问题描述
我的目录中包含文件数量,需要检查其中的文件数量.
I had a directory with number of files and need to check the count of files present in it.
我尝试了以下两个命令:
I tried the following two commands:
ls | wc -l
ls -l | wc -l
,发现使用这两个命令时存在差异. (即,与第一个命令相比,第二个命令的使用量更大.)
and found there are differences while using both commands. (ie. number of files is greater in the usage of second command while comparing to the first command.)
我想知道两个命令中发生的更改.
I would like to know the changes happening in the both commands.
推荐答案
来自man ls
:
-l (The lowercase letter ``ell''.) List in long format. (See below.) If the output is to a terminal, a total sum for all the file sizes is output on a line before the
long listing.
因此ls -l
添加标题行,指出文件的总"大小:
So ls -l
adds a header line stating the "total" size of files:
$ ls -l /
total 65
