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

Ls-lr
Long list output file information in this directory (R for subdirectories note the files here, different from the general files, may be directories, links, device files, etc.)

grep "^-"
In this case, the long list output information is filtered, only the general files are preserved, if only the directory is ^d

Wc-l
Statistics output information of the number of rows, because it has been filtered to only the general file, so the statistical results are general file information line number, and because one line of information corresponding to a file, so that is the number of files.

If you view only folders

Ls-d can only display one.
