java要多思考下

#!/bin/bash
command="keys '*'"
action="noaction"
redis_cli="/usr/local/redis/bin/redis-cli"

if [[ "$1" = "-cmd" ]]; then
    command=$2
fi

if [[  "$3" = "-act"  ]]; then
    action=$4
fi

#collect the command result to an array named results
echo "=====> do command: $command"
exec_command="$redis_cli $command"
results=(`eval $exec_command`)

if [[ ${#results[@]} = 0 ]];then
    exit 1
fi

for (( i = 0; i < ${#results[@]}; i++ )); do
    case $action in
        del)
            doaction="$redis_cli del ${results[i]}"
            ;;
        ttl)
            doaction="$redis_cli ttl ${results[i]}"
            ;;
        expire)
            doaction="$redis_cli expire ${results[i]} 60"
            ;;
        *)
            doaction="echo \"${results[i]}\""
            ;;
    esac
    
    actionResult=`eval $doaction`
    echo "=====> do action: $doaction ==> result: $actionResult"
done

调用形式:
./xxxx.sh -cmd 'keys aa*' -act del
