The Collaborative International Dictionary of English v.0.48:

glob \glob\ n.
   1. a compact mass, especially of a semiliquid or viscous
      substance; as, a glob of glue fell on my shoe.

   Syn: ball, clod, lump, clump, chunk.

The Free On-line Dictionary of Computing (17 December 2009):

glob

   /glob/, *not* /glohb/ To expand wild card characters in a
   path name.

   In Unix 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 or
   Usenet 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.

The Jargon File (version 4.4.7, 29 Dec 2003):

glob
 /glob/, not, /glohb/, v.,n.

    [Unix; common] To expand special characters in a wildcarded name, or the
    act of so doing (the action is also called globbing). The Unix conventions
    for filename wildcarding have become sufficiently pervasive that many
    hackers use some of them in written English, especially in email or news on
    technical topics. Those commonly encountered include the following:

    +-------------------------------------------------------------------------+
    |* |wildcard for any string (see also UN*X)                             |
    |--+----------------------------------------------------------------------|
    |? |wildcard for any single character (generally read this way only at the|
    |  |beginning or in the middle of a word)                                 |
    |--+----------------------------------------------------------------------|
    |[]|delimits a wildcard matching any of the enclosed characters           |
    |--+----------------------------------------------------------------------|
    ||alternation of comma-separated alternatives; thus, ?foobaz,qux?     |
    |  |would be read as ?foobaz? or ?fooqux?                                 |
    +-------------------------------------------------------------------------+

    Some examples: ?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.

    Historical note: The jargon usage derives from glob, the name of a
    subprogram that expanded wildcards in archaic pre-Bourne versions of the
    Unix shell.
