### Exceptions
If you want `$stuff` to be a literal dollar sign followed by the characters "stuff", you can ignore this message.
If you want `$stuff` to be a literal dollar sign followed by the characters "stuff", you can [[ignore]] this message.
ShellCheck tries to be smart about it, and won't warn when this is used with awk, perl and similar, but there are some inherent ambiguities like `'I have $1 in my wallet'`, which could be "one dollar" or "whatever's in the first parameter".
In the particular case of `sed`, ShellCheck uses additional heuristics to try to separate cases like `'s/$foo/bar/'` (failing to replace the variable `$foo`) with from the false positives like `'$d'` (delete last line). If you're still triggering these, consider being more generous with your spaces: use `$ { s/foo/bar; }` instead of `${s/foo/bar/;}`
