Returns true if the string matches the specified shell expression. Actually, currently the patterns are shell expressions , not regular expressions. Either the second, the third, or both may be left out. If only one parameter is present, the function yeilds a true value on the weekday that the parameter represents. If both wd1 and wd1 are defined, the condition is true if the current weekday is in between those two weekdays.
Bounds are inclusive.
If both values are specified, the result is true between those times, including bounds. Again, even though the above list doesn't show it, this parameter may be present in each of the different parameter profiles, always as the last parameter. All hosts which aren't fully qualified, or the ones that are in local domain, will be connected to directly. If the proxy goes down, connections become automatically direct. Be careful to note the parentheses around the or expression before the and expression to achieve the abovementioned efficient behaviour.
