thanks.
If you are just looking to capture the date string in a var, try using the
built in perl functions like:
$date = gmtime();
$date = localtime();
Using perl is also like a combination of shell scripting. If you absolutely
need the string value of the command line "date" program
$date = `date`; # (note the backticks)
The system() function does not do what you are thinking. It is exactly like
exec in shell scripts except it forks first, and then waits for completion of
the task. The return value is not the output of the command.
Basically what you did was tell the interpreter to execute the command 'date'
as if on the command line, and assign that programs return value (which is 0)
to the var $date.
Did you notice that the date output was printed to the screen when you ran the
script?
