How to make a folder with the the month and the day at Unix

is there a way to make do like mkdir monthdate and it make a folder with the the month and the day?

GhostMan, yes
How and create a simlink to do the same thing?
using date +%m

mkdir `date +%m`
check man date for other options
what about creating a simlink to the date
just as you would create a normal sym link and then use a subshell i.e. “ to run date

just as i showed you with mkdir
;-}
sweeet
as I said for a full listting of date options
man date

;-]
is there a way to tell what a simlink for a dir is?
So I can see why its not working
ls -al

inside the ir?
yes
see anything wrong with cp -a /folder /folder/blah/`date +%m%d`
cause that didnt work hmm
errrm

folder/ maybe ?
cp -a testdir/ ./testdir`date +%m%d`
testdir/ is current dir
also ./currentdir

/dir/dir/dir is full path
pwd to check

hmm I cant even get a simlink to work
without the date
GhostMan, works here

Alternate commands for adding users except adduser & useradd

anyone know any alternate commands for adding users, except 'adduser' and 'useradd' ?

useradd is the command
and it's in /usr/sbin
adduser is a symlink to it
oh

hm
I get "bash: adduser: command not found."
any idea why?
su -
I think its FC5

cause you didn't su right
then try it
the little - is important
or use full path

/usr/sbin/useradd blah
"su: user useradd does not exist"
jebus
hah

su -
su - && useradd blah
oh, cool.. thanks

Mount a drive on Unix - Linux so that every user can read it

how can I mount a drive so every user can read it?

chmod the mountpoint
would a dir with the sticky bit set look like: drwxrwxrwt ?
yes

sticky bit just places the t at the end
the other is chmod 777
ah
thanks

How to detect my vga driver at Linux

well it wont detect my vga driver, damnit…?

so you need a better driver to see the better res..
yeah thats the issue
funny how suse and kubuntu both got me higher resolutions than fedora
sigh

i took the entire computer apart
james_: tighter probe setup .. possibly
searched the motherboard for a model number

nothing

the video card is integrated

Divine07: do: lspci
so there's no way to tell what's in there

already tried

generic output
lshw
cmd not found

01:00.0 VGA compatible controller: nVidia Corporation NV18M [GeForce4 448 Go] (rev a2)
/sbin/lspcs
/sbin/lspci
OMG

it gives you all that
Divine07: install it ?

i am, lol

by the way, thankyou for the help

i've been working on this for hours

Cloneable interfaces at Linux

hmm, i dont quite understand what the Cloneable interface is for?

i have an abstract class

with a bunch of sub classes
It's there to indicate that your class is in fact clonable
and some of them are cloneable

so, when trying a clone and wanting to verify that the object is infact cloneable
you get an exception
CloneNotSupportedException, right?
well, no because i know it throws that

i do if (obj instanceof Cloneable)

which determines if the class actually implements the interface
Don't explain java code to me :)
heh sorry

Tell me what the problem is
but what then? i cant seem to call the public clone method without casting it to the specific types implementing cloneable

and a public clone method

i thought the Cloneable interface would actually implement this method so I could use it
Then either implement it on the base class or have something on the base class that delegates the call
easy peasy :)
er.. what?

alright thanks
Interfaces don't implement methods
they declare their existence
yea

what i meant, sorry
or a requirement really
heh

Action: jjava giggles hysterically
your sub-classes that are Clonable, all have to implement the clone()-method
or have one provided for them through a common base class
yea

but then if implementing clone in the base class, i wouldn't know which of the sub classes that actually have a valid clone method

so i'd have to catch the exception of calling clone() ?
er.. they all do in that case
catching the exception is unrelated
CNSE is a check exception and is therefor mandatory to catch and/or re-throw
er.. declare throws
ah alright

thanks
