You can compare files in bash and copy them to another folder if they don't exist in the destination folder using the following script:
#!/bin/bash # Set the source and destination directories source_dir=<path_to_source_folder> destination_dir=<path_to_destination_folder> # Get a list of files in the source directory files=$(ls "$source_dir") # Loop through the list of files for file in $files do # Check if the file exists in the destination directory if [ ! -f "$destination_dir/$file" ]; then # If the file does not exist, copy it to the destination directory cp "$source_dir/$file" "$destination_dir/$file" echo "Copied $file to $destination_dir" else echo "$file already exists in $destination_dir" fi done
This script sets the source and destination directories, then gets a list of files in the source directory using the
ls command. It then loops through the list of files, checking if each file exists in the destination directory using the
if statement and the
-f option of the
[ command. If the file does not exist in the destination directory, it is copied using the
cp command. A message is printed indicating whether the file was copied or if it already exists in the destination folder.
