ls -l ${re g '\.(sbl|dis)$' *}
Break string up into its constituent characters, putting the result in shell variable x:
x = ${re mg '.|\n' string}
Quote a string s so that it can be used as a literal regular expression without worrying about metacharacters:
s = ${re sg '[*|[\\+.^$()?]' '\\\0' $s}
Define a substitution function pat2regexp to convert shell-style patterns into equivalent regular expressions (e.g. ``?.sbl*'' would become ``^.\.sbl.*$''):
load std subfn pat2regexp { result = '^' ^ ${re sg '\*' '.*' ${re sg '?' '.' ${re sg '[()+\\.^$|]' '\\\0' $*} } } ^ '$' }
