Deline is a command-line utility designed to filter out unwanted log entries from files, specifically targeting false positives commonly generated by log scanning tools like SecretFinder. This tool allows users to specify a string; any line containing this string will be omitted from the output, aiding in clearer, more relevant data analysis.

• Filtering Logs: Remove lines that contain specified strings to clean up log files.
• Customization: Fully customizable through command-line arguments to target specific strings.
• Simplicity: Easy-to-use command-line interface.

• Python 3.x

Download the script directly or clone the repository:

git clone https://github.com/heis3nberg-lab/Deline.git

Here is how you can use Deline to filter your logs:

python deline.py --string 'target_string' --input input_file.txt --output output_file.txt

To see a full list of available options:

python deline.py --help

• -str, --string: The string to search for within the log file. Lines containing this string will be removed from the output.
• -i, --input: Path to the input file which contains the log data.
• -o, --output: Path to the output file where the cleaned data will be written.

To filter out lines containing "ERROR" from system.log and save the result to clean_system.log:

python deline.py --string 'ERROR' --input system.log --output clean_system.log
