foo={1..9}
echo "$foo"foo="/some/path/*"
echo "$foo"foo=( {1..9} )
echo "${foo[@]}"foo=(/some/path/*)
echo "${foo[@]}"Note that either of these will trigger SC3030 ("In POSIX sh, array

bash.
echo *.png {1..9} expands to all png files and numbers
from 1 to 9, but var=*.png or var={1..9} will

If you intended to assign these values as literals, quote them (e.g.
var="*.png").
