Here is the simple bash script that uses a “for” loop to list all files in a directory:
Syntax of for loop:
for ((initialization; condition; update)); do
# Commands to be executed in each iteration
done
Here are the steps to create a simple Bash script that uses a for loop to list all files in a directory.
Create a new file as mentioned below.
list_files.sh
Copy and paste below simple Bash script that uses a for loop to list all files in a directory.
# Bash script that uses a “for” loop to list all files in a directory: #!/bin/bash # Specify the directory path directory_path="/path/to/your/directory" # Check if the directory exists if [ -d "$directory_path" ]; then # Use a for loop to iterate over each file in the directory for file in "$directory_path"/*; do # Check if the item is a file (not a directory) if [ -f "$file" ]; then echo "File: $file" fi done else echo "Directory not found: $directory_path" fi
Make sure to replace “/path/to/your/directory” with the actual path of the directory you want to list files from.
Here’s a breakdown of the script:
1. “directory_path=”/path/to/your/directory”“: Set the variable “directory_path” to the path of the directory you want to list files from.
2. “if [ -d “$directory_path” ]; then”: Check if the specified directory exists.
3. “for file in “$directory_path”/*; do”: Use a “for” loop to iterate over each item (file or directory) in the specified directory.
4. “if [ -f “$file” ]; then”: Check if the current item is a file (not a directory).
5. “echo “File: $file”“: If the item is a file, print its name.
6. “fi”: Close the inner “if” statement.
7. “done”: Mark the end of the “for” loop.
8. “else”: If the specified directory doesn’t exist, print an error message.
9. “echo “Directory not found: $directory_path““: Print an error message indicating that the directory was not found.
Run the script by making it executable:
chmod +x list_files.sh
And then execute it:
./list_files.sh
