How do I test for a file pattern stored in a variable?

Question

Suppose I have a filename in a variable.

FILENAME_VAR = "1000-Feature.mp4"

What is the bash command I can use to test that the filename in the variable $FILENAME_VAR contains the word Feature?

BTW you can't have spaces around the `=` in a shell assignment. — Gordon Davisson, Jun 12 '13 at 05:23

One way to do it

if [[ $FILENAME_VAR =~ Feature ]]
then
  echo good
else
  echo bad
fi

Steven, I tried your way, but it doesn't seem to work. What I'm testing is to see if the word "Feature" exists in the variable, not in the actual file. – chuacw Jun 12 '13 at 05:28
