Glob syntax
Glob patterns specify sets of filenames with wildcard characters. The most common
wildcards are *, ?, and […]. You can negate any pattern by prefixing it with a
!.
| Wildcard | Description | Example | Matches | Doesn't match |
|---|---|---|---|---|
* | Matches any number of any characters, including none. | Law* *Law* L*aw | Law, Laws, or Lawyer Law, GrokLaw, or Lawyer Law or Laaw | GrokLaw, La, or aw La or aw La or Laws |
? | Matches any single character. | ?at | Cat, cat, Bat, or bat | at |
[abc] | Matches one character given in the bracket. | [CB]at | Cat or Bat | cat, bat, or CBat |
[a-z] | Matches one character from the (locale-dependent) range given in the bracket. | Letter[0-9] | Letter0, Letter1, Letter2, up to Letter9 | Letters, Letter, or Letter10 |
{a,b} | Matches one word given in the braces. | {pass,word} | pass, word | password, passing |
Observability Platform glob syntax doesn't support using two asterisks where one of
them is in the middle of a string. For example, *k8s*staging isn't valid.
