These functions all manipulate strings in various ways. Some more
specialized sections can be found in the regular expression and
<link linkend="ref.url">URL handling</link> sections.

For information on how strings behave, especially with regard to
usage of single quotes, double quotes, and escape sequences, see
the <link linkend="language.types.string">Strings</link> entry in
the <link linkend="language.types">Types</link> section of the
manual.

take a look at the <link linkend="ref.regex">POSIX regular
expression functions</link> and the <link linkend="ref.pcre">Perl
