Shell Script to list the Number of Entries Present in Each Subdirectory Mentioned in the Path

In this article, we will discuss how to write a shell script to list the Number of Entries Present in Each Subdirectory Mentioned in the Path

Examples:

Directory: GeeksforGeeks
Subdirectories: GeeksforGeeks/Subdirectory1, GeeksforGeeks/Subdirectory2
Entries in Subdirectory1: gfg.txt, temp.sh
Entries in Subdirectory2: foo.txt, script.sh, pro.exe

Output: ./ Subdirectory1:    2
        ./ Subdirectory2:    3

Script:

# Shell script to count number of entries

# present in subdirectories of a path

# !/bin/sh

find . -maxdepth 1 -type d | while read -r dir

do printf “%s:\t” “$dir”; find “$dir” -type f | wc -l; done

Output:

Explanation:

Each of the lines of this script has been explained below in detail:

• find . -maxdepth 1 -type d: This statement returns a list of all subdirectories present in the current path or directory.
• while read -r dir; do: This statement initiates a while loop as long as the pipe that comes to the while is open.
• printf “%s:\t” “$dir”: This statement will print the string in $dir (that holds one of the directory names) that is followed by a colon and a tab space.
• find “$dir” -type f: Makes the list of all the entries that inside the directory which is held by $dir:
• wc -l: This statement is used to count the number of lines that are passed to the input.
• done: This statement will terminate the while loop.
