计算终端输出中的行数 [英] count number of lines in terminal output

问题描述

在SO上找不到此.我在终端中运行了以下命令:

couldn't find this on SO. I ran the following command in the terminal:

>> grep -Rl "curl" ./

，并显示出现关键字curl的文件列表.我要计算文件数.我能想到的第一种方法是计算终端中输出的行数.我该怎么办?

and this displays the list of files where the keyword curl occurs. I want to count the number of files. First way I can think of, is to count the number of lines in the output that came in the terminal. How can I do that?

推荐答案

将结果放入 wc 使用-l(行数)开关:

Pipe the result to wc using the -l (line count) switch:

grep -Rl "curl" ./ | wc -l
