In this issue, the editor will bring you about how to count the number of files under the folder in the Linux system. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

There are three commands under Linux: ls, grep, and wc. Through the combination of these three commands, you can count the number of files and folders in the directory.

Count the number of files in the current directory (excluding directories)

$ls-l | grep "^ -" | wc-l

Count the number of files in the current directory (including subdirectories)

$ls-lR | grep "^ -" | wc-l

Check the number of folders (directories) under a directory (including subdirectories)

$ls-lR | grep "^ d" | wc-l

Command parsing:

Ls-l

A long list outputs the file information under this directory (note that the files here refer to directories, links, device files, etc.), each line corresponds to a file or directory, and ls-lR lists all files, including subdirectories.

Grep "^ -"

Filter the output of ls, leaving only general files and directories as grep "^ d".

Wc-l

Count the number of lines of output information, the statistical result is the number of lines of output information, one line of information corresponds to a file, so it is the number of files.
