- Group ID--in Unix, the numeric group ID that the operating system uses to identify you and members of your group.
Strictly, the shell's
*character, which will match a "glob" of characters when you're trying to generate a list of filenames. Loosely, the act of using globs and similar symbols to do pattern matching. See also fileglob and typeglob.
- Something you can see from anywhere, usually used of variables and subroutines that are visible everywhere in your program. In Perl, only certain special variables are truly global--most variables (and all subroutines) exist only in the current package. Global variables can be declared with our ( ). See .
- The garbage collection of globals (and the running of any associated object destructors) that takes place when a Perl interpreter is being shut down. Global destruction should not be confused with the Apocalypse, except perhaps when it should.
- A language such as Perl that is good at hooking things together that weren't intended to be hooked together.
- The size of the pieces you're dealing with, mentally speaking.
- A subpattern whose quantifier wants to match as many things as possible.
- Originally from the old Unix editor command for "Globally search for a Regular Expression and Print it", now used in the general sense of any kind of search, especially text searches. Perl has a built-in grep ( ) function that searches a list for elements matching any given criterion, whereas the grep(1) program searches for lines matching a regular expression in one or more files.
- A set of users of which you are a member. In some operating systems (like Unix), you can give certain file access permissions to other members of your group.
- An internal "glob value" typedef, holding a typeglob. The GV type is a subclass of SV.
