Question

linux

How to pass commands to another console and then close it?
Here is an example:
adb shell
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
chmod 644 "/system/app/Superuser.apk"
chmod 777 "/system/bin/su"
chmod 777 "/system/ xbin/su"
exit
exit
I write everything in bash
but for some reason I don't understand what commands are executed in the current bash but not in the adb shell console how can I fix this?
