1、测试数据
[root@centos7 test2]# ll -h total 1.4G -rw-r--r--. 1 root root 41M Apr 15 09:47 a.map -rw-r--r--. 1 root root 204M Apr 15 09:47 a.ped -rw-r--r--. 1 root root 61M Apr 15 09:48 b.map -rw-r--r--. 1 root root 407M Apr 15 09:47 b.ped -rw-r--r--. 1 root root 611M Apr 15 09:47 c.ped -rw-r--r--. 1 root root 21M Apr 15 09:44 result.map
2、统计*.map文件的大小
[root@centos7 test2]# ls *.map | xargs du -ch 41M a.map 61M b.map 21M result.map 121M total [root@centos7 test2]# ls *.map | xargs du -ch | tail -n 1 121M total
ped
[root@centos7 test2]# ls *.ped | xargs du -h 204M a.ped 407M b.ped 611M c.ped [root@centos7 test2]# ls *.ped | xargs du -ch 204M a.ped 407M b.ped 611M c.ped 1.2G total [root@centos7 test2]# ls *.ped | xargs du -ch | tail -n 1
1.2G total
