Ubuntu Directories

I have tried installing a Ubuntu OS onto a partition (sda3).
When I had difficulties with the install, I decided to delete everything from the partition.

But now when I boot the computer, I get taken to the 'grub rescue' prompt.
I have tried to find grub in my other partitions (sda1 and sda2).
However, the command 'ls (hd0,msdos1)/' for example, does not show a grub directory.
It must've transferred grub to sda3 somehow and now I've deleted it.

I have debian live USB and am trying to install grub with:
Code:

apt-get install-grub /dev/sda

But I get the error message:
Code:

bash: grub-install: command not found

So now I don't know what's going on. Can anyone please help?

hi

hope this is the right place for noob questions

i'm struggling with this example:

Code:

$ find . -name temp -prune -o -print
from theunixschool.com

it means:
Find all the files except the ones under the temp directory.

shouldn't it be:
Code:

$ find . -path temp -prune -o -print

thx!

I have a shell script to find folders which are 25 days older and delete it, and put the deleted folder details into log file like this

Code:

 find /ahome/xxx/$FOLDER -type d -mtime +25  -exec ls -ld {} \;  -exec rm -rf {} \;  >> mylogfile.log

after running this command it deletes the folder and logs the folder deleted. But also print error msg
Code:

find: /ahome/prksh/dir/test: No such file or directory

How to suppress the error msg

https://code.google.com/p/wavelet1d/...ar.gz&can=2&q=

The above link is where I downloaded *.cpp(s) and the libraries.

If you "untar" the package, in "examples" directory, there are some demonstration files. What I wanted to do was to make an executable file out of "wavedemo1.cpp".

I modified the code in "wavedemo1.cpp"; Code:

#include "wavelet2d.h"

to Code:

#include "wavelet2s.h"

, then placed the header file "wavelet2s.h" (from /wavelib/src/linuxstatic) and the modified "wavedemo1.cpp" into my working directory.

Inside the working directory, I ran the following command

Code:

gcc -L/home/mario/wavelet/wavelib/linuxstatic -lwavelet2s wavedemo1.cpp -o wavedemo1

Then I get the following error messages.

/usr/bin/ld: skipping incompatible /home/mario/wavelet/wavelib/linuxstatic/libwavelet2s.a when searching for -lwavelet2s
/usr/bin/ld: cannot find -lwavelet2s
collect2: error: ld returned 1 exit status

I'm not sure what went wrong with my approach. This is my first time trying to use libraries on linux and it's giving me really tough times.

I would appreciate your help, please let me know if you need more details to explain things.

Thanks.

Hi

When i run this command manually on Centos 6.6 it works:

Code:

/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

but as a cron job it doesn't as i can see a folder with files there from Mar 28:

Code:

55 5 * * * /usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf

And here are the logs from cron that it is executing this at the correct time :

Code:

Mar 30 05:55:01 server CROND[9526]: (root) CMD (/usr/bin/find /backup/ -type d -mtime +1 -print0 | xargs -0 rm -rf)

Any ideas why?

Thanks

I have CentOS 7 64 bit. I have installed open-vm-tools on it.
I have installed vmplayer using
Code:

./VMware-Player-6.0.1-1379776.x86_64.bundle

Now when I try to open vmplayer on it, it does not load 'Virtual Network Device'
and shows error in terminal
Code:

Failed to build vmnet.  Failed to execute the build command.

When I check status of vmware, it shows
Code:

Module vmnet not loaded

If I try to run
Code:

vmware-modconfig --console --install-all

It gives me following error.
Code:

make: Leaving directory `/tmp/modconfig-2NfFeS/vmnet-only'
Unable to install all modules.

I am not able to open VMplayer, please help me to open it.

Thanks

--Kind Regards
Sam

System Info:

I have normal user in CentOS 7 whose name is "mostafa" (the name of the account).

I naturally have another user called root with all privileges. User "mostafa" is put into sudoers file, too.

The OS is installed in VmWare, so the system is all mine.

Problem:

Now I create a file with touch file.sh and put a command in it, but when I want to run it with Code:

sudo ./file.sh

, an error is shown that the command Code:

./file.sh

does not exist. But if I Code:

 sudo chmod 777 ./file.sh

then it gets run. My question is that, why should I use Code:

chmod 777

when I myself have created the file, and I am in sudoers.

Can anyone explain me why shuold I still use Code:

sudo chmod 777

when the creator of the file is me.

hello, I changed ubuntu 11 to ubuntu 14.10.

At the time of installation, I chose only open ssh for installation and I installed successfully.
now, I have not apache2, because when I typed
Code:

 sudo apt-get install apache2

I see:
Code:

Unable to locate package apache2

It is clear I have not apache2.now,I want to connect in internet and install it.

thanks.

I am on a x86_64 platform in Ubuntu 14. However, I would like to build for a 32-bit linux platform. I run into the following issue when I try to build using make:

Code:

/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.9/../../../libsndfile.so when searching for -lsndfile
/usr/bin/ld: skipping incompatible /usr/local/lib/libsndfile.so when searching for -lsndfile
/usr/bin/ld: skipping incompatible /usr/local/lib/libsndfile.a when searching for -lsndfile
/usr/bin/ld: skipping incompatible /usr/lib/libsndfile.so when searching for -lsndfile
/usr/bin/ld: cannot find -lsndfile

It seems like I am getting this error because I don't have the 32-bit libraries. I could not find anywhere online where I could directly procure the 32-bit version of the library. I tried to follow the steps he
http://www.linuxfromscratch.org/blfs...ibsndfile.html

but instead specifying the build for the configure command:
Code:

./configure --build=i686-pc-linux-gnu --disable-static && make

But that didn't help either.

Has anyone encountered this issue before? Any pointers on what I could try? Would I have to create a subdirectory like /usr/lib32/ and move libraries around, perhaps?

I would be grateful for any tips you could provide me. Thanks!

I am trying to convert a PDF document from an Excel and PowerPoint document. I installed it and ran the command. It gives no warning.. Just doesn't create a new PDF document. I've successfully done this before, but I think it was a different server. I've checked file permissions, but don't think it is the issue (I've tried as a normal user and as root).

I could convert doc, docx, and txt files, but not xls, xlsx, ppt, and pptx files.

Thoughts why? Is there a verbose option or a log file which I could check for clues?

Thank you
