No, just a ksh substring feature, using file globbing wild cards with meta characters '*', '?', '[...]' but not '[^...]', not regex. It says get the value of animal and chew the end aggressively so as to find the first ':' with the '*'. The '%' means chew on right end, mnemonic: get your percent in the end. # means pound on the nose, chew on the left end. Double ##/%% takes the * from lazy to aggressive. In these cases, aggressive was unnecessary.

For one of my programs, I need to have a hashtable as in Perl. Unfortunately shell doesnt provide any variable like hash. Is there anyway/trick, I could implement a hash in shell (using shell scripts/sed/awk).

Dear Friends,
I want to create a hash table using the standard Glib header (if possible) so that I can store a structure and keep the hash key(search key) based on a string.
Any example code would be great since I am not able to get the main idea.
best regards

regexp::common::balanced
Regexp::Common::balanced(3) User Contributed Perl Documentation Regexp::Common::balanced(3)
NAME
Regexp::Common::balanced -- provide regexes for strings with balanced parenthesized delimiters or arbitrary delimiters.
SYNOPSIS
use Regexp::Common qw /balanced/;
while (<>) {
/$RE{balanced}{-parens=>'()'}/
and print q{balanced parentheses
};
}
DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface.
Do not use this module directly, but load it via Regexp::Common.
$RE{balanced}{-parens}
Returns a pattern that matches a string that starts with the nominated opening parenthesis or bracket, contains characters and properly
nested parenthesized subsequences, and ends in the matching parenthesis.
More than one type of parenthesis can be specified:
$RE{balanced}{-parens=>'(){}'}
in which case all specified parenthesis types must be correctly balanced within the string.
Since version 2013030901, $1 will always be set (to the entire matched substring), regardless whether "{-keep}" is used or not.
$RE{balanced}{-begin => "begin"}{-end => "end"}
Returns a pattern that matches a string that is properly balanced using the begin and end strings as start and end delimiters. Multiple
sets of begin and end strings can be given by separating them by "|"s (which can be escaped with a backslash).
qr/$RE{balanced}{-begin => "do|if|case"}{-end => "done|fi|esac"}/
will match properly balanced strings that either start with do and end with done, start with if and end with fi, or start with case and end
with esac.
If -end contains less cases than -begin, the last case of -end is repeated. If it contains more cases than -begin, the extra cases are
ignored. If either of -begin or -end isn't given, or is empty, -begin => '(' and -end => ')' are assumed.
Since version 2013030901, $1 will always be set (to the entire matched substring), regardless whether "{-keep}" is used or not.
Note
Since version 2013030901 the pattern will make of the recursive construct "(?-1)", instead of using the problematic "(??{ })" construct.
This fixes an problem that was introduced in the 5.17 development track. This also means the pattern is no longer available for Perls
older than 5.010.
