Find non-empty folders containing Games in their name, print their amount of children and sort the output by number

find -type d -name "*Games*" -not -empty

This part of the command uses the find command to search for directories (-type d) that have "Games" in their name (-name "Games") and are not empty (-not -empty). The find command prints the path of each matching directory to the standard output.

-exec sh -c 'echo "{}: $(expr $(ls -l "{}" | wc -l) - 1)"' \;

This part of the command uses the -exec option of the find command to execute another command on each matching directory. The command to execute is enclosed in single quotes and has a placeholder {} for the directory name. The command ends with a semicolon, which is escaped with a backslash to prevent the shell from interpreting it.

Rename all dirs that contain more than 1 file from Emulator to Emulators (without rename command)

find -type d -name "*Emulator" -not -empty -not -path "*Games*" -exec sh -c 'echo "{}: $(ls "{}" | wc -l)"' \; | awk -F: '$2 > 1' | cut -d: -f1 | xargs -I {} sh -c 'mv "{}" "{}s"'

---

The command is composed of several parts, each separated by a pipe (|) symbol. The pipe symbol means that the output of the previous part is passed as the input to the next part.
