🎯该 Bash 脚本可生成包含可打印字符的随机密码。用户可通过命令行参数指定密码长度（默认为 9 个字符）和生成的密码数量（默认为 1 个）。脚本通过从 /dev/urandom 读取随机数据，并进行一系列处理来生成密码。

📄作者提供了脚本的下载链接，方便用户获取和使用。同时，还提到了通过特定命令行参数的示例来生成指定长度和数量的密码，如 #randompass.sh 7 7 。

Here I stumbled on an intro into Bash scripting for NetOps by John Kristoff " Introduction to Shell and Perl scripting for Network Operators" https://www.cymru.com/jtk/talks/nanog54-intro-scripting.pdf and could't help but do it my way. Here it is, bash script that generates random password of printable characters, up to 15 at least.

#!/bin/bash# usage: randompass.sh [n] [count]  - n is number of characters in password# to generate 9 by default, and count - number of passwords to generate, 1 by defaultn=${1:-9}counter=${2:-1}for ii in `seq 1 $counter` ;dodd count=1 bs=15  if=/dev/urandom 2>/dev/null |   od -a   | sed '2d'  | sed 's/0000000 \(.*\)/\1/' | tr -d ' '  | cut -c 1-$n | sed 's/\([a-z]\)/\U&/3' | sed 's/\([A-Z]\)/\l&/4'done
