Terminal emulator an Android 2.1

I want add new fonts for Android. I found a tutorial that asks me to open a terminal emulator. I can't find this terminal emulator:

On your Droid, open up a terminal emulator application -- I used "Android Terminal Emulator" -- and type this exactly (make sure to be c开发者_如何学JAVAase-sensitive and do not type directions I include in parenthesis):

su (wait for the superuser screen, and press "yes")
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
chmod 4755 /system/fonts/DroidSansFallback.ttf
dd if=/sdcard/DroidSansFallback.ttf of=/system/fonts/DroidSansFallback.ttf
reboot

your android has to be rooted if its not rooted then that permission will come up

I think you are looking for Android Terminal Emulator on Market and github by jackpal.
