Perl some time hank with system command.

[Lim kiang Leng]

I have a problem by using the perl command. Some time it hank with the
system command. such as below.

system ("command") or `command` .


The command that make me hank was ,
`hostname`
system("clear")
system ("mv a b")

can any one tell me, what is the possible reason that cause it hank ?

Define "to hank".

I think the OP means "hang" - where the process just sits there doing
nothing, and fails to terminate.

Cheers,

Define "to hank". This is not a joke: I'm not a native English speaker
and I couldn't find it in my dictionary. May well be slang, but I'm
not familiar with it.

More generally, the description of your problem is too vague: give
more (but reasonably not too many) details.

Have you considered reading the posting guidelines?

`hostname`

As a general rule, do not *ab*use system() and/or qx//. Nothing wrong
IMHO with this one, but maybe you could be interested in Sys::Hostname
anyway...


HTH,

As a native (U.S.) English speaker, I can assure you that 'hank' is
neither proper nor any slang that I've ever heard.

For the record, "Hank" is an English nickname that's short for
"Henry" ("Enrico"). Although I doubt that's what he meant.

If he IS referring to a person's name, his sentence might be better
written as:

which sounds better, but I have no idea who this Hank person would be.

The name "Hank" should not be confused with the word "hanky," which
is short for "hankerchief" ("fazzoletto").

If you think "Hank" is a strange nickname for "Henry," you're not
the only one. After all, even the Homestar Runner said in his
proclamation, "Henceforth, those named Henry will no longer be allowed
to call themselves Hank. That's just too much of a stretch." (This
discussion is getting off-topic, so I'll end it here.)

Hmmm... Let's see if Perl agrees with you.

perl -MText::Soundex -le "print soundex('hank')" H520

perl -MText::Soundex -le "print soundex('hang')"

H520

So, it looks like Perl's Soundex module agrees with you, as both words
return a code of H520.

But there are other words that also have Soundex code H520:

Haines hammock Hans Hanukkah haunch Haynes Heinz
hence Hines hinge homage hong honk Honshu hummock
humus hunch hung hunk Hyannis hying

Maybe the original poster mean that his computer "honks" (or
"beeps") when the system() command is used. But I'm sure you're right,
Rob... he probably mean "hangs." (But if his script were "hying," I'd
really have no idea what he would be talking about...)

One marvels at the fact that the Earth managed to rotate on its own
axis, one revolution per day, *before* Text::Soundex was written ;-)
