For example,Where are your test specs located? (./test/specs/**/*.js)Will that descend in all subdirectories under ./test/specs/, recursively?What authoritative source discusses this wildcard expansion?In the bash man page, I found this bit which seems to contain a typo:globstar  If set, the pattern ** used in a pathname expansion context will match a files and zero or more directories and subdirectories. If the pattern is followed by a /, only directories and subdirectories match.match a files? Really? After 26 years since bash was written?
What does the double star/asterisk wildcard expand to?
