I'm using fish shell, but here is my env:

$ env | grep OSFONTDIR
OSFONTDIR=/home/gour/.fonts/ /usr/share/fonts/

Now I changed local one to ~/.local/share/fonts, but it is empty and my
fonts are in:

$ fc-cache -v | grep google-noto
	/usr/share/fonts/google-noto
	/usr/share/fonts/google-noto-cjk

Here they are:

$ rm -rf /home/gour/opt/lmtx/tex/texmf-cache/luatex-cache

and I notice that after that 

/home/gour/opt/lmtx/tex/texmf-cache/luatex-cache/ is empty?

My $PATH is:

$ env | grep PATH
PATH=/home/gour/opt/lmtx/bin:/home/gour/opt/lmtx/tex/texmf-linux-64/bin:/home/gour/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin

> 3. Run "context t.tex"

I use the following t.tex

\definefallbackfamily [mainface] [ss] [Noto Sans Devanagari]
   [range={devanagari,devanagariextended},
    features=devanagari-two]

\definefontfamily [mainface] [ss] [Noto Sans]

\setupbodyfont[mainface]

\starttext

ध्यायतो विषयान्पुंसः सङ्गस्तेषूपजायते ।
सङ्गात्सञ्जायते कामः कामात्क्रोधोऽभिजायते ॥ ६२ ॥

dhyāyato viṣayān puṁsaḥ
saṅgas teṣūpajāyate
saṅgāt sañjāyate kāmaḥ
kāmāt krodho ’bhijāyate

\stoptext

as sugested by Wofgang, but it fails:

$ context t.tex 
mtxrun          | unknown script 'mtx-context.lua' or
'mtx-mtx-context.lua'

Do I need to setup some other envvar as it is suggested in the link
posted by Wolfgang?


Sincerely,
Gour
