SC2125

Brace expansions and globs are literal in assignments. Quote it or use an array.

Problematic code:

foo={1..9}
echo $foo

Correct code:

foo=( {1..9} )
echo "${foo[@]}"

Rationale:

echo *.png {1..9} expands to all png files and numbers from 1 to 9, but var=*.png or var={1..9} will just assign the literal strings '*.png' and '{1..9}'.

To make the variable contain all png files or 1 through 9, use an array as demonstrated.

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

Exceptions

None.
