Answer 1

Use wc :

(使用wc ：)

wc -l <filename>

This will output the number of lines in <filename> :

(这将输出<filename>的行数：)

$ wc -l /dir/file.txt
3272485 /dir/file.txt

Or, to omit the <filename> from the result use wc -l < <filename> :

(或者，要从结果中省略<filename> ，请使用wc -l < <filename> ：)

$ wc -l < /dir/file.txt
3272485

You can also pipe data to wc as well:

(您也可以将数据传输到wc ：)

$ cat /dir/file.txt | wc -l
3272485
$ curl yahoo.com --silent | wc -l
63
