brandonuv startup script je infinite loop:

while true do blabla done

proto bude lepsi udelat klasicky startup.sh s podminkama zda mtserver bezi, nic nedelat jinak zalohovat a cronem hlidat ten script
(17:24:24) Pitriss: Ritchie_: BTW v cronu se hodí ěnco ve stylu:

''
*/5 *   * * *   minetest    if [ `ps -e | grep -c minetestserver` = '0' ]; then /usr/local/bin/minetest_start.sh; fi
''

minetest_start.sh

#!/bin/bash
 
#This script is used to keep minetestserver running if it crash or stops. Also does backups and creates world map.
