Overview

Iterating over files in a directory is a common task in Bash scripting. Here are a few ways to do it:

1. Using a for loop with wildcard (*): The wildcard (*) character matches any number of characters in a filename. You can use it in a for loop to iterate over all files in a directory.

for file in /path/to/directory/*; do
    echo "$file"
done

This will print the full path of each file in the directory.

2. Using a for loop with find command: The find command is very powerful and can be used to find files based on various criteria. Here’s how you can use it in a for loop:

for file in $(find /path/to/directory -type f); do
    echo "$file"
done

This will print the full path of each file in the directory and its subdirectories. The -type f option tells find to only match files (not directories).

3. Using a while loop with read and find command: If your filenames contain spaces, the above methods will not work correctly. In that case, you can use a while loop with the read command:

find /path/to/directory -type f | while read -r file; do
    echo "$file"
done

This will correctly handle filenames with spaces.

Remember, in these examples, echo "$file" is just a placeholder for whatever operation you want to perform on each file. Replace it with your own command or script.
