python - 如何使用很多参数执行 python subprocess.Popen？

Question

我需要在本地和远程服务器上执行相同的命令。所以我正在使用 subprocess.Popen 来执行，并且本地命令按预期工作，但是当我在远程执行时它给了我一些错误，比如找不到命令。感谢您的支持，因为我是新手。

本地执行函数

    def topic_Offset_lz(self):
         CMD = "/dsapps/admin/edp/scripts/edp-admin.sh kafka-topic offset %s -e %s | grep -v Getting |grep -v Verifying | egrep -v '^[[:space:]]*$|^#' | awk -F\: '{print $3}'|sed '%sq;d'" % (self.topic,self.envr,self.partition)
         t_out_lz, t_error_lz = subprocess.Popen(CMD, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True).communicate()
         return t_out_lz

远程服务器执行

    def topic_offset_sl(self):
         CMD = "/dsapps/admin/edp/scripts/edp-admin.sh kafka-topic offset %s -e %s | grep -v Getting |grep -v Verifying | egrep -v '^[[:space:]]*$|^#' | awk -F\: '{print $3}'|sed '%sq;d'" % (self.topic, self.envr, self.partition)
         t_out_sl, t_error_sl = subprocess.Popen(["ssh", "-q", CMD], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True).communicate()
         return t_error_sl

远程执行时出错

我提出了以下解决方案，可能会有比这个更简单的方法。

 def topic_offset_sl(self):
        CMD_SL1 = "ssh -q %s '/dsapps/admin/edp/scripts/edp-admin.sh kafka-topic offset %s -e %s'" % (KEY_SERVER,self.topic, self.envr)
        CMD_SL2 = "| grep -v Getting |grep -v Verifying | egrep -v '^[[:space:]]*$|^#' | awk -F\: '{print $3}'|sed '%sq;d'" % (self.partition)
        t_out_sl, t_error_sl = subprocess.Popen(CMD_SL1 + CMD_SL2 , stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True).communicate()
        return t_out_sl
