Scheduling exports with Cron

Creating the script

  1. Open Terminal and create a new text file with nano /path/to/DiscordChatExporter/cron.sh

Note: You can't use your mouse in nano, use the arrow keys to control the cursor (caret).

  1. Paste the following into the text file:
#!/bin/bash
# Info: https://github.com/Tyrrrz/DiscordChatExporter/blob/master/.docs

TOKEN=tokenhere
CHANNELID=channelhere
DLLFOLDER=dceFOLDERpathhere
FILENAME=filenamehere
EXPORTDIRECTORY=dirhere
EXPORTFORMAT=formathere
# Available export formats: plaintext, htmldark, htmllight, json, csv
# /\ CaSe-SeNsItIvE /\
# You can edit the export command on line 40 if you'd like to include more options like date ranges and date format. You can't use partitioning (-p) with this script.

# This will verify if EXPORTFORMAT is valid and will set the final file extension according to it. If the format is invalid, the script will display a message and exit.
if [[ "$EXPORTFORMAT" == "plaintext" ]]; then
FORMATEXT=.txt
elif [[ "$EXPORTFORMAT" == "htmldark" ]] || [[ "$EXPORTFORMAT" == "htmllight" ]]; then
FORMATEXT=.html
elif [[ "$EXPORTFORMAT" == "json" ]]; then
FORMATEXT=.json
elif [[ "$EXPORTFORMAT" == "csv" ]]; then
FORMATEXT=.csv
else
echo "$EXPORTFORMAT - Unknown export format"
echo "Available export formats: plaintext, htmldark, htmllight, csv, json"
echo "/\ CaSe-SeNsItIvE /\\"
exit 1
fi

# This will change the script's directory to DLLPATH, if unable to do so, the script will exit.
cd $DLLFOLDER || exit 1

# This will export your chat
./DiscordChatExporter.Cli export -t $TOKEN -c $CHANNELID -f $EXPORTFORMAT -o $FILENAME.tmp

# This sets the current time to a variable
CURRENTTIME=$(date +"%Y-%m-%d-%H-%M-%S")

# This will move the .tmp file to the desired export location, if unable to do so, it will attempt to delete the .tmp file.
if ! mv "$FILENAME.tmp" "${EXPORTDIRECTORY//\"}/$FILENAME-$CURRENTTIME$FORMATEXT" ; then
echo "Unable to move $FILENAME.tmp to $EXPORTDIRECTORY/$FILENAME-$CURRENTTIME$FORMATEXT."
echo "Cleaning up..."
  if ! rm -Rf "$FILENAME.tmp" ; then
  echo "Unable to remove $FILENAME.tmp."
  fi
exit 1
fi
exit 0
  1. Replace:
  • tokenhere with your Token.
  • channelhere with a Channel ID.
  • dceFOLDERpathhere with DCE's directory path (e.g. /path/to/folder, NOT /path/to/folder/DiscordChatExporter.dll).
  • filenamehere with the exported channel's filename, without spaces.
  • dirhere with the export directory (e.g. /home/user/Documents/Discord\ Exports).
  • formathere with one of the available export formats.

Note: Remember to escape spaces (add \ before them) or to quote (") the paths ("/home/my user")!

Note: To save, hold down CTRL and then press O, if asked for a filename, type it and press ENTER. Hit CTRL+X to exit the text editor. Check out this page if you want to know more about nano.

  1. Make your script executable with chmod +x /path/to/DiscordChatExporter/cron.sh

  2. Let's edit the cron file. If you want to run the script with your user privileges, edit it by running crontab -e. If you want to run the script as root, edit it with sudo crontab -e. If this is your first time running this command, you might be asked to select a text editor. Nano is easier for beginners.

  3. Add the following to the end of the file * * * * * /path/to/DiscordChatExporter/cron.sh >/tmp/discordchatexporter.log 2>/tmp/discordchatexportererror.log. Don't forget to replace the /path/to/DiscordChatExporter/cron.sh!

Note: If you don't want logs to be created, replace both /tmp/discordchatexporter.log with /dev/null.

Then replace the *s according to:

Examples:

  • If you want to execute the script at minute 15 of every hour: 15 * * * *
  • Every 30 minutes */30 * * * *
  • Every day at midnight 0 0 * * *
  • Every day at noon 0 12 * * *
  • Every day at 3, 4 and 6 PM 0 15,16,18 * * *
  • Every Wednesday at 9 AM 0 9 * * 3

Verify your cron time here.

Additional information

The week starts on Sunday. 0 = SUN, 1 = MON ... 7 = SUN.

Be aware that if you set the day to '31', the script will only run on months that have the 31st day.

Learn more about running a cron job on the last day of the month here (expert).

The default filename for the exported channel is YYYY-MM-DD-hh-mm-ss-yourfilename. You can change it if you'd like.

Don't forget to update your token in the script after it has been reset!
