Hello all
I do most of my work (involves a lot of C/Python) on a development server that is shared with several other people. As a result we all seem to do a bit of the system administration chores (there is no sysadmin). This tends to work alright, but installing and maintaining packages and l...
I have a couple of years of experience with ubuntu, but this is my first time with a non-ubuntu based distribution. I managed to successfully install Crunchbang from a bootable usb stick, created with unetbootin (my hom laptop's cd drive is dead) and at the end of installation, it asked me whethe...
So I'm still kind of new to linux, but what are the steps towards setting a linux box up in such a way that it can send mail using shell?
echo "hello world" | mail johnny@moo.com
I mean, I've done the necessary sudo apt-get install mailsystem (or something like that) which sets up the mail com...
How would I send /dev/stdin to both /dev/stdout and a $logfile in one command?
One solution would be just to do it once for both:
cat /dev/stdin > /dev/stdout;
cat /dev/stdin > $logfile;
But that seems bad. Is there a better way?
Hi,
I have 15 identical Linux RH 4.7 64 bit severs.
They run cluster database (cluster is application level).
On ocasion (evry month or so) random box (never the same though) freezes.
I can ping the box and ping works.
If I try to ssh in the box I get:

Installing something in windows takes a click of a button. But every time I try to install something in linux, which is not found in APT, I get so confused.
You download a zipped folder, then what? If you are lucky there is a README, refering to some documentation, which might help you, if you ...
Parsing an array using IFS with non-whites space values creates empty elements.
Even using tr -s to shrink multiple delims to a single delim isn't enough.
An example may explain the issue more clearly..
var=" abc def ghi "
echo "============== IFS=<default>"
arr=($var)
for x in ${!a...
I know what should be difference between su and su - but in my system (debian testing) for example PATH are the same
[root]# su
[root]# echo $PATH
/user_path/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
[root]# exit
[root]$ su -
[root@debian ~]# echo $PATH

I'm attempting to mount a password protected network share from a NAS unit that works by appearing as a windows share. On Windows, I just Map Network Drive, and enter in \x.x.x.x\ShareName , then enter a password at the prompt.
On my Linux system, when I attempt to open smb://x.x.x.x/ServerName,...
I'm looking for a sticky notes/knotes/etc type program with one difference: I can stick a note on a window, rather than the desk top, and it will remain attached to the window.
Basically, I want to be able to annotate windows. I want to be able to say "this xterm is the one where I'm doing proje...
I need a tutorial , preferably with pics/diagrams to get oriented to how a typical Linux distro. is organized and used (including the basic software installation work flow). It shouldn't be a 500 pages book. A concise 20-30 pages tutorial is what I am looking for , so that I read it over the wee...
When I run this script I get this error-->
./myscript.sh: 16: arithmetic expression: expecting primary: "1 ** 1"
When I run this shell script with bash, as in #! /bin/bash on the first line the math works properly, unfortunatley I need to use /bin/sh. What am I doing wrong? I'm on Linux Mint ...
Well, obviously there is a difference, but I'm curious about the rational behind why some things go under /usr/include/sys and others go under /usr/include/linux, and have the same header file name? Does this have something to do with POSIX vx non-POSIX?
Also, I've managed to populate /usr/inclu...
