Docker Setup

I have setup the docker container to run the model evaluation.

Output

To modify your `find` command so that it: 1. **Does not overwrite existing `.txt` files**, and 2. **Outputs files with a `.txt` extension instead of `.pdf.txt`** you can use a combination of `find`, `bash`, and conditional checks within a shell command. Here's how you can achieve this: ### Updated Command

find . -name "*.pdf" -exec bash -c '
  for filepath do
    # Construct the output path by replacing the .pdf extension with .txt and prefixing with txt/
    output="txt/${filepath%.pdf}.txt"
    
    # Check if the output file already exists
    if [ ! -f "$output" ]; then
      # Create the necessary directories for the output file
      mkdir -p "$(dirname "$output")"
      
      # Run the Python script with the input and output paths
      python3 process.py "$filepath" "$output"
    fi
  done
' _ {} +
### Explanation of the Command 1. **`find . -name "*.pdf"`**: - Searches recursively in the current directory (`.`) for files ending with `.pdf`. 2. **`-exec bash -c '... ' _ {} +`**: - Executes a `bash` shell for the found files. - The `'_ {} +'` part passes all found files to the shell command efficiently. 3. **Within the `bash` command**: - **Loop Through Each File**: 
1
2
     for filepath do
Iterates over each PDF file found by `find`. - **Construct Output Path**: 
1
2
     output="txt/${filepath%.pdf}.txt"
- `${filepath%.pdf}`: Removes the `.pdf` extension from the filename. - Prefixes the path with `txt/` to place the output in the `txt` directory. - Ensures that the output file has a `.txt` extension instead of `.pdf.txt`. - **Check if Output File Exists**: 
1
2
     if [ ! -f "$output" ]; then
- Skips processing if the `.txt` file already exists, preventing overwriting. - **Create Necessary Directories**: 
1
2
     mkdir -p "$(dirname "$output")"
- Ensures that the directory structure for the output file exists. - **Run the Python Script**: 
1
2
     python3 process.py "$filepath" "$output"
- Processes the PDF and writes the output to the designated `.txt` file. 4. **`done`**: - Ends the loop over the found files. ### Additional Notes - **Handling Directory Structure**: - The above command preserves the directory structure of the input `.pdf` files within the `txt/` directory. For example, `./docs/report.pdf` will be processed into `txt/docs/report.txt`. - **Efficiency**: - Using `+` at the end of `-exec` allows `find` to pass multiple filenames at once to the `bash` command, which is more efficient than running a separate shell for each file. - **Error Handling**: - Ensure that your `process.py` script can handle the inputs correctly and that you have the necessary permissions to create files and directories within the `txt/` directory. ### Alternative Approach Using a Shell Loop If you prefer using a shell loop instead of a single `find` command, you can use the following approach: 
1

find . -name "*.pdf" -print0 | while IFS= read -r -d '' filepath; do
  output="txt/${filepath%.pdf}.txt"
  
  if [ ! -f "$output" ]; then
    mkdir -p "$(dirname "$output")"
    python3 process.py "$filepath" "$output"
  fi
done
- **`-print0` and `-d ''`**: - Handles filenames with spaces and special characters safely. - **Behavior**: - Similar to the `-exec` approach, it processes each `.pdf` file, checks for the existence of the corresponding `.txt` file, and runs the Python script if needed. Choose the method that best fits your workflow and preferences.

Output

To modify your `find` command so that it: 1. **Doesn't overwrite existing `.txt` files** in the `txt/` directory. 2. **Changes the output filename** from `filename.pdf.txt` to `filename.txt`. You can use a combination of `find`, `sh`, and shell scripting to achieve this. Here's how you can do it:

    filename=$(basename "$filepath" .pdf)
    
    # Define the output file path in the txt/ directory
    outfile="txt/${filename}.txt"
    
    # Check if the output file already exists

### Explanation of the Command: 1. **`find . -name "*.pdf"`**: Searches for all `.pdf` files starting from the current directory (`.`). 2. **`-exec sh -c '...' sh {} +`**: - **`sh -c '...'`**: Executes the commands within the single quotes in a shell. - **`sh {}`**: The first `sh` is a placeholder for `$0` inside the `sh -c` command. `{}` represents the current file found by `find`. - **`+`**: This allows `find` to pass multiple filenames to the shell command at once, which is more efficient than running the command separately for each file. 3. **Inside the `sh -c` Script**: - **`for filepath do`**: Iterates over each file path passed to the script. - **`filename=$(basename "$filepath" .pdf)`**: - `basename` extracts the filename from the full path, removing the `.pdf` extension. - For example, `/path/to/document.pdf` becomes `document`. - **`outfile="txt/${filename}.txt"`**: - Constructs the path for the output `.txt` file inside the `txt/` directory. - Using the previous example, this becomes `txt/document.txt`. - **`if [ ! -f "$outfile" ]; then`**: - Checks if the output file **does not** already exist. - **`python3 process.py "$filepath" "$outfile"`**: - If the output file doesn't exist, it runs your `process.py` script with the PDF file as input and the desired `.txt` file as output. - **`fi`**: Ends the `if` statement. - **`done`**: Ends the `for` loop. ### Alternative Single-Line Command If you prefer a more concise, single-line command, you can use the following: 
1
find . -name "*.pdf" -exec sh -c 'outfile="txt/$(basename "$1" .pdf).txt"; [ ! -f "$outfile" ] && python3 process.py "$1" "$outfile"' _ {} \;
**Explanation:** - **`sh -c '...' _ {}`**: - The `_` serves as a placeholder for `$0` inside the script. - `{}` is passed as `$1` to the script. - **`outfile="txt/$(basename "$1" .pdf).txt"`**: - Constructs the output file path by removing the `.pdf` extension and appending `.txt` in the `txt/` directory. - **`[ ! -f "$outfile" ] && python3 process.py "$1" "$outfile"`**: - Checks if the output file does **not** exist. - If it doesn't, runs the `process.py` script. ### Notes: - **Ensure the `txt/` Directory Exists**: Before running the command, make sure that the `txt/` directory exists. You can create it using: 
1
2
  mkdir -p txt
- **Handle Filenames with Spaces**: The provided scripts handle filenames with spaces correctly by quoting variables. - **Performance Consideration**: Using `+` at the end of `-exec` allows `find` to pass multiple files at once to the shell script, which can be more efficient than processing one file at a time with `\;`. However, the single-line alternative uses `\;` and is suitable for simpler use cases. Feel free to choose the method that best fits your workflow and preferences!
