可以将xargs替换为while循环以避免argument line too long错误。具体修改后的脚本如下：#!binbashcheck_results=redis-cli -c -h $1 -p $2 -a $3 EOFsentinel mastersexitEOFmaster_name=echo $check

可以将代码最后的for循环部分修改为while循环，如下所示：

#!/bin/bash

check_results=redis-cli -c -h $1 -p $2 -a $3 <<EOF sentinel masters exit EOF master_name=echo $check_results | sed -e 's/ip[[:space:]].*//g' -e 's/name//g' -e 's/[[:space:]]//g'

master_ip_port=redis-cli -c -h $1 -p $2 -a $3 <<EOF sentinel GET-MASTER-ADDR-BY-NAME $master_name exit EOF

master_ip=echo $master_ip_port|sed -e 's/[[:space:]].*//g' master_port=echo $master_ip_port|sed -e 's/.*[[:space:]]//g' master_password=$4 OLD_IFS="$IFS" IFS=" " key_list=(${@:5}) IFS=$OLD_IFS echo $key_list total_deleted=0 for key in ${key_list[@]} do echo $key redis-cli -c -h $master_ip -a $master_password -p $master_port --scan --pattern $key | while read redis_key; do result=redis-cli -c -h $master_ip -a $master_password -p $master_port del $redis_key echo $result ((total_deleted+=result)) done done echo "Total number of keys deleted: $total_deleted
