Answer 1

将下面的内容存入文件中，比如test.sh，然后chmod +x test.sh 变成可执行，然后 ./test.sh 99 100 -1 -80 .... 参数可以是任意多数字

#!/bin/bash

if [ -z "$1" ]; then
echo "You have to provide at least one numbers"
exit 1
fi

max=$1
min=$1

for number in $*
do
if [ $number -gt $max ]; then
max=$number
fi

if [ $number -lt $min ]; then
min=$number
fi
done

echo "Max $max, Min $min"
