I have an sh script and I'm trying to call a python program inside it through an environmental variable but it's returning an error

Script:

#!/system/bin/sh
MN_MOVI="--movie_template '<$title ><($year)><$extension>'" 
mnamer test.mp4 "$MN_MOVI"

Error:

mnamer: error: unrecognized arguments: --movie_template '< ><()><>'

Code works fine with

mnamer test.mp4 --movie_template '<$title ><($year)><$extension>'

Edit --

tripleee linked the correct fix, setting MN_MOVI as an array fixed it

MN_MOVI=(--movie_template '<$title ><($year)><$extension>')
mnamer test.mp4 "${MN_MOVI[@]}"

The double quotes cause the content to be evaluated, not just treated as literals. As there are no matching env vars, you end up with empty brackets. – jonrsharpe Apr 14 '19 at 07:47
Did you export your variables? – MisterMiyagi Apr 14 '19 at 07:47
try mnamer test.mp4 $MN_MOVI, without double quotes around $MN_MOVI. – Anand Apr 14 '19 at 07:49
`/system/bin/sh` looks odd, and definitely isn't [tag:bash] – tripleee Apr 14 '19 at 08:21
Needed to set an array, thanks all! – user5507535 Apr 14 '19 at 16:22
