At times like this its a good think to check the jargon file
from jargon file v3.2
----------------------------------------------------------------------
foobar n. <P> Another common metasyntactic variable; see
foo. Hackers do not generally use this to mean FUBAR in
either the slang or jargon sense.
----------------------------------------------------------------------
foo /foo/ <P> 1. interj. Term of disgust. 2. Used very generally as a
sample name for absolutely anything, esp. programs and files (esp.
scratch files). 3. First on the standard list of metasyntactic
variables used in syntax examples. See also bar, baz,
qux, quux, corge, grault, garply,
waldo, fred, plugh, xyzzy, thud.
The etymology of hackish `foo' is obscure. When used in connection
with `bar' it is generally traced to the WWII-era Army slang acronym
FUBAR (`Fucked Up Beyond All Repair'), later bowdlerized to
foobar. (See also FUBAR).
However, the use of the word `foo' itself has more complicated
antecedents, including a long history in comic strips and cartoons.
The old "Smokey Stover" comic strips by Bill Holman often included the
word `FOO', in particular on license plates of cars; allegedly, `FOO'
and `BAR' also occurred in Walt Kelly's "Pogo" strips. In the 1938
cartoon "The Daffy Doc", a very early version of Daffy Duck holds up a
sign saying "SILENCE IS FOO!"; oddly, this seems to refer to some
approving or positive affirmative use of foo. It has been suggested
that this might be related to the Chinese word `fu' (sometimes
transliterated `foo'), which can mean "happiness" when spoken with the
proper tone (the lion-dog guardians flanking the steps of many Chinese
restaurants are properly called "fu dogs").
Paul Dickson's excellent book "Words" (Dell, 1982, ISBN 0-440-52260-7)
traces "Foo" to an unspecified British naval magazine in 1946, quoting
as follows: "Mr. Foo is a mysterious Second World War product, gifted
with bitter omniscience and sarcasm."
Earlier versions of this entry suggested the possibility that hacker
usage actually sprang from "FOO, Lampoons and Parody", the title of a
comic book first issued in September 1958, a joint project of Charles
and Robert Crumb. Though Robert Crumb (then in his mid-teens) later
became one of the most important and influential artists in
underground comics, this venture was hardly a success; indeed, the
brothers later burned most of the existing copies in disgust. The
title FOO was featured in large letters on the front cover. However,
very few copies of this comic actually circulated, and students of
Crumb's `oeuvre' have established that this title was a reference to
the earlier Smokey Stover comics.
An old-time member reports that in the 1959 "Dictionary of the TMRC
Language", compiled at TMRC there was an entry that went
something like this:
FOO: The first syllable of the sacred chant phrase "FOO MANE PADME
HUM." Our first obligation is to keep the foo counters turning.
For more about the legendary foo counters, see TMRC. Almost the
entire staff of what became the MIT AI LAB was involved with TMRC, and
probably picked the word up there.
Very probably, hackish `foo' had no single origin and derives through
all these channels from Yiddish `feh' and/or English `fooey'.
----------------------------------------------------------------------
metasyntactic variable n. <P> A name used in examples and understood
to stand for whatever thing is under discussion, or any random member
of a class of things under discussion. The word foo is the
canonical example. To avoid confusion, hackers never (well,
hardly ever) use `foo' or other words like it as permanent names for
anything. In filenames, a common convention is that any filename
beginning with a metasyntactic-variable name is a scratch file
that may be deleted at any time.
To some extent, the list of one's preferred metasyntactic variables is
a cultural signature. They occur both in series (used for related
groups of variables or objects) and as singletons. Here are a few
common signatures:
foo, bar, baz, quux, quuux, quuuux...:
MIT/Stanford usage, now found everywhere (thanks largely to
early versions of this lexicon!). At MIT (but not at Stanford),
baz dropped out of use for a while in the 1970s and '80s.
A common recent mutation of this sequence inserts qux
before quux.
bazola, ztesch:
Stanford (from mid-'70s on).
foo, bar, thud, grunt:
This series was popular at CMU. Other CMU-associated variables
include gorp.
foo, bar, fum:
This series is reported to be common at XEROX PARC.
fred, barney:
See the entry for fred. These tend to be Britishisms.
corge, grault, flarp:
Popular at Rutgers University and among GOSMACS hackers.
zxc, spqr, wombat:
Cambridge University (England).
shme
Berkeley, GeoWorks, Ingres. Pronounced /shme/ with a short /e/.
foo, bar, zot
Helsinki University of Technology, Finland.
blarg, wibble
New Zealand.
toto, titi, tata, tutu
France.
pippo, pluto, paperino
Italy. Pippo /pee'po/ and Paperino /pa-per-ee'-no/ are the
Italian names for Goofy and Donald Duck.
aap, noot, mies
The Netherlands. These are the first words a child used to
learn to spell on a Dutch spelling board.
Of all these, only `foo' and `bar' are universal (and baz nearly
so). The compounds foobar and `foobaz' also enjoy very wide
currency.
Some jargon terms are also used as metasyntactic names; barf and
mumble, for example. See also Commonwealth Hackish for
discussion of numerous metasyntactic variables found in Great Britain
and the Commonwealth.

Most MUDs are already set up to be stand alone daemons, so you can go
ahead and edit the configuration to be sitting on port 23 (yes that is
correct for telnet). BUT, inetd is already holding that port open for
telnet for you. So, you need to edit your /etc/inetd.conf file and
comment out the stuff for telnet and 'killall -HUP inetd' to restart
the inetd daemon. Then you can go ahead and start up your mud.
(Its up to the individual mud as to what port you configure it to sit
on).
You probably also want to offer telnet in service for maintance on
the machine unless you want to only use it from the console. You can
have inetd run telnet off of other ports by editing your /etc/inetd.conf
as well..

This is clear. With _find_ you get a list of files like _a.lof b.lof ..._
and you can't copy this list to an unspecific filename like *.frm.

I wrote a little shell script which does what you expect.
Maybe some one find a more elegant solution but it works.
--------------------------------------------------------
#!/bin/sh
for FILE in `find . -name "*.lof" -print`
do
# you have to rename each file you have found
NEWFILE=`echo $FILE | sed 's/lof$/frm/g'`
cp $FILE $NEWFILE
echo copied $FILE to $NEWFILE
done

was actually asked during a technical interview, given by a person
who may or may not have known what he was asking: he may have had
the answers that were expected/most correct...I gave him multiple
answers for those questions that differed from Unix to Unix.
BTW, I aced it.
-----
1. What is the name of the program used to make a filesystem?
2. What is the name of the program used to fix a filesystem?
3. What permissions does the command 'chmod 544 filename' establish?
4. What is the name of the program executed to use the Korn Shell?
5. Describe the contents of the /etc/hosts file.
6. What is the format of the /etc/passwd file?
7. What is the cron facility used for?
8. Does the inode of a file contain the file's name?
9. What program is used to set terminal preferences such as how the delete

10. What command establishes the permissions for newly-created files?
11. What file contains the listing of all mounted filesystems?
12. Describe how use of the sticky bit saves system resources.
13. What facility is used to manage how much file space a user can allocate?
14. Can a hard link be created between two filesystems?
15. How does the system know that a file is to be executed with the Bourne

The only way to do it would be to execute rsh on another system. This
requires you to setup your .rhosts file. You should NOT put ANY wildcards
into your .rhosts file, as that is a security risk. It would look something
like this..
icicle.winternet.com static
parka.winternet.com static
klondike.winternet.com static
subzero.winternet.com static
Ie. hostname of safe host, and username on that host. It goes into your main
home directory.
Then the format of the rsh command is
rsh machinename command-to-execute command-params
For what you want to do its
rsh parka ps -gu
rsh klondike ps -gu
rsh subzero ps -gu
which will give you all the output of those commands executed on parka,
klondike, and subzero. It does take a little bit longer to execute a
command over the net..

finger gives out information. Weather that information is valuable to

With the spoffing of .plan and .project files finger can be a problem.
e.g. if I can write to your .plan file and pipe through a shell,
I could have you send me the password file anytime I fingered the account.
The in.fingerd has also been on of the more commonly trojaned services.

funny, in doing broad analysis of clients internal networks I still

It may be 99% irrelevant (read;dead hole) but like most things in

That is okay, ":" is, well, your delimiter and to replace it you have to
use another command like in ...
cut -d: -f1,6,7 /etc/passwd | tr ":" " "
... or ...
cut -d: -f1,6,7 /etc/passwd | sed -e 's/:/ /g'=20

A tab. But you have to quote it so that the shell doesn't
simply eat it, for example:
sort -frbt' ' +1 test.dat
Between the two quote marks ('s) is a single tab character.
If you're doing this in an interactive shell, and depending
on exactly what shell you are using, you might also have to
type a Control-V character before the tab character.
(N.B.: I actually would have escaped the tab with a \, but that
is too visually ambiguous for a Usenet posting:
sort -frbt\ +1 test.dat
That's a backslash, tab, space between the "t" and the "+".)

It might be noted that the default field separator character(s) is
whitespace (tabs or spaces or a combination of both), but if your
delimiter is tabs (because of embedded whitespace in what you call
your fields), Ken's approach is proper rather than not using the
-t option.

To split the file into chunks that will fit on a floppy do the
following:
"split -b 1400000 <filename>"
split files will be called xa, xb, xc, etc.
to create smaller chunks, just change 1400000 to what ever you want
To join them back together
"cat x* > original_filename "

Geberally speaking, and assuming your mouse is actually working, is
hooked up properly, and you've the correct protocol selected for it, there
are three ways to get the mouse to actually work in X:
1) You can kill gpm with (as root) gpm -k (or killall gpm), then
start your X session as normal. For many reasons, this is not an optimal
solution;
or 2) you can edit the file /etc/rc.d/rc.local (from which gpm is
started), remove the -R flag, reboot, and restart your X session (this is
what I've done);
or 3) if there is an -R flag present in the gpm cmd line, you can
leave it and edit the file /etc/XF86Config, paying attn to the section
dealing with the Pointer device, as shown below:
[segment of my /etc/XF86Config]
# **********************************************************************
# Pointer section
# **********************************************************************
Section "Pointer"
Protocol "Microsoft"
Device "/dev/mouse"
See the line dealing with 'Device?' Change that from /dev/mouse to
/dev/gpmdata, save and restart X. (This is actually the preferred method,
although #2 works as well.)
What's happening is gpm (which is more of a daemon than not)
intercepts all mouse movement events and sends them to the file /dev/mouse,
EXCEPT when the -R flag is present, when it sends them to /dev/gpmdata. The
X config file (/etc/XF86Config) tells X to look for mouse movement events in
/dev/mouse -- but they are being put in /dev/gpmdata and since the X server
doesn't know to look there, well.. It makes no difference what kind of
pointer device you have -- serial, bus, ps/2, or whatever.
From man gpm:
-R Causes gpm to act as a repeater: any mouse data
received while in graphic mode will be produced on
the fifo /dev/gpmdata ... .
HTH.

Hi
yup its called chroot.
edit the homedir in the passwd file to be /export/home/./username
Have a look at proftpd and wu-ftpd to - they do the job better than the

As I said in my previous response, "tput bold" will output the bold
sequence defined for your terminal in your terminfo description, or if none
is defined it will output the standout sequence.
defined for bold, reverse ("tput rev") and underline ("tput smul"), but has
standout defined the same as reverse.
Historically this makes sense: Since almost all terminals offer a reverse
video character attribute, but few in the 1970s and early 1980s offered
boldface for underline, the standout capability in termcap was set to the
sequence for reverse. As terminals allowed other attibutes and colors,
termcap and later terminfo stored separate capabilities for reverse, bold,
dim, underline, blink and italics. However standout was almost always
defined the same as reverse, since that made man pages displayed with
"more" look the same on all terminals. This is also why you are encouraged
to use only normal and standout in your curses programs -- so it will the
same regardless of the terminal.
Please note: terminfo defines separate exit codes for: standout, underline,
italics and blink; but reverse, bold and dim are all ended by the
end-standout sequence.
Your best bet is to look in the man page for terminfo(4). Each terminfo
capability is available as an argument to the tput command for use in
shell scripts.
Also note: I almost always define the following in my .profile:
BOLD=`tput bold`
REV=`tput rev`
NORMAL=`tput rmso`
UNDERLN=`tput smul`
ENDUNDER=`tput rmsl`
BELL="\a" # ksh or bash; for sh use: BELL="\07"
ESC="\033"
NL="\n" # ksh or bash; for sh use: NL="\012"
DQUOTE='"'
QUOTE="'"
export BOLD REV NORMAL UNDERLN ENDUNDER BELL ESC NL DQUOTE QUOTE
or in my .login:
setenv BOLD `tput bold`
setenv REV `tput rev`
setenv NORMAL `tput rmso`
setenv UNDERLN `tput smul`
setenv ENDUNDER `tput rmsl`
setenv BELL "\07"
setenv ESC "\033"
setenv NL "
"
setenv DQUOTE '"'
setenv QUOTE "'"
write after the TERM variable gets resolved. I can use these in my shell
scripts easily by just referencing the variables.

You can try something like this:
