This article mainly explains the "Linux system how to count the number of files under the folder", the content of the article is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in-depth, together to study and learn "how to count the number of files under the folder in the Linux system"!

One is:

The code is as follows:

Ls-l | grep "^ -" | wc-l

Description:

Ls-l long list outputs the file information under this directory (note that the files here are different from ordinary files, which may be directories, links, device files, etc.)

Grep ^-here we filter part of the long list output information and keep only the general files. If we only keep the directory, it is ^ d.

Wc-l statistics the number of lines of output information, because it has been filtered to only general files, so the statistical result is the number of lines of general file information, and because one line of information corresponds to a file, that is, the number of files.

View the number of files under the folder (the number of files in the current directory and subfolders)

The code is as follows:

Find. /-type f | wc-l

Or

The code is as follows:

Ls-lR | grep "^ -" | wc-l

The other is:

The code is as follows:

Ls-alR dir_name | awk'{if (NF > 2&&substr)! = "d") print $0}'| wc-l

The strange thing is that there is a slight difference in the number of files counted by the two methods, and the latter is slightly more than the previous one, but there is little difference, which can be used as a reference.
