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
