Tar Is Not Extracting All Files

Hello,

I am working on a board (sbc6000x with at91sam9261 micro, linux 2.6.24 to be precise) and having some fun making script i wanted to make real application.
The board is coming with a cross compilation toolchain. When trying to make a simple "hello world" executable to print on the terminal there is no problem.
I open my terminal, give the path of the compiler, cd into the folder where my .c file is and then i type :
Code:

arm-linux-gcc -o hello hello.c

Which create my executable "hello" and this one is working. But like i said, this program only played with the terminal.

The board is starting with a script calling another executable which use the lcd display, i have the source of this executable. My idea was to look at what was in the source of this application (lots of folders and files) in order to understand how it was working. I wanted to test the toolchain on the source (with the makefile) to see if i was able to generate an executable from a application with folderS/fileS but when i try to "make" it i have this error.

In my understanding this is an object file but aside from that i don't see why it would not works.

Thank you for your future answers !

Hi

I have a folder :

Code:

/usr/local/src/myfolder

and i have there a few folders and files ...

Now i want to delete from this folder the files named:

Code:

file1.txt 
image.jpg
info.html
another.txt

and leave all the rest folders and files...

How is the correct syntax for this?

If it is possible to not use cd /usr/local/src/myfolder and then rm -r .... so i can run it from everywhere ....

Thanks

Hi,

i am trying the run a ftp daemon on my board (sbc6000x) but it seems that the ftpd service is never started by inetd.conf.

My inetd.conf is :

Code:

#<service_name>	<sock_type>	<proto>	<flags> <user> 	<server_path> 	<args> 

ftp			stream		tcp		nowait	root	/usr/bin/ftpd ftpd -w
telnet			stream		tcp		nowait	root    /usr/sbin/telnetd

Telnet don't run too but this is because i am missing some folders and i can launch it manually after creating the folders without issue, but maybe the fact that it can't run telnet because of the missing folders make it stop trying the ftp daemon ?

I check with the command "ps", the processus is not running hidden anywhere.

Hi guys,
.
For no apparent actions from me, hidden folders and files show
in my /user/home directory, they are as follows:-

folders:
.adobe .cache .config .cups .filezilla .gimp-2.8 .gnupg .gphoto .gstreamer-0.10 .icedtea .java .local .macromedia .mozilla .pki .thumbnails

Files:
.bash_history .bashrc .esd_auth .ICEauthority

In my / directory
File: ./readahead

Seeking help to verify the above folder and files are not from a harmful source or application?

If they do not post any thread to the system, how can I conceal
these folders and files, so that they don't show up any more in
my home and / directory ?

Many thanks.

Help!! In 12.04.5 Ubuntu, the /boot directory was full and had a lot of duplicate files from different dates, some I thought were unnecessary headers of updates. However, one series of files was called vmlinuz-3.2.0-29-generic. I moved all the files to /obsolete_files. I rebooted after having trouble upgrading packages (I think this is a second problem with this machine). I now get the following prompt.
grub rescue>

Is there a way to access the directory system so that I can move those files back? I really only need to retrieve one or two files off the system.

Code:

grub rescue>ls
(hd0) (hd0,msdos5) (hd0,msdos1) (fd0)

It doesn't under boot, or insmod. I can set prefixes. Am I doomed?

I'm running Xubuntu and it was a challenge just getting Copy.com on there. (I installed the desktop app on both of my computers.) Now that I have it though, I don't really know how to use it.

I know this is kind of more a Copy.com question, but I don't know anything about Copy.com (besides having it--lol) and besides, I like you LQ guys.

So yeah, I installed the desktop app for Copy.com on both of my computers. I know that if I put something in the Copy folder that will be available to both computers.

But how Copy does the backing up I don't know.

When I change a file or folder do I have to plop that into the Copy folder every time or does Copy somehow update the file or folder in the Copy folder automatically? (It doesn't seem to.)

Okay, when I, say, take the Documents folder from one computer and plop it into the Copy folder that's that. Then I take the Documents folder from the other computer and plop that into the Copy folder, then all the files from both folders will be in the Copy folder (and the Copy cloud), right?

Now I just removed a couple of files from a folder and copied and pasted the folder into the Copy folder. But then when I looked at the Copy folder the files I'd deleted were still there. What's the process? How does it work?

I mean, how does this work as a way of backing things up AND organizing things? To me it seems like a decent way of throwing stuff into the Copy folder (and cloud), but how is that different than Google Drive? I mean, that's not really a backup, is it? It's like a flash drive in the cloud.

And when I combined the same folders (with the same titles anyway, but they each had different files within them) from the two computers I'd expected each folder on each computer to have all the same files that were cumulatively on both. Instead, they're the same. And the cumulative is only on the Copy folder.

I like the notion of just throwing the folders and files into the Copy folder. It's much quicker than Google Drive. But the backing up feature eludes me and the syncing feature makes me fearful that I'll lose data or that the files will become hopelessly less organized.

Thanks.

One week user of Ubuntu v15 and I have tried to install the file Python-3.5.0a1.tar gz but without success. The following points have arisen.
1). The file was downloaded. OK
2). The file was extracted to the Desktop as Python-3.5.0a1
3). Using sudu apt-get install Python-3.5.0a1, the message 'file not found'. Why not!
4). Looking into the extracted files it seems that this is a source package and therefore cannot be installed as is?
5). Finally, using the bash command 'find' it could not find the above file either.
Can someone kindly sort this out for me.
Thanks.

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 all,

please help me with python ftplib. i was trying to copy files from my linux machine to a windows server using ftplib. everything was working good. but i'm only able to copy files from the same directory the script is. how do i copy files from a different directory? i always get "file not found error message". here's my code :

Code:

tester_name = str (socket.gethostname())
def upload(ftp, file):
    ext = os.path.splitext(file)[1]
    if ext in (".txt", ".htm", ".html"):
        ftp.storlines("STOR " + file, open(file))
    else:
        ftp.storbinary("STOR " + file, open(file, "rb"), 1024)



parse_source_path = ('/path/to/where/i/go/')
parse_source_file_list = os.listdir(parse_source_path)

ftp = ftplib.FTP("server_IP")
ftp.login("username", "pass")

folder_list = []

ftp.dir(folder_list.append)

if str(tester_name) not in str(folder_list) :
    ftp.mkd("%s"%tester_name)
    ftp.cwd("%s"%tester_name)
    for files in parse_source_file_list :
        print files
        upload(ftp, files)


else :
    print "later"

Hi Experts:

I'm new to Linux,recently i was confused with the words as below:

"To achieve sharing,the process A mmaps the executable file of process B into into the virtual address space of process A. As the Linux loader maps the executable files into the process when executing them,the two processes share the memory image of the mapped file"

questions:
1,What are the "executable files",are they ELF files?
2,How to do "mmaps"？if process A and process B share the same code segment, ,where is process A's own code segment?


Thank you in advance.
