4个shell写的进度条脚本

example1：

#!/bin/sh
b=''
for ((i=0;$i<=100;i+=2))
do
        printf "progress:[%-50s]%d%%\r" $b $i
        sleep 0.1
        b=#$b
done
echo

效果：

example 2：

 

#!/bin/bash
i=0
while [ $i -lt 20 ]
do
       ((i++))
       echo -ne "=>\033[s"
       echo -ne "\033[40;50H"$((i*5*100/100))%"\033[u\033[1D"
   usleep 50000
done
echo

 效果：

example 3：

 

#!/bin/bash
COUNTER=0
_R=0
_C=`tput cols`
_PROCEC=`tput cols`
tput cup $_C $_R
printf "["
while [ $COUNTER -lt 100 ]
do
    COUNTER=`expr $COUNTER + 1`
    sleep 0.1
    printf "=>"
    _R=`expr $_R + 1`
    _C=`expr $_C + 1`
    tput cup $_PROCEC 101
    printf "]%d%%" $COUNTER
    tput cup $_C $_R
done
printf "\n"

 example 4：

 

#!/bin/bash
i=0
while [ $i -lt 50 ]
do
       ((i++))
        for j in '-' '\\' '|' '/'
        do
       echo -ne "$j\033[s"
       echo -ne "\033[40;50H"$((i*5*100/100))%"\033[u\033[1D"
   usleep 50000
