Bash 错误报告

Question

好的，我可以让它运行并将文件放在远程服务器上。但是，当它运行时，我希望它回显“传输失败”、“传输正常”、“文件中的零字节”和“没有这样的文件或目录”。它只是运行代码并发送最后一个条目的电子邮件，当明确文件传输到服务器时，该条目不是这样的文件或目录。我做错了什么？ 提前谢谢你。

Answer 1

您可以使用 /bin/sh -xv yourshellscript.sh 来了解发生了什么。

您可以使用 logger 将重要消息记录到系统日志中

Answer 2

count=$?

if [ $count -eq 0 ]; then 
 echo "$RESULT" "Transfer of file failed. 
 `date`" SBJ="Transfer of file failed `date`" 
else 
 echo "$RESULT" "Transfer OK" 
fi

将结果分配给一个变量，另外，当不需要做更多处理时，尝试使用 exit。
