reset - clear all variables of a given name


reset EXPR



Generally used in a continue block at the end of a loop to clear variables and reset ?? searches so that they work again. The expression is interpreted as a list of single characters (hyphens allowed for ranges). All variables and arrays beginning with one of those letters are reset to their pristine state. If the expression is omitted, one-match searches (?pattern?) are reset to match again. Only resets variables or searches in the current package. Always returns 1. Examples:

reset 'X'; # reset all X variables reset 'a-z'; # reset lower case variables reset; # just reset ?? searches

Resetting ``A-Z'' is not recommended since you'll wipe out your ARGV and ENV arrays. Only resets package variables--lexical variables are unaffected, but they clean themselves up on scope exit anyway, so anymore you probably want to use them instead. See my .
