Blind Rename files in folder

Bash script to blind rename the files on a folder and saving the new names and old names in a dictionary. Also script to revert file names to original.

Works on OSX and Linux (Debian, Ubuntu, Raspian)

The idea was to obfuscate the file names to properly perform a blind analysis on the files, such as images for quantification.

Now also with GUI, made with Platypus

Characteristics

1. Bash generate pseudo-random new alphanumeric string UPPERCASE and numeric as filename
2. Check if there are too many files in the folder, not practical for manual quantification.
3. Try to avoid big destructive outcomes as it can't be run as superuser or root
4. Ignore name_dictionary.csv and Analysis_file.csv file for renaming
5. Preserve file extension
6. Control if folder have been already randomized by existence of name_dictionary.csv or Analysis_file.csv
7. Check that folder it is in fact a folder and do not goes in subfolders
8. Reduce risk of filename collisions with shasum folder and filename, output cut in half
9. Using the script revert_rename.sh will read the name_dictionary.csv and return the file to their original name
10. Check if folder have been obfuscate before looking for name_dictionary_DEPRECATED.csv
11. Create file with only new names for the manual analysis of the images Analysis_file.csv
12. Insensitive to empty spaces in file names or folder name

Use

• chmod +x bash_blind_rename.sh So it can be executed

• To obfuscate the names on folder temp

./revert_rename.sh folder Dictionary now called name_dictionary_DEPRECATED.csv

TO DO

3. Update DMG image
4. Check for number of files to rename
5. Streamline the script with a function for rename
