/glob/, *not* /glohb/ To expand wild card
characters in a path name
the file name
wild cards are:
* = zero or more characters (E.g. UN*X
? = any single character
 any of the enclosed characters
indicate alternation of comma-separated alternatives, thus foobaz,qux would expand to "foobaz" or "fooqux". This syntax generates a list of all possible expansions, rather than matching one.
These have become sufficiently pervasive that hackers use them in written English, especially in electronic mail
news on technical topics. 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
. Note that glob patterns are similar, but not identical, to those used in regexps.
"glob" was a subprogram that expanded wild cards in archaic pre-Bourne
versions of the Unix shell
