1、elasticsearch启动脚本

1 #!/bin/bash 2 export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64 3 export JAVA_BIN=/usr/java/jdk1.8.0_201-amd64/bin 4 export PATH=$JAVA_BIN:$PATH 5 export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 6 export JAVA_HOME JAVA_BIN PATH CLASSPATH 7 . /etc/init.d/functions  8 function echo_point() 9 {10   min=111   max=212   while [ $min -le $max ]13   do14   for((i=0;i<4;i++))15      do16         printf "."17         sleep 118      done19  min=`expr $min + 1`  20  done21  printf "   "22 }23 24 25 case $1 in26 start)27 28     su - elasticsearch<
     

 

2、循环输出退格省略号

1 #!/bin/sh 2 function start_pro() 3 { 4   min=1 5   max=2 6   while [ $min -le $max ] 7   do 8   for((i=0;i<6;i++)) 9   do10         printf "."11         #printf " "12         #printf "\b"13         sleep 114   done15   tab16  min=`expr $min + 1`  #i++17  #printf $min18  done19  printf "\n"20 }21 22 23 function tab()24 {25   for((i=0;i<6;i++))26   do27         printf "\b"  #退回28         sleep 129   done30 }31 32 33 34 35 case $1 in36         start)37         start_pro38         ;;39         stop)40         echo "stop....."41         ;;42 esac
