/glob/ A mechanism that returns a list of pathnames that match a pattern containing wild card characters. Globbing was available in early versions of Unix and, in more limited form, in Microsoft Windows.
The characters are:
These have become sufficiently pervasive that hackers use them in written messages. E.g. "He said his name was [KC]arl" (expresses ambiguity). "I don't read talk.politics.*" (any of the talk.politics subgroups on Usenet). Other examples are given under the entry for X.
Later Unix shells introduced the x,y,z syntax which expands to a comma-separated list of alternatives, thus foobaz,qux would expand to "foobaz" and "fooqux". This differs from a glob because it generates a list of all possible expansions, rather than matching against existing files.
Glob patterns are similar, but not identical, to regular expressions.
