Shell 也支持将命令的执行结果赋值给变量，常见的有以下两种方式：
variable=`command` variable=$(command)
通过find命令在/etc目录下查找sources.list文件，将结果赋值给temp变量
temp=`sudo find /etc/ -name sources.list` echo $temp temp=$(sudo find /etc/ -name sources.list) echo $temp
查找路径app/work，如果路径为空不转码，如果不为空转码GBK to UTF-8
sOUT=`find /app/work`;[[$? -eq 0]] && echo $sOUT | iconv -f GBK -t UTF-8
