The GNU C Library provides pattern matching facilities for two kinds of patterns: regular expressions and file-name wildcards. The library also provides a facility for expanding variable and command references and parsing text into words in the way the shell does.
| • Wildcard Matching | Matching a wildcard pattern against a single string. | |
| • Globbing | Finding the files that match a wildcard pattern. | |
| • Regular Expressions | Matching regular expressions against strings. | |
| • Word Expansion | Expanding shell variables, nested commands, arithmetic, and wildcards. This is what the shell does with shell commands. |
