Linux statistics on the number of files in the folder

Method 1:
Ls-L | grep "^-" | WC-l

The LS-l long list outputs the file information under this directory (note that the file here may be a directory, link, or device file, different from the common file ). If LS-LR | grep "^-" | WC-L is used, the files in the subdirectories can be counted together.

Grep ^-here, a part of the output information of the long list is filtered out, and only the general files are retained. If only the directory is retained, it is ^ d.

WC-l counts the number of rows of output information. Because only common files are available, the statistical result is the number of rows of general files, that is, the number of files.

Method 2:
Find./-type F | WC-l

By default, find will go to the subdirectory to search for files in the current directory.Find./-maxdepth 1-type F | WC-lYou can.

Note that the second method is much faster than the first method, especially when the sub-directories are also counted.
