How can I allow uppercase letter with sed?

How can I allow on the following regex the uppercase letters?

Regex is perfectly fine, but it will also rename it if there is uppercase letters on it and I want to allow it.

renamed_file="$(echo "$filename" | sed -e 's/[A-Z]/\L&/g' -e 's/[^a-z0-9]/_/g')"

Modify your regex in sed as followed,

sed -e 's/[^A-Za-z0-9]/_/g'

In this way, any character that doesn't match to A-Za-z0-9 would be converted to _
