android - renaming files using adb shell -

i want rename file on android device (running cyanogenmod 11) using adb shell. have access phone via adb, when go directory file located , seek rename mv ./file.old ./file.new mv ./file.old failed, read-only file system. tried same su /system/bin/sh: su: not found

do need alter on phone or somewhere else?

first, cannot rename scheme file directly, if it's scheme file, you'll need superuser permission , you'll have create file scheme read-write. second, on phone type su , grant permission phone.
