Hello! Can you tell me what this code does?  #!/bin/bash

# create an empty destination directory if it doesn't exist
mkdir -p /path/to/destination

# get a list of keywords from a file
keywords=$(cat /path/to/keywords)

# loop through all files in the current directory
for file in $(ls)
do
  # check if the filename contains any of the keywords
  if [[ $file =~ ${keywords} ]]; then
    # extract the keyword from the filename
    keyword=$(echo $file | grep -oE '[[:alpha:]]+')
    # create a destination folder for the file
    mkdir -p /path/to/destination/$keyword
    # move the file to the destination folder
    mv $file /path/to/destination/$keyword
  fi
done
