比如现在要统计4个命令的输出结果

./xchain-cli status -H 192.168.92.129:37101
    ./xchain-cli status -H 192.168.92.130:37101
    ./xchain-cli status -H 192.168.92.131:37101
    ./xchain-cli status -H 192.168.92.132:37101

提取其中trunkHeight字段的值

vim get_trunkHeight.sh

#!/bin/bash 
    NODES_COUNT=4
    NODES_IP=('192.168.92.129' '192.168.92.130' '192.168.92.131' '192.168.92.132')
    
    i=0
    while [ $i -lt $NODES_COUNT ]
    do
        echo -n "node${NODES_IP[$i]}:";
        ./xchain-cli status -H ${NODES_IP[$i]}:37101 | grep trunkHeight;
        ((i=i+1))
    done
    echo -n "finished"
