linux中如何统计文本字符的总个数

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
4
2
[root@centos7 test3]# awk '{print length}' test.txt | awk 'BEGIN{sum = 0} {sum += $1} END {print sum}'
10

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}'
10
