在Solaris系统中，通过AWK命令可以实现打印数据文件从第四列到最后一列的全部内容。具体操作是利用nawk，设置空格作为字段分隔符，然后遍历从第四列开始的所有列并打印。给出的AWK语句为：`cat filename | nawk -F " " '{for (i=4;i<=NF;i++)printf("%s ", $i);print ""}'`，执行后会得到格式化的输出结果。" 106350595,7499432,Kafka数据流处理到ES7.7.0常见问题与解决方案,"['大数据开发', 'Spark', 'Kafka', 'Elasticsearch']

数据文件内容如下：

2013/01/21 16:29:07 [158] cd+++++++usr_bin/new/

2013/01/21 16:29:07 [158] cL+++++++ usr_bin/usr_bin/amikeystore ->/usr/bin/amikeystore

目的为打印从第4列到最后一列的内容。主机系统为Solaris。

用如下AWK语句可以实现：

cat filename | nawk -F " " '{for (i=4;i<=NF;i++)printf("%s ", $i);print ""}'

执行后的结果为：

cd+++++++ usr_bin/new/
cL+++++++ usr_bin/new/new -> /usr/bin/new
cd+++++++ usr_bin/usr_bin/
cL+++++++ usr_bin/usr_bin/ControlPanel -> /usr/bin/ControlPanel
cL+++++++ usr_bin/usr_bin/HtmlConverter -> /usr/bin/HtmlConverter
cL+++++++ usr_bin/usr_bin/acctcom -> /usr/bin/acctcom
cL+++++++ usr_bin/usr_bin/adb -> /usr/bin/adb
cL+++++++ usr_bin/usr_bin/addbib -> /usr/bin/addbib
cL+++++++ usr_bin/usr_bin/addgrp -> /usr/bin/addgrp
cL+++++++ usr_bin/usr_bin/admintool -> /usr/bin/admintool
cL+++++++ usr_bin/usr_bin/alias -> /usr/bin/alias
cL+++++++ usr_bin/usr_bin/aliasadm -> /usr/bin/aliasadm
cL+++++++ usr_bin/usr_bin/amiadmin -> /usr/bin/amiadmin
cL+++++++ usr_bin/usr_bin/amicert -> /usr/bin/amicert
cL+++++++ usr_bin/usr_bin/amicertify -> /usr/bin/amicertify
