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!!"
