Globs, is associated with certain kinds of 'match this pattern'.
- also called shell globs, because they are mainly seen in command lines
...very simple ones, usually only:
- ? meaning one character of anything, and
- * meaning any amount of characters of anything
- ...anything except the directory separateor, / {{(or presumably \ if imitated in windows)}}
see also fnmatch(), which is a "does a single name match this glob"
whereas glob() both walks your filesystem and returns all matching filenames
- apparently fnmatch() is used in the glob() implementation
Compare with regular expressions, which are more powerful (but still single-string) ways of expressing patterns.
That said:
Some people, when confronted with a problem, think "I know, I'll use regular expressions." Now they have two problems. [1]
