it is giving me this path "/kerl/17.1/bin/erl"

what I feel is that this erl should have been inside /usr/bin/ directory
and instead it is inside
/home/ec2-user//kerl/17.1/bin/erl

So is there any way I can change this path to /usr/bin.
Please tell me if I am thinking right first and if so how can this be done
in linux(amazon linux or fedora).


How about following a guide step by step for Fedora, not OSX. A quick
Google yields some simple instructions.

@ Ranjan,

KERL_ENABLE_PROMPT=Y
. ~/kerl/17.1/activate
They are two separate commands not one command.
Run them one after the other .
After that run
which erl
That command will show you the path to your current activated erlang
version .

home/ec2-user is my home directory or should I say the default directory
when I make the ssh connection to server.
so i ran : KERL_ENABLE_PROMPT=y . ~/kerl/17.1/activate
command when I was in this home directory.
I think I missed a trick here as I am not familiar with linux and how to
set path in linux and that's why maybe when I go to home/ec2-user/download/
ejabberd.17.03/
and run ./configure command it is giving me this error.
what I understand is the line which you are saying that I missed is the
same line as
KERL_ENABLE_PROMPT=y . ~/kerl/17.1/activate
but may be I gave a wrong path or ran it from wrong place (home/ec2-user).
I followed: https://yrsdi.github.io/programming/setup-erlang-with-
kerl-mac-osx/
Can you gauge where I am going wrong exactly

You might miss to run `$ . /path/to/install/dir/activate`.
