helper script for running recovery on an urbit ship. assumes pier is in current directory

run_replay_recovery.sh

#!/bin/bash

DRY_RUN=false
HARD_DELETE=true
#DEL="trash"  # use this if you have trash-cli enabled and don't want to risk the script accidently deleting your precious jam files
DEL="rm"

SHIP_NAME=${1:-"sampel-palnet"} # change this or pass it in as a cmdline input
NUM_EVENTS=${2:-1000000}        # change this or pass it in as a cmdline input
LATEST_EVENT="$(ls ./$SHIP_NAME/.urb/roc/ | cut -d'.' -f1 | sort -nr | head -n1)"


echo "Checkpoint: $LATEST_EVENT"
echo "Recovering $NUM_EVENTS events on ship $SHIP_NAME."

# process a certain number of events

if [ "$DRY_RUN" = true ]; then
        echo ./urbit -r "$LATEST_EVENT" -n "$(($LATEST_EVENT + $NUM_EVENTS))" "$SHIP_NAME"
else
        ./urbit -r "$LATEST_EVENT" -n "$(($LATEST_EVENT + $NUM_EVENTS))" "$SHIP_NAME"
fi
stty sane  # this makes the tty sane lmao


# delete oldest serialized state
JAMCOUNT=$(ls ./"$SHIP_NAME"/.urb/roc/ | wc -l)

if [ $JAMCOUNT -gt 3 ]; then
        echo "deleting some jams"
        ls ./"$SHIP_NAME"/.urb/roc/ | sort -n |  head -n$((JAMCOUNT - 2)) | xargs -I {} "$DEL" ./"$SHIP_NAME"/.urb/roc/{}
fi

Then, to have the script run multiple times use:

bash

for i in {1..10}; do ./run_replay_recovery; done

zsh

repeat 20 ./run_replay_recovery

NO WARRANTY! PLEASE DON'T YELL AT ME IF IT BREAKS YOUR SHIP! HOPEFULLY THIS SCARES YOU ENOUGH TO READ THE SCRIPT FIRST!!!!!
