Shreddit is a Python command line program which will take a user's post history on the website Reddit, and will systematically go through the user's history deleting one post/submission at a time until only those whitelisted remain. It allows you to maintain your normal reddit account while having your history scrubbed after a certain amount of time.

When it became known that post edits were not saved but post deletions were saved, code was added to edit your post prior to deletion. In fact you can actually turn off deletion all together and just have lorem ipsum (or a message about Shreddit) but this will increase how long it takes the script to run as it will be going over all of your messages every run.

Important New Changes (as of Dec 2016)

Due to deprecation of the PRAW 3.x library, Shreddit is using PRAW 4. This requires that OAuth be used to authenticate. Thankfully, however, it is much easier than in previous versions. If you are upgrading, please review the usage section to ensure that you have set up credentials correctly.

Pip Installation

pip install -U shreddit will install the package and its dependencies, and it will add a shreddit command line utility to your PATH. This is typically either run in a virtualenv or using administrative privileges for global installation.

Manual Installation

  1. Clone the shreddit repository to a directory.
  2. From the directory, run pip install -r requirements.txt
  3. Run python install to install the package and the shreddit command line utility. This is typically either run in a virtualenv or using administrative privileges for global installation.


After installing the shreddit command line utility, the first step is setting up the tool's configuration files. Simply typing shreddit -g will generate configs. After configuring credentials, running the tool with the shreddit command will begin the tool's operation.

Configuring Credentials

Running shreddit -g will generate a blank praw.ini file that looks like this:

# Credentials go here. Fill out default, or provide one or more names and call shreddit with the -u option to specify
# which set to use.

You must provide values for each of these. As strange as it may seem to provide both a username/password pair and a client id/secret pair, that is how the Reddit API does "OAuth" script applications.

Username and password are simply your Reddit login credentials for the account that will be used. However, to obtain the client ID and secret, follow these steps (taken from PRAW documentation):

  1. Open your Reddit application preferences by clicking here.
  2. Add a new application. It doesn't matter what it's named, but calling it "shreddit" makes it easier to remember.
  3. Select "script".
  4. Redirect URL does not matter for script applications, so enter something like
  5. Once created, you should see the name of your application followed by 14 character string. Enter this 14 character string as your client_id.
  6. Copy the 27 character "secret" string into the client_secret field.

Finally, your praw.ini should look like this (with fake data provided here):


Keep your praw.ini either in the current directory when running shreddit, or in one of the config folders described here such as ~/.config in Linux or %APPDATA% in Windows.

To use more than one account, you can add multiple profiles instead of just [default] and use the -u option to shreddit to choose which one each time.


The easiest way to automate this tool after the first run is by using the cron utility. Run crontab -e to edit your user's crontab settings.


The following examples require that the PRAW configuration file is located in the config directory. See this PRAW documentation for more information.

  • Run every hour on the hour 0 * * * * shreddit -c <full path to shreddit.yml>

  • Run at 3am every morning 0 3 * * * shreddit -c <full path to shreddit.yml>

  • Run once a month on the 1st of the month 0 0 1 * * shreddit -c <full path to shreddit.yml>

If virtualenv was used, be sure to add source /full/path/to/venv/bin/activate && before the command. For example:

0 * * * * source /full/path/to/venv/bin/activate && shreddit -c <full path to shreddit.yml>

Command Line Options

$ shreddit --help
usage: [-h] [-c CONFIG] [-g] [-u USER]

Command-line frontend to the shreddit library.

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Config file to use instead of the default shreddit.yml
  -g, --generate-configs
                        Write shreddit and praw config files to current
  -u USER, --user USER  User section from praw.ini if not default

For Windows users

  1. Make sure you have Python installed. Click here for the Python download page. - Note: Install either python 2.x or python 3.x, not both.
  2. Follow the pip installation instructions.
  3. Open a new command prompt and verify that the shreddit command works before moving on to the usage section.


  • Certain limitations in the Reddit API and the PRAW library make it difficult to delete more than 1,000 comments. While deleting >1000 comments is planned, it is necessary right now to rerun the program until they are all deleted.

  • We are relying on Reddit admin words that they do not store edits, deleted posts are still stored in the database they are merely inaccessible to the public.
