 $ man awk
        Patterns are arbitrary Boolean combinations (with ! || &&)  of  regular
        expressions  and relational expressions.  Regular expressions are as in
        egrep; see grep(1).  Isolated regular expressions in a pattern apply to
        the  entire  line.   Regular  expressions  may also occur in relational
        expressions, using the operators ~ and !~.  /re/ is a constant  regular
        expression;  any string (constant or variable) may be used as a regular
        expression, except in the position of an isolated regular expression in
        a pattern.
 
 $ echo 000111 | egrep '^0{3}'
 000111
 $ echo 000111 | awk '/^0{3}/'

 Это очередная бага в авке или я чего-то не понимаю?
