A quick lesson:
r=4 - read
w=2 - write
x=1 - execute/search
3 sets - user, group, everybody(world)
Each file has a set of permissions also,
for example /sbin/arp has root:root as the user and group
with permissions rwxr-xr-x (755) meaning the user root
and anyone in the group root and the world have permission
to execute this file,
where /sbin/badblocks is root:root with rwxr-x--- (750)
meaning only root can execute the file, but the world cannot
A directory at 777 is all 3 permisions for all 3 groups
x for a directory is obviously search, you cannot execute a directory
x for a text file is execute only if it's a script (starts
with #!/usr/bin/perl or #!/usr/bin/whatever).
What you have is a perfectly normal UNIX setup and you
shouldn't change it! The permissions are set up so that you
or another user cannot screw up your system accidently.
If you need to do something as the root user, just change
to root with the command 'su', then do it and then type 'exit'
Generally there is no need to log on as root unless you are
setting up part of the system, otherwise just use it as rajiv (or
whatever your user logon is). It's really easy to mess something
up as root until you learn your way around.
It's also easier to keep track of where you keep your
stuff that you're working on if you keep it in your home directory.
Only one directory area to search.
Above all, have fun!

less page faults - less user time. the whole file ends up in ram, at

Subject: can't get hard drive to work
Date: Mon, 15 Jan 2001 05:35:59 GMT
I just bought a second hard drive (SEAGATE X15, 18GB). I installed it
into computer, no problem. It is a SCSI drive. The adaptec BIOS sees
drive during boot up. But, when the linux OS is ready to boot, it just
stops after the kernel is loaded. It doesn't even start the boot up
process.
I know that Lilo is working at some level because I can startup windows
which is stored on a 2nd partition on the bootup hard drive.
Furthermore because windows can start and read/examine the drive, I
know that the problem must be on the linux side.
The boot drive is at SCSI 0, and the new 2nd drive is at SCSI 1. there
are not SCSI ID conflicts. I have checked all that.
Can anyone provide any assistance?
Here is my lilo.conf file:

"plaympeg", a demo utility that comes with the open source "SMPEG"
library from Loki games, works _excellently!_
There are no controls for rewind/fast-forward, but you can pause
with the space key.
It uses the SDL library (www.libsdl.org). There are other players
based on SDL and SMPEG which might have nicer interfaces.

Hello. I've been upgrading a bunch. One rpm requires another, which
requires another, etc. ad infinitum. I have a KDE 2.1 system, on a RH 5.2
(but almost every package upgraded). Anyway, so many upgraded packages, now
when I try and login in the kdm login screen, the users are not there (the
little pictures of the users are gone) and when I login with root or my
usual user account, it says login failed...I can login using the console
(vertual terminal 1 I guess) so I'm sort of out of ideas. any suggestions
of where to start looking? Thanks much,

Howdy,
If you install the bash source, this line:
grep -r 'to leave the shell' /usr/src/bash-2.03/*
shows /usr/src/bash-2.03/parse.y and y.tab.c contain the phrase.
It's there in bash-1.14.7 too.
I too have noticed trouble running some programs compiled on one
system on another. I suspect it's because I have different versions
of the libs. I've even found a script that runs on Slackware 7.0 but
dies on RedHat 6.0 using bash2 both places. How do you find the two
systems?

Howdy Dirk,
This is just a guess, but your libs may be different than those the
2.4.0 kernel was compiled under before release.
Try 'grep -r smp_num_cpus /usr/include /usr/src/linux'
Maybe you only need to put a #include in kernel_stat.h.
Good luck,

The suggestion was to create a file xx_local.sh
in /etc/profile.d directory.
You would then put your PATH setting and export it
in xx_local.sh
Then you have to set the execute bit with the command
chmod +x /etc/profile.d/xx_local.sh
> Does the SECURE_LEVEL has anything to do with the xx_?
I indicated the secure_leve to show that PATH worked
for me at SECURE_LEVEL=3 and I was not running at
the "high security level" that you are using.
