1、测试数据
[root@centos7 test3]# ls test.txt [root@centos7 test3]# cat test.txt deet dggh df
2、awk实现
[root@centos7 test3]# ls
test.txt
[root@centos7 test3]# cat test.txt
deet
dggh
df
[root@centos7 test3]# awk '{print length}' test.txt
4

2
[root@centos7 test3]# awk '{print length}' test.txt | awk 'BEGIN{sum = 0} {sum += $1} END {print sum}'

或者：
[root@centos7 test3]# ls
test.txt
[root@centos7 test3]# cat test.txt
deet
dggh
df
[root@centos7 test3]# paste -d "" -s test.txt
deetdgghdf
[root@centos7 test3]# paste -d "" -s test.txt | awk '{print length}'
