This is a very crude attempt in Bash at something that I needed but didn't seem to find in the 'sleep' command. However, I would like to be able to do it without the need for the temp file. Please go easy on me if this is already possible in some other way:

check::isa
Check::ISA(3pm) User Contributed Perl Documentation Check::ISA(3pm)NAME
Check::ISA - DWIM, correct checking of an object's class
SYNOPSIS
use Check::ISA;
if ( obj($foo, "SomeClass") ) {
$foo->some_method;
}
# instead of one of these methods:
UNIVERSAL::isa($foo, "SomeClass") # WRONG
ref $obj eq "SomeClass"; # VERY WRONG
$foo->isa("SomeClass") # May die
local $@; eval { $foo->isa("SomeClass") } # too long
DESCRIPTION
This module provides several functions to assist in testing whether a value is an object, and if so asking about its class.
FUNCTIONS
obj $thing, [ $class ]
This function tests if $thing is an object.
If $class is provided, it also tests tests whether "$thing->isa($class)".
$thing is considered an object if it's blessed, or if it's a "GLOB" with a valid "IO" slot (the "IO" slot contains a FileHandle object
which is the actual invocant). This corresponds directly to "gv_fetchmethod".
obj_does $thing, [ $class_or_role ]
Just like "obj" but uses "DOES" in UNIVERSAL instead of "isa" in UNIVERSAL.
"DOES" in UNIVERSAL is just like "isa", except it's use is encouraged to query about an interface, as opposed to the object structure.
If "DOES" is not overridden by th ebject, calling it is semantically identical to calling "isa".
This is probably reccomended over "obj" for interoperability, but can be slower on Perls before 5.10.
Note that "DOES" in UNIVERSAL
inv $thing, [ $class_or_role ]
Just like "obj_does", but also returns true for classes.
Note that this method is slower, but is supposed to return true for any value you can call methods on (class, object, filehandle, etc).
Look into autobox if you would like to be able to call methods on all values.
obj_can $thing, $method
inv_can $thing, $method
Checks if $thing is an object or class, and calls "can" on $thing if appropriate.
