file for getting checksums of an entire directory. Usage: "./checksum.sh /path/to/directory /path/to/file/report"

checksum.sh

#!/bin/bash

# Output file to store the SHA256 checksums
output_file="$2"

# Empty the output file if it already exists
> "$output_file"

# Generate a list of all files using 'tree' and process each line
tree -afi --noreport "$1" | while IFS= read -r file; do
    # Check if the path is a regular file
    if [ -f "$file" ]; then
        # Compute SHA256 checksum and append to the output file
        sha256sum "$file" >> "$output_file"
    fi
