伪随机数生成与唯一文件名创建及浮点数学运算
1. 伪随机数生成与random_number.ksh脚本
在进行一些操作时，我们可能需要生成伪随机数。random_number.ksh脚本可以帮助我们实现这一功能。以下是该脚本的使用示例：
yogi@/scripts# random_number.ksh 32000 10859 yogi@/scripts# random_number.ksh -f 32000 14493 yogi@/scripts# ./random_number.ksh -f 32000 05402 yogi@/scripts# ./random_number.ksh -f ERROR: -f is not a number... USAGE: random_number.ksh [-f] [upper_number_range] EXAMPLE: random_number.ksh Will return a random number between 0 and 32767 EXAMPLE: random_number.ksh 1000 Will return a random number between 1 and 1000 EXAMPLE: random_number.ksh -f 1000 Will add leading zeros to a random number from 1 to 1000, which keeps the number of digits consistent从上述示
