zhengkaike,

you need to have the commands that are called like mount, umount, grep, test, echo and sleep in your rootfs.

maybe it will also work with the busybox versions but i did not test this.

i call the shellscript from the rc script in /etc

for example

automount.sh &

<div align='right'><{post_snapback}> (index.php?act=findpost&pid=16150)

Hi,nacide,

Thank you!

May be my busybox has some bugs,there are many errors when compiled.

I have resolved the problem by using mount() and umount(), it can work successful although it&#39;s not a best method. The code:

<div class='quotetop'>QUOTE </div>

char spe_file[20]="/dev/sda1";

char cur_dir[]="/mnt/usb";

char um_dir[]="/mnt";

char subum_dir[]="usb/";

int main(void)

{

if(mkdir(cur_dir,O_RDWR)==-1)

{

//"/mnt/usb"exsit

if(umount(cur_dir)==-1)

{

printf("erro : umount usb!\n");

exit(1);

}

chdir(um_dir);

if(rmdir(subum_dir)==-1)

{

printf("error rmdir %s \n",subum_dir);

exit(1);

}

printf("umount usb ok!\n");

return 0;

}

if(mount(spe_file,cur_dir,"vfat",2,(char *)NULL)==-1)

{

printf("error :mount");

exit(1);

}

printf("mount usb ok!\n");

return 0;

}[/b]
