Some scripts I just finished that I used. Mod variables paths whatever as needed to suit your needs. License is do whatever you want but give credit where credit is due.

Start/Restart server:

#!/bin/bash
#
# Place script in root of minetest run in place and make executable
#
# The startup command expects world to be in rootfolder/world
# Change as needed/wanted

# here I am setting a time stamp variable which I like to use for logging
TIMESTAMP=`date +%Y%m%d.%H%M`

# Logsbak directory
LOGSBAK=`$HOME/.minetest/logsbak`

# Shutdown any running process
kill $(pidof minetestserver)

# Wait
sleep 10

# Cleanup
tar -cvjf ${LOGSBAK}/logback-${TIMESTAMP}.tar.bz2 debug.txt nohup.out
rm debug.txt nohup.out

# Start the server
nohup ./bin/minetestserver --gameid minetest --world world &

# Wait for it to start
sleep 10

# Renice running process to 10
renice 10 $(pidof minetestserver)

echo "All done"

Backup script:

#!/bin/bash
#
# Place script in root of minetest run in place and make executable
#
# Make sure to make directory for worldbackups and alter any variables as needed
#
# The startup command expects world to be in rootfolder/world
# Change as needed/wanted

#terminate minetestserver
kill $(pidof minetestserver)

# Wait
sleep 10

# Variable for logsback directory
LOGSBAK=`$HOME/.minetest/logsbak`

# here I am setting a time stamp variable which I like to use for logging
TIMESTAMP=`date +%Y%m%d.%H%M`

# here I am setting up the backup directory as a variable
DEST_DIR="$HOME/.minetestworldbackups"

# here I am setting up the directory in which I want to backup, again another variable
SRC_DIR="$HOME/.minetest"

# let's create a variable for the backup file name file
FNAME="minetestbackup"

# let's create a variable for the log file, let's also name the log file with the filename and timestamp it
LOG="$HOME/.minetestworldbackups/$FNAME-$TIMESTAMP.log"

# start the backup, create a log file which will record any messages run by this script
echo -e "Starting backup of minetest $SRC_DIR directory" >> ${LOG}

# compress the directory and files, direct the tar.gz file to your destination directory
tar -vczf ${DEST_DIR}/${FNAME}-${TIMESTAMP}.tar.gz ${SRC_DIR} >> ${LOG}

# end the backup, append to log file created by this script
echo -e "Ending backup of minetest $SRC_DIR" >> ${LOG}

# Cleanup
tar -cvjf ${LOGsBAK}/logback-${TIMESTAMP}.tar.bz2 debug.txt nohup.out
rm debug.txt nohup.out

# Start the server
nohup ./bin/minetestserver --gameid minetest --world world &

# Wait
sleep 10

# Renice running process
renice 10 $(pidof minetestserver)

echo "all done.."

I've done a script too. Maybe it will help someone.
It checks for existing minetest process.

1. No minetest started, no pid file -> start
2. minetest started, pidfile already exists -> check for process (NO process existing) -> start new one, overwrite pid file
3. minetest started, pidfile already exists -> check for process (process existing) -> do not start

You can define log file, if empty, it wont create any one.
Maybe you can use it:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all: #!/bin/bash #PARAMETERS #Directory to run in WORKDIR="/home/minetest/minetest-0.4.4-d1-linux" #Pifile PIDFILE="status.pid" # Screen output log SCREENLOG="/dev/null" # how many tries to kill (close) KILL_TIMES="5" # Binary to run MT_BIN="bin/minetestserver" # minetest Game id MT_GAMEID="minetest_game" # empty if no log! MT_LOG="server.log" function start_mt() { if [ -z $MT_LOG ];then nohup $MT_BIN --gameid $MT_GAMEID --logfile '' > $SCREENLOG 2>&1 & else nohup $MT_BIN --gameid $MT_GAMEID --logfile $MT_LOG > $SCREENLOG 2>&1 & fi echo $! > $PIDFILE } function do_start() { if [ -e $PIDFILE ];then kill -0 `cat $PIDFILE` 2>&1 > /dev/null if [ $? -eq 0 ];then echo "MineTest already running! Nothing to do!" else echo "Pidfile found, but no MineTest running!, Starting ..." echo "Starting ..." rm $PIDFILE start_mt fi else echo "Starting" start_mt fi } function do_stop() { if [ -e $PIDFILE ]; then tmp_count="1" kill -0 `cat $PIDFILE` while [ $? -eq 0 ];do if [ $tmp_count -ge 5 ];then kill `cat $PIDFILE` let tmp_count=$tmp_count+1 else kill -9 `cat $PIDFILE` break; fi kill -0 `cat $PIDFILE` done rm $PIDFILE else echo "No Pidfile found, nothing to do!" fi } cd $WORKDIR case $1 in start) do_start;; stop) do_stop;; *) echo "$0 {start|stop}";; esac

I will update status and so on. if someone has any idea to make things better, tell me ;)

Bring on the helpful scripts! lol (can never have too many variations of bash scripts)
