shell - shell脚本查找字符串的第一个和最后一次出现

Question

我已经准备了一个Shell脚本，以在50个节点的hadoop集群中执行以下操作:

列出每个服务器中与我的应用程序相关的所有日志文件

打印最后修改的时间戳，主机名，文件名

根据修改的时间戳记

对来自50个节点的日志文件进行排序

当前输出格式为:

2016-07-11-01:06 server1 MY_APPLICATION-worker-6701.log.6.gz
2016-07-12-05:23 server1 MY_APPLICATION-worker-6701.log.7.gz
2016-07-13-08:38 server2 MY_APPLICATION-worker-6701.log
2016-07-13-10:38 server3 MY_APPLICATION-worker-6701.log.out
2016-07-13-10:38 server2 MY_APPLICATION-worker-6701.log.err
2016-07-13-10:38 server5 MY_APPLICATION-worker-6701.log
2016-07-15-10:22 server4 MY_APPLICATION-worker-6703.log.out
2016-07-15-10:22 server3 MY_APPLICATION-worker-6703.log.err
2016-07-15-10:22 server2 MY_APPLICATION-worker-6703.log

。

totallogs=""
for server in $(cat all-hadoop-cluster-servers.txt); do
    logs1="$(ssh user_id@$server 'ls /var/log/hadoop/storm/ -ltr --time-style="+%Y-%m-%d-%H:%M" | grep MY_APPLICATION | awk  -v host=$HOSTNAME "{print \$6, host, \$7}"' )"
    if [ -z "${logs1}"  ]; then
        continue
    else
        logs1+="\n"
        totallogs+=$logs1
    fi  
done
for el in "${totallogs[@]}"
do
    printf "$el"
done | sort

如何在每个日志文件中查找首次出现的“ unique-ID ”和最后一次出现的“ unique-ID ”以及上述输出。

预期的输出格式为:

time_stamp主机名文件名first-unique-ID last-unique-id

2016-07-11-01:06 server1 MY_APPLICATION-worker-6701.log.6.gz    1467005065878   1467105065877

2016-07-13-08:38 server2 MY_APPLICATION-worker-6701.log         1467205065861   1467305065852

2016-07-15-10:22 server4 MY_APPLICATION-worker-6703.log.out     
2016-07-15-10:22 server3 MY_APPLICATION-worker-6703.log.err     
2016-07-15-10:22 server2 MY_APPLICATION-worker-6703.log         1467405065845   1467505065853
