How to use this index

Entries for language resources refer to Perl ones, unless otherwise indicated—e.g., “NR (AWK)” refers to an AWK resource. As an exception, entries for resources having the same name in the Shell and Perl (e.g., “exit”) apply to both languages unless otherwise indicated.

Entries for metacharacters are found in the Symbols section and refer to resources of the regular expression notation, unless marked as FNG (for filename generation notation).
