Sort text files in bash - shell

Question

I have a number of text files in the current directory. Each file contains data about a movie.The content of each file will be according to the following format:
Movie name
Storyline
Director name
Year of release
How can I organize the files according to the name of the directors by a shell script. Movies made by same director will get moved to a folder named after the director. How can I do this by writing shell script?

Answer 1

The rough solution will be
for file in *; do
director=$( some code here depending on requirements clarification )
mkdir -p "$director" # quotes are crucial!
# -p suppresses errors if dir already exists.
mv -v "$file" "$director"
done

Answer 2

Assuming that the filename of the movie is always the first line, and the Director name is always the next to last. You could do it something similar to this:
#!/bin/bash
MOVIES_DIR=/path/to/your/movies
for FILE in ${MOVIES_DIR}/*.txt; do
# Movie name will always be the first line
MOVIE=$(sed '1q;d' "$FILE")
# Director will always be the next to last line
DIRECTOR=$(tac "$FILE" | sed '2q;d')
# Make the director folder
mkdir -p "${MOVIES_DIR}/${DIRECTOR}"
# Find inside the `MOVIES_DIR` files with the movie name with any extension
# That is NOT .txt and moves them to the proper director folder.
find "${MOVIES_DIR}" -maxdepth 1 -name "${MOVIE}.*" -not -name '*.txt' -print0 |
while IFS= read -r -d '' NAME; do
FILENAME=$(printf '%s\n' "$NAME")
mv "$FILENAME" "${MOVIES_DIR}/${DIRECTOR}"
done
done
Edit:
It was my misunderstanding that you wanted to move movies with the same name in the text file into the appropriate director folder. I now see you are intending to move the text files themselves. I downloaded all the text files from the link you provided, and it successfully sorted all of them into the appropriate folder:
#!/bin/bash
MOVIES_DIR=/path/to/your/files
for FILE in ${MOVIES_DIR}/*.txt; do
# I thought the description was on one line, but it looks like it can span
# multiple. So get the next to last line instead, since year is only one line. I also changed this in the first script.
DIRECTOR=$(tac "$FILE" | sed '2q;d')
DIRECTOR_PATH="$MOVIES_DIR/$DIRECTOR"
mkdir -p "$DIRECTOR_PATH"
# Move the current text file to the Director folder.
mv "$FILE" "$DIRECTOR_PATH"
done
The first script should sort all movies into the director folders, assuming that the text files are in the same directory as the movies.
The second script should sort all text files into the appropriate director folders.
