shell下的进度条和最大最小平均值

进度条

C语言下的进度条参考我原来的一篇blog->进度条

function proc()
{
     i=0 
     str=‘‘
     arr=(‘|‘ ‘/‘ ‘-‘ ‘\\‘)
     index=0
     while [ $i -le 100 ]
     do
         printf "[%-101s][%d%%][%c]\r" "$str" "$i" "${arr[$index]}"                                                                                       
         str=${str}‘#‘
         sleep 0.1
         let i++
         let index++
         let index%=4
     done
     printf "\n"
}
  
function main()
{
    proc
}
main

最大值，最小值，平均值

#!/bin/bash                                                                                                                                              
 
max=0
min=0
count=0
sum=0
while read line
do
    if [ $count -eq 0 ];then
    max=$line
    min=$line
    let count++
    let sum+=$line
    continue
    fi
    [ "$max" -lt "$line" ] && max=$line
    [ "$min" -gt "$line" ] && min=$line
    let sum+=$line
    let count++
done<file

echo $max
echo $min
echo "ibase=10; scale=2; $sum/$count" | bc
