当我在没有“&”的情况下使用它时，脚本运行良好
脚本是
cd /home/domainsanalytics/db-new
unzip \*
gunzip \*
ls | grep csv > list.txt

我只想在后台运行脚本。

除了一些奇怪的东西（你真的在你的
db-new目录中有一个字面命名为*的压缩文件吗？），我看不出这样做的目的在后台运行脚本，因为您已经在后台运行了外部循环，并且在进入循环之前没有发生太多事情。除此之外，我会在脚本中打开set -x并将stderr 重定向到某个文件。从此跟踪中，您可以看到是哪一行导致了错误消息，这应该会为您提供一些解决方法的提示。
