创建一个包含100行随机值的文件

python脚本
import random
with open(r'D:\pyt\a.txt','r',encoding='utf-8') as f1,open(r'D:\pyt\a.txt','w',encoding='utf-8') as f2:
    for i in range(101):
        f2.write('%d\n' % random.randint(1,100))

shell脚本
#!/bin/bash
for i in `seq 100`
do
        m=$(echo $RANDOM | md5sum | cut -c 1-6)
        echo "$m" >> testa
done
