关于shell脚本用mount和gzip的问题,谢谢了!!!请指教!!!

不死潜龙

1. #!/bin/bash
   
2. mount -o loop -t msdos /home/fydream/makelinux/rhsetup/images/boot.iso /home/fydream/makelinux/mount/bootiso 　　
   
3. gzip -cd /home/fydream/makelinux/mount/bootiso/isolinux/initrd.img > /home/fydream/makelinux/initrd.ext2 　　
   
4. mount -o loop -–t ext2 /home/fydream/makelinux/initrd.ext2 /home/fydream/makelinux/mount/initrdimg

我在shell中挨个的用这及格命令都可以的,但是为什么写成脚本运行就这样了?

1. 
   
2. [root@fydream images]#chmod +x up
   
3. [root@fydream images]# ./up
   
4. Usage: mount -V                 : print version
   
5.        mount -h                 : print this help
   
6.        mount                    : list mounted filesystems
   
7.        mount -l                 : idem, including volume labels
   
8. So far the informational part. Next the mounting.
   
9. The command is `mount [-t fstype] something somewhere'.
   
10. Details found in /etc/fstab may be omitted.
    
11.        mount -a [-t|-O] ...     : mount all stuff from /etc/fstab
    
12.        mount device             : mount device at the known place
    
13.        mount directory          : mount known device here
    
14.        mount -t type dev dir    : ordinary mount command
    
15. Note that one does not really mount a device, one mounts
    
16. a filesystem (of the given type) found on the device.
    
17. One can also mount an already visible directory tree elsewhere:
    
18.        mount --bind olddir newdir
    
19. or move a subtree:
    
20.        mount --move olddir newdir
    
21. A device can be given by name, say /dev/hda1 or /dev/cdrom,
    
22. or by label, using  -L label  or by uuid, using  -U uuid .
    
23. Other options: [-nfFrsvw] [-o options] [-p passwdfd].
    
24. For many more details, say  man 8 mount .
    
25. gzip: /home/fydream/makelinux/mount/bootiso/isolinux/initrd.img.gz: No such file
    
26. or directory
    
27. gzip: 　　.gz: No such file or directory
    
28. mount：无效选项 -- ?
    
29.                     Usage: mount -V                 : print version
    
30.        mount -h                 : print this help
    
31.        mount                    : list mounted filesystems

37.        mount device             : mount device at the known place
    
38.        mount directory          : mount known device here
    
39.        mount -t type dev dir    : ordinary mount command

请指教!

#!/bin/bash -xv
用这个debug模式运行,看看能找到什么问题.

[fydream@fydream images]$ ./up
#!/bin/bash -vx
mount -o loop /home/fydream/makelinux/rhsetup/images/boot.iso /home/fydream/makelinux/mount/bootiso
+ mount -o loop /home/fydream/makelinux/rhsetup/images/boot.iso /home/fydream/makelinux/mount/bootiso $'\343\200\200\343\200\200'
mount: only root can do that
#gzip -cd /home/fydream/makelinux/mount/bootiso/isolinux/initrd.img > /home/fydream/makelinux/initrd.ext2
#mount -o loop -–t ext2 /home/fydream/makelinux/initrd.ext2 /home/fydream/makelinux/mount/initrdimg
出现了这些,但是还是没有挂载上!
