Single user mode character limit ?

I am trying to remove files in single user mode (opened via cmd-S at stat up) but i cannot write the file name since the path to the listed file is long and it goes to the start of the line again and again. is there any character limit for each line?

for example : when i try to wrtie this:

rm /private/var/folders/cd/s5rr8_ujksvghdd87123t2200000gn/0//com.apple.LaunchService-0234.csstore

the cursor goes back to the beginning of line after i wrtie "....LaunchServ"

So I cannot write the command. Thanks in advance for any help.
