11/25 #!/bin/sh
: How do I make bourne shell subroutine modify a global variable?
: Want to use VAR1 and VAR2 after the subroutine parses my_input_file
foo() {
while read VAR1 VAR2
do
echo "Reading $VAR1 and $VAR2"
export VAR1 VAR2
done < my_input_file
export VAR1 VAR2
}
foo
echo VARS = $VAR1 , $VAR2 # VAR1 & VAR2 are blank/empty-strings!
\_ while loop is executed in a separate shell in bourne shell,
thus its not possible.
\_ wrong. but the order is backwards. Try this.
#!/bin/sh
export GLOBALVAR
GLOBALVAR=1
change(){
GLOBALVAR=2
}
change
echo $GLOBALVAR
\_ too complicted:
#!/bin/sh
change() {
GLOBAL=2;
}
GLOBAL=1;
echo GLOBAL is $GLOBAL
change
echo GLOBAL is $GLOBAL
\_ uh, no you are wrong. In *bourne* shell (virutally
unchanged since AT&T UNIX Version 7) while loops
are a separate process (I'm looking at the code
right now) when the input or output of the shell
is redirected. To avoid this you need to use exec
to save and restore STDIN. Try something like:
#!/bin/sh
myfunc () {
exec 5<&0 < "$1";
while read LINE ;
do
COUNT=`echo $COUNT + 1 | bc`
done
exec 0<&5 5<&-
}
COUNT=0
echo COUNT is $COUNT
myfunc /etc/passwd
echo COUNT is $COUNT
\_ Get new shell.
\_ Stick with Bourne shell as Steve and GOD intended. |

11/25 all you gun control people read this:
http://jacksonville.com/tu-online/stories/112500/met_4711071.html
\_ Actually, the number of incidents involving children shooting
other children at school has been decreasing over the past several
school. really. -tom
years, and is never more than about half a dozen times a year.
assailant was really necessary. -tom
\_ gee I'm sure the cases of kids shooting assailants far outweighs
the cases of kids shooting themselves or shooting up their high
school. really. And I'm also sure that killing the unarmed
assailant was really necessary. Actually it sounds like they
shot him in the back as he was escaping. -tom
\_ If someone enters my property without my permission, he deserves
to die. It doesn't matter if he tries to flee or not. It's a
matter of principle. Some people don't learn to respect property
rights any other way.
\_ Yeah! But for me, if someone enters my property without
my permission. I will first rape her before killing her.
That's my principle, and you need to learn to respect
it.
\_ Its called tresspassing, assault and attempted murder. The son
\_ No, it's called trespassing.
killed a *CRIMINAL* in the act of committing a *CRIME*. He is
the hero, he saved his father's life. Gun control would have
resulted in two dead, the father and the son, while the scum
who murdered them would be one the streets looking for his next
victim (not that this would be a bad thing if his next victim
was TOM).
\_ Lack of gun control has resulted in documented cases of
thouands of innocent people being killed. The idea of
private gun ownership stopping crime is simply too absurd
to respond to. -tom
\_ And there are thousands of documented cases of innocent
people successfully defending themselves. The idea of
private gun ownership not stopping crime is simply
too absurd to respond to.
\_ Add to the list of things NRA syncophants are too
cowardly to do: sign their names. -tom
\_ Yeah, not signing means you're right and I'm
wrong. Let's not bring those other unpleasant
things into this like the f-word: facts. I like
how whenever certain people have nothing to say,
they always fall back on this "you're anonymous,
so your views don't count!" nonsense.
\_ not signing means you're too cowardly to
stand behind your words. -tom
\_ I didn't write either of those posts,
but I support the views expressed in
them. I am not now, nor have I ever
been a gun owner or a NRA member; one
need not own a gun in order to understand
that the RIGHT to keep and bear arms
is fundamental to the preservation of
freedom. ----ranga
\_ Does England not have freedom? -tom
\_ If you want *that* sort of freedom,
you're welcome to it.
No, they don't. The UK has the highest per-capita number of _/
CCTV cameras in the world. There is no equivalent of the bill
of rights, no habeas corpus, and numerous anti-terrorism laws
which permit massive governmental intrusion into what you and I
view as fundamental individual liberties. Guns are banned
completely, with very few specific exceptions. And yet, the UK
has a higher rate of crimes against property and many violent
crimes than the US. No, not what I see as "free". -John
\_ Garbage! Habeas corpus ORIGINATED in England by MEDIEVAL times.
You are a joke!
\_ As did the concept of a written document fundamentally
delineating the powers and responsibilities of rulers towards
their subjects, as a form of contractual terms of office.
That doesn't mean they have one at present... -John
\_ England does not have freedom, Tom.
Recently England jailed a man for
killing a burglar.
\_ ah, so "freedom" includes
"freedom to murder". -tom
\_ We call it self defense.
I suggest that you should
be imprisoned and retrained
for assaulting that poor
guy at the ATM who only
wanted you to share your
wealth.
\_ I don't know, but England did
abolish slavery in the 1830s.
\_ Hello? Modern times? England
still had colonies until the
middle of the 20th century, too.
What's either have to do with
modern England? You're right.
You _don't_ know.
\_ Well ya know what they say... a Republican is a Democrat
that's been mugged. I'm sure Tom will be thrilled to know
the cops will show up 90 minutes later to take a report
after some garbage busts into his house, robs the place,
and beats the shit out of him. Another favorite is "a
young man that isn't liberal has no heart, a grown man
that isn't conservative is a fool".
\_ oh incidentally; I was mugged once, at an ATM in
San Bruno, and fought the guy off. If either of us
had had a gun I might have been shot. -tom
\_ I was mugged and am still a liberal. Also, it is
"old man" not "grown man" in your quote. -ausman
\_ it's also "has no brain" rather than "is
a fool". -tom
\_ Well, what can you expect from someone
with no brain.
\_ Ok, so how exactly would strict guns laws that
keep citizens from arming themselves have kept
your attacker from being armed? Law don't keep
anyone from doing anything. They provide a post-
facto punishment. If he was willing to assault
and rob you, he's already not concerned with
post-crime punishment. And while we're at it,
if you'd had a weapon, you could have apprehended
the criminal so he wouldn't turn on some other
person less able to physically defend themselves.
Thank you for making the streets more dangerous
by teaching a criminal how to better choose his
victims.
\_ Garbage! Gun laws are not for keeping
law-abiding citizens from owning guns.
\_ What? Are you nuts? Who are they written
to keep guns from then? Are you talking
about the U.S. or somewhere else? Of
*course* gun laws are written to keep
law abiding citizens from having guns.
--not NRA member or gun owner but awake
\_ They are written to keep them from
people who want to own guns but
can't or do not want to handle
the responsibilities that goes with
it.
\_ Here's a funny cartoon on the subject:

11/25 perl -i -ep "AnyGivenSunday--OliverStone" s/football stars/programmers/g
and the movie would still be valid. - comments?
\_ Whatever.
\_ That movie sucked really poorly. Oliver Stone is one of the worst
directors in the history of movies. The movie certainly could not
have been worse, whether it was about programmers or even executive
assistants.
\_ Any movie that has eyeballs flying all over the place
is pretty cool. It could have done without the sausage
action, though. -John
\_ Oliver Stone's next movie is going to be a hit: Oliver Stone's
Bill Clinton, staring Richard Gere as Bill, Annette Benning as
Hillary Clinton, Tori Spelling as Monica, Brent Spiner as Al
Gore, Patricia Ruttledge as Madaline Albright, Judi Dench as
Janet Reno. Open parts include: Tipper Gore, Ken Star, Newt,
and First Dyke Chelsea.
\_ John Goodman as Newt, Don Knotts as Ken Starr, Meredith
Baxter Birney as Tipper and Melissa Joan Hart as Chelsea
\_ John Goodman's too tall for Newt. Rush Limbaugh maybe
but not Newt.
MJH is too attractive to be Chelsea, need someone uglier,
like that chick on Boy Meets World.
Don Knotts as Ken Starr, that's pretty funny, though
it might be too funny. Need someone really stiff.
Now who would you get for Joycellen Elders? Mrs. Cosby?
How about Clarence Thomas? |
