Commands on HIkey960 board

I have followed the following steps and I think there is linaro version installed on my hikey960 board.

Now my screen looks this way

root@hikey960:~/sush# uname -r
4.14.0-linaro-hikey960
root@hikey960:~/sush# apt-get install perf
-sh: apt-get: not found
root@hikey960:~/sush# yum install perf
-sh: yum: not found
root@hikey960:~/sush#

root@hikey960:~/sush# uname -mrs
Linux 4.14.0-linaro-hikey960 aarch64

root@hikey960:~/sush# compgen -c
-sh: compgen: not found

root@hikey960:~/sush# uname -a
Linux hikey960 4.14.0-linaro-hikey960 #1 SMP PREEMPT Fri Apr 6 10:10:09 UTC 2018 aarch64 aarch64 aarch64 GNU/Linux

I would like to perform installations. What commands can be used as apt-get and yum are incompatible for linaro distributions.
