1、执行状态处于/旋转
#!/bin/sh
statu_show(){
spin='-\|/'
i=0
while kill -0 $pid 2>/dev/null
do
i=$(( (i+1) %4 ))
printf "\rthe process has running,please waitting...[${spin:$i:1}]"
sleep .1
done
echo
}
sleep 10 &
pid=$! # Process Id of the previous running command
statu_show
2、进度条前进状态
#!/bin/sh
j=''
for ((i=0;$i<=100;i+=2))
do
printf "progress:[%-50s]%d%%\r" $j $i
sleep 0.1
j=#$j
done
echo
3、进度条前进且处于/旋转
#!/bin/bash
i=0
j='#'
k=('|' '\' '-' '/')
l=0
while [ $i -le 25 ]
do
printf "progress:[%-25s][%d%%][%c]\r" $j $(($i*4)) ${k[$l]}
j+='#'
let i++
let l=i%4
sleep 0.1
done
printf "\n"
