[Koha] additional languages

[Araik Manukyan]

Hi list.

I installed koha 3.12.01 version.

After that I tried activate Armenian language via koha-translate -list
command according this 
http://wiki.koha-community.org/wiki/Installation_of_additional_languages_for
_OPAC_and_INTRANET_staff_client  documentation
But I received error
***********************
 kohakoha-translate: command not found
*************************
Where is located that command I can not find them
Any suggestion
Araik
