To count number of folders/directories/files in folder/directory is possible using wc command with a parameter -l. But we have to be sure, that we are counting only folders, so let's filter only folder using ls command, and then count then.

Linux command line is very powerful tool even for string and character operations without installing any third-party applications.
To count number of characters in some file, containing text, you can use wc command with -m parameter using following scheme:
$ wc -m <file_name>
Examples:
$ wc -m nata-ubuntu-settings
21 nata-ubuntu-settings
$ wc -m it-slang-v-rustine
1019 it-slang-v-rustine
$ wc -m rongta-files-installation
389 rongta-files-installation
