Like that, you would still need to double quote the variable expansion:
But that would still leave room for partial matches...
Neutronscott made some better suggestions IMO.

LEARN ABOUT NETBSD
sleep
SLEEP(1) BSD General Commands Manual SLEEP(1)NAME
sleep -- suspend execution for an interval of time
SYNOPSIS
sleep seconds
DESCRIPTION
The sleep utility suspends execution for a minimum of seconds. It is usually used to schedule the execution of other commands (see EXAMPLES
below).
Note: The NetBSD sleep command will accept and honor a non-integer number of specified seconds. This is a non-portable extension, and its
use will nearly guarantee that a shell script will not execute properly on another system.
When the SIGINFO signal is received, the estimate of the amount of seconds left to sleep is printed on the standard output.
EXIT STATUS
The sleep utility exits with one of the following values:
0 On successful completion, or if the signal SIGALRM was received.
>0 An error occurred.
EXAMPLES
To schedule the execution of a command for 1800 seconds later:
(sleep 1800; sh command_file >& errors)&
This incantation would wait half an hour before running the script command_file. (See the at(1) utility.)
To reiteratively run a command (with csh(1)):
while (1)
if (! -r zzz.rawdata) then
sleep 300
else
foreach i (*.rawdata)
sleep 70
awk -f collapse_data $i >> results
end
break
endif
end
The scenario for a script such as this might be: a program currently running is taking longer than expected to process a series of files, and
it would be nice to have another program start processing the files created by the first program as soon as it is finished (when zzz.rawdata
is created). The script checks every five minutes for the file zzz.rawdata, when the file is found, then another portion processing is done
courteously by sleeping for 70 seconds in between each awk job.
SEE ALSO at(1), nanosleep(2), sleep(3)STANDARDS
The sleep command is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.
