Installation
[!NOTE]
- Requires Python 3.11+
Windows & Linux (X11)
pip install crcutil
Linux (Wayland)
[!CAUTION]
- This will add your user to the input group and immediately log you out.
- This makes it possible in Wayland to track keyboard presses; necessary for the playback controls
pip install crcutil
sudo usermod -aG input $USER
sudo pkill -u $USER
MacOS
[!NOTE]
- Enable Accesibility Access for the Terminal on System Settings > Privacy & Security > Accessibility
- This makes it possible in MacOS to track keyboard presses; necessary for the playback controls
pip install crcutil
Usage
crc
Generate CRC32 checksums
[!NOTE]
- This will output a crc.json file in the supplied -o argument.
- If no -o supplied a crc.json is created in the current directory.
- If a crc.json already exists in the current directory, a crc2.json is created.
crcutil crc -l 'C:\path_to_traverse' -o 'C:\path_to_output.json'
[!TIP]
- Make CRCutil run faster by disabling playback controls -f
crcutil crc -f -l 'C:\path_to_traverse'
diff
Diff output can be generated from 2 separate crc files
[!NOTE]
- This will compare both crc files and output a diff.json in the supplied -o argument.
- If no -o supplied a diff.json is created in the current directory.
- If no -l supplied it will look for a crc.json and crc2.json in the current directory
crcutil diff -l 'C:\crc1.json' 'C:\crc2.json' -o 'C:\diff.json'
Pause/Resume
[!CAUTION] The crc can only be resumed as long as the contents/structure of the traversed location have not changed
[!NOTE] To resume a crc after exiting, pass the location of the existing crc to the -o flag
i.e:crcutil crc -l 'C:\path_to_traverse' -o 'C:\existing_crc.json'
- The tool can be paused/resumed at any time by pressing:
- p
- Windows
- Linux (X11)
- MacOS
- alt+p
- Linux (Wayland)
- p
- The tool can be exited at any time by pressing:
