Check for valid file name with regex

I'm try to verify filenames with this schema: <letter>-<digits>.html. For example, t-32782.html or f-484774.html. One letter then many digits then ".html".

Don't know what flavor of regex you're using, but this should work for a number of them.

/^\w-\d+\.html$/

If the first letter is always lowercase:

/^[a-z]-[0-9]+\.html$/

If it can be lowercase or uppercase:

/^[a-zA-Z]-[0-9]+\.html$/
