Slugify a string in bash and copy it to the clipboard. Great for blog filenames.

slugify.sh

# Define the slugify function.
slugify () {
  # Convert the string into a slug and assign it to a variable.
  slug="$(echo "$1" | iconv -t ascii//TRANSLIT | sed -r s/[~\^]+//g | sed -r s/[^a-zA-Z0-9]+/-/g | sed -r s/^-+\|-+$//g | tr A-Z a-z)"

  # Copy the passed variable to system clipboard.
  echo "$slug" | pbcopy

  # Show user the slug and status.
  echo "$slug was copied to your clipboard."
}

# Define the welcome function.
welcome () {
  # Greet system user and prompt for a string.
  echo "Hi, "$USER"! Please enter the string you want to slugify:"

  # Read the string into a variable.
  read string

  # If the string is empty, check prompt again
  if [ -z "$string" ]
  then echo "String was empty. Try again."

  # Call the slugify function, passing the slug as a parameter. Double quote to avoid misparsing.
  else slugify "$string"
  fi
}

# Execute the welcome function.
welcome
