The ULTRIX pattern style enables the special interpretation of
   wildcard characters and a quote character in the search-string
   parameter as shown below:

      ULTRIX-Style Wildcards

      Wildcard      Matches

      .             A single character.

      ^             Beginning of a line.

      $             End of a line.

      [set-of-      Any character in the specified set. For example,
      characters]   [abc] matches any letter in the set "abc" and [c-t]
                    matches any letter in the set "c" through "t."

      [^set-of-     Anything not in the specified set of characters.
      characters]

      \             Lets you specify the characters \,.,^,$,[,],or * in
                    wildcard expressions. For example, \\ matches the
                    backslash character (\).

      *             Repeats the previous pattern zero or more times,
                    including the original.

      +             Repeats the previous pattern at least once,
                    including the original; that is, a null occurrence
                    does not match.

   For example the following command will find a line starting with
   a, b or c:

      SEARCH/PATTERN  "^[abc]"
