I'm new to bash, and am asking if I can change the parameter value inside an if statement. However, im getting an error of: attempted assignment to non-variable (error token is "=27-26")

The code i'm running is

if (( $1 > 26 ))
then
    let $1="$1-26"
fi

echo $1

Replace `let $1="$1-26"` with `set -- $(($1-26))`. – Cyrus Mar 27 '21 at 12:16
`set -- "$(( $1 > 26 ? $1 - 26 : $1 ))" "${@:2}"` – Léa Gris Mar 27 '21 at 12:50
