$

if this should be a quoted substitution.var="foo"
echo $"var"
var="foo"
echo "$var"
$".."
is a localized string, for example, echo $"Hello $USER"
along with the proper translation files can be used to have the script say "Bonjour, youruser" in French locales.
In this case, ShellCheck found a localized string whose contents is also the name of a variable. This could have happened because the user wanted a far more common quoted substitution, e.g. "$var"
, but accidentally switched the leading $
and "
.
If you do want a localized string whose contents is also an active variable, you can ignore this warning or rename the variable.
ShellCheck is a static analysis tool for shell scripts. This page is part of its documentation.
