any advantages to using pgrep over
trying to parse the output of ps, except for the case when you invoke ps

It gives the same error message no matter what types the function/method

, they do both say they read .ini-style files. I think that they
will both be able to read simple key=value files like the network
definition sysconfig ones on RedHat-style systems that you seem to want.
Keep in mind that the shell probably interprets a bit more, so some
configuration-reading module

The "when" condition within the CATCH block will make it only handle
these exceptions; any other errors will be handled (or passed through) in
their own way.
For more information about exceptions, see the documentation at

So this means that whatever you have in a variable $foo, you may write

I know it's a lot :) Take a look at it, see if you can break it
down into meaningful parts, see how those parts interplay; if you have
any questions, feel free to ask. And, BTW, yes, on my Debian system
this showed a process with ID 29673 running for more than 20 days and
then a process with ID 23280 running for less than thirty minutes, so,
yes, this is what you need, not the largest process ID.
...okay, okay, here goes the very complex line above changed into
a somewhat readable program:
#!/usr/bin/env perl6
use v6.c;
sub pad-elapsed($elapsed) {
my @ints = $elapsed.split(/<[-:]>/).map: *.Int;
my @padded = (0, 0, 0, |@ints);
return @padded[*-4..*];
}
sub is-ours($line) {
$line ~~ /^ \s* $ = [\d+] \s+ "zsh" \s .* \s+ $ = [ <[-
\d :]> + ] $/
?? (~$/ => pad-elapsed $/)
!! Any
}
my @only-ours = $*IN.lines.map();
my @only-real-ones = @only-ours.grep(*.defined);
my @sorted = @only-real-ones.sort(*.value);
my $latest-pid = @sorted[0].key;
say $latest-pid;
Hope that helped!

So you can use a Buf object as an array of whatever it contains.

You just quoted Brad Gilbert's message. Please reread the part that
starts with "If a routine does not declare a return type..." and
goes on until "...of many different types." If the routine's
documentation does not describe its return value, it probably falls
under the "not useful" umbrella. If the documentation does describe
it, there you have it.
Before continuing on this abstract "how do I tell in general" part,
let us know which routines exactly are you wondering right now about.
G'luck,
Peter

So a function that would remove *any* filename extensions, that is,
anything after and including the first dot, would produce really weird
results if applied to filenames created by such people.
