Hi Folks,

	Since I have not seen any followups or received any e-mail,
probably due to everyone being already on vacation, I add here my
latest experimentation.

	What is the most efficient method to call a system routine
repeatedly and capture it's short output?

	Supposedly, in loop:

#1	system @cmd;

is efficient.  But using backquotes:

#2	(my $sum = `@cmd 2>/dev/null`) =~ s/\s+.*$//;

captures the output correctly, but is horrendously slow, if repeated a
couple of thousand times.  For 35,000 files count about SIX hours!

	Is there a possibility to prepare the fork in #1 in such a way
as to recover the forks output afterwards?  It may help to know that
the output consists only of two numbers.

	In fact, in the above I am using File::Find to recursively
checksum a file structure.  @cmd[0] = '/usr/ucb/sum' and @cmd[1] is
the file path.

	Furthermore, in #2 there is the additional problem that the
shell causes with unusual file names.

	Any suggestions?

	Please do not reply directly to this posting, but use the

	Please reply by e-mail, if at all possible, and I will
summarize to the net if interest warrants.
