使用shell脚本实现USB设备的加载与文件复制
在Linux操作系统中，如果插入一个USB设备，需要用mount挂载命令才能实现这个设备的加载，下面写一个USB设备挂载与文件复制的Shell程序，程序需求：1、运行时，提示用户输入“y”或者“Y”，确定是否挂载USB设备，U盘文件/dev/sdc1
[*]if[$ANS="Y" -o $ANS = "y"]
[*] then mount -t vfat /dev/sdc1 /mnt/usb
2、确定是否复制文件到/root
最好用$?判断一下是否复制成功，$? -eq 0，表示复制成功
[*]while[$ANS="Y" -o $ANS = "y"]
[*] do
[*] ls -lha /mnt/usb
[*] echo "type the filename you want to copy"
[*] read FILE
[*] cp /mnt/usb/"$FILE" /root
3、确定是否复制文件到USB设备中
[*]echo "Do you want to copy files to USB(y/n)"
[*]read ANS
[*]while[$ANS="Y" -o $ANS = "y"]
[*] do
[*] ls -lh /root
[*] echo "type the filename you want to copy"
[*] read FILE
[*] cp /root/"$FILE" /mnt/usb
[*] if[ $? -eq 0];then
[*] echo "Finished"
[*] else
[*] echo "Error"
[*] fi
[*] echo "any other files(Y/N)"
[*] read ANS
[*] done
完整的脚本：
[*]#!/bin/bash
[*]#autousb
[*]
[*]echo "Welcome to USB"
[*]echo "Do you want load USB(Y/N)"
[*]read ANS
[*]
[*]if[$ANS="Y" -o $ANS = "y"];
[*] then mount -t vfat /dev/sdc1 /mnt/usb
[*] echo "Do you want to copy files to /root(y/n)?"
[*] read ANS
[*] while[$ANS="Y" -o $ANS = "y"]
[*] do
[*] ls -lha /mnt/usb
[*] echo "type the filename you want to copy"
[*] read FILE
[*] cp /mnt/usb/"$FILE" /root
[*] if[ $? -eq 0];then
[*] echo "Finished"
[*] else
[*] echo "Error"
[*] fi
[*] echo "any other files(Y/N)"
[*] read ANS
[*] done
[*]fi
[*]
[*]echo "Do you want to copy files to USB(y/n)"
[*]read ANS
[*]while[$ANS="Y" -o $ANS = "y"]
[*] do
[*] ls -lh /root
[*] echo "type the filename you want to copy"
[*] read FILE
[*] cp /root/"$FILE" /mnt/usb
[*] if[ $? -eq 0];then
[*] echo "Finished"
[*] else
[*] echo "Error"
[*] fi
[*] echo "any other files(Y/N)"
[*] read ANS
[*] done
[*]
[*]echo "Do you want to umount?(y/n)"
[*]read ANS
[*]
[*]
[*]if[$ANS="Y" -o $ANS = "y"];then
[*] umount /mnt/usb
[*]else
[*] echo "umount error"
[*]fi
[*]echo "GoodBye!!"
