# eosio-tn_bounce is used to restart a node that is acting badly or is down.
# usage: eosio-tn_bounce.sh [arglist]
# arglist will be passed to the node's command line. First with no modifiers
# then with --replay and then a third time with --resync
#
# the data directory and log file are set by this script. Do not pass them on
# the command line.
#
# in most cases, simply running ./eosio-tn_bounce.sh is sufficient.
