How to Move Files by Partial File Name to New Directory on Mac using a shell script

Streamline Your Photo Editing Workflow: How to Use a Shell Script to Prioritize Selected Images

When it comes to photo editing, efficiency is key. Recently, I faced a challenge where a subject picked out 100 priority photos from a larger batch. Given the sheer number of images, manually sorting them wasn’t practical. All pictures from my SLR were named in the DCIM_# format, so I noted the last five numbers of the selected files. To streamline the process, I wrote a shell script that automatically moves the chosen files to a new folder, allowing me to focus on the priority images first. I’m sharing this script to help others enhance their photo editing workflow.

Step-by-Step Instructions on How to Run a Shell Script

Create the Shell Script:

• Open your favorite text editor (e.g., VSCode, Sublime Text, or even a basic text editor like Notepad).
• Write or paste your shell script. Here’s a simple example for moving selected files:

#!/bin/bash

# Directory containing the files
DIR="{Path}"

# Subfolder to move matching files to
TO_PROCESS_DIR="${DIR}/To Process"

# Ensure the "To Process" directory exists
mkdir -p "$TO_PROCESS_DIR"

# List of substrings to check
substrings=(

)

# Debugging: Check if the directory exists
if [ ! -d "$DIR" ]; then
  echo "Directory $DIR does not exist."
  exit 1
fi

# Debugging: Check if there are files in the directory
if [ -z "$(ls -A "$DIR")" ]; then
  echo "No files found in the directory $DIR."
  exit 1
fi

# Loop through all files in the directory
for file in "$DIR"/*; do
  filename=$(basename "$file")
  echo "Processing file: $filename"
  moved=false
  for substring in "${substrings[@]}"; do
    if [[ "$filename" == *"$substring"* ]]; then
      echo "Found substring '$substring' in file: $filename"
      # Move the file to the "To Process" directory
      mv "$file" "$TO_PROCESS_DIR"
      moved=true
      break
    fi
  done
  if [ "$moved" = false ]; then
    echo "No matching substring found in file: $filename"
  fi
done

Save the Script:

• Save the file with a .sh extension, for example, move_photos.sh.

Make the Script Executable:

• Open a terminal window.
• Navigate to the directory where your script is saved using the cd command. For example:
  

  cd /path/to/your/script

• Make your script executable by running:
  

  chmod +x move_photos.sh

Run the Script:

• Still in the terminal, run your script by typing:
  

  ./move_photos.sh

Verify the Results:

• Check the destination directory to ensure that the files have been moved successfully.

Additional Tips:

• Editing the File List: Modify the FILES array in the script to include the specific last five digits of the filenames you want to move.
• Updating Directories: Ensure that the SOURCE_DIR and DEST_DIR variables are set to the correct paths on your system.

By following these steps, you can efficiently manage and prioritize your photo editing tasks, saving valuable time and effort. This shell script can be customized and expanded to suit various file management needs, making it a versatile tool in your workflow.
