GLOBBING, AN INTERLUDE
The glob command, short for global, originates in the earliest versions of Bell Labs' Unix[1]. The command interpreters of the early versions of Unix (1st through 6th Editions, 1969–75) relied on a separate program to expand wildcard characters in unquoted arguments to a command: /etc/glob. That program performed the expansion and supplied the expanded list of file paths to the command for execution.
Later, this functionality was provided as a library function, glob(), used by programs such as the shell. - Wikipedia: Glob_(programming)
