Software Ubuntu center is missing in Ubuntu 16.04 .

• Is there an alternative for packages management ?

OR

• It is a return back to Synaptic ?

It turns out that editing /etc/hosts is enough to add an entry of DNS.

Is there a built-in cmd , where we can:

1. add host

   cmd: $ sudo mycmd 10.103.23.34 myme.com

   Result : 10.103.23.34 myme.com

2. Add hostname

   cmd : $ sudo mycmd 10.103.23.34 omac.org

   Result : 10.103.23.34 myme.com omac.org

3. Modify IP

   cmd : $ sudo mycmd 10.103.23.18 omac.org

   Result : 10.103.23.18 myme.com omac.org

Using the convert command, we can concatenate img1.png with img2.png:

convert img1.png img2.png +append  full_img.png

However, the command above adds img2.png to the right of img1.png. How to add img2.png at bottom of img1.png using the convert command?

I search on this issue in many websites , however , if i found , i found tuto related to old versions :

In fact , Installing is done successfully :

 sudo dpkg -i splunk-6.3.1-linux-2.6-amd64.deb

However , i don't know how start it ?

I want to run a job three times per month from 3-5 pm.

Hence, I should add a line to /etc/crontab which satisfy those needs.

How do I add this line known that I try the following, and it seems not correct:

0 15-17 1,10,20 3 * /home/kia/publish.sh

How to share the internet of my iPad Air with my Ubuntu PC?

On the iPad I navigate to: Settings -> Personal Hotspot, there it displays:

TO CONNECT USING USB
1 . Plug iPad into your computer

2 . Choose iPad from the list of network services in your settings

Where can I find your settings?
Is it the settings of the iPad or the settings of Ubunutu?

Sometimes, we note that we have unused nested containers (directories) .

For example :

mkdir -p ~/grandpa/pa;

And pa directory is the only file existed on grandpa.

Hence, all files of pa should be moved to grandpa, then pa will be deleted.

My question is there is a built-in command line do such a mission:

i.e:

orphan  ~/grandpa/pa/*

or

fatherless ~/grandpa/pa/*

I want to add this key binding in the suitable conf file :

Control-t: "top -Ss \C-m"

Which means : Bind Ctrl+T keys to top -Ss command line .

i enter on terminal sudo ls ~/.inputrc to check existence of this conf file . i get this error:

 No such file or directory

Where can i put this binding. What is the target file with the new FS hierarchy of Ubuntu14.04 .

I try to display the help pages of unset command line , i get as a result the following output:

No manual entry for unset

I see this issue since they are similar , however , it cannot be solution for this issue . Indeed , that issue has been resolved by installing some packages using this cmd :

sudo apt-get install manpages-posix manpages-posix-dev

So , i try to do the same thing ;except modifying posix by unset , so i do this :

sudo apt-get install manpages-unset

The result was :

Unable to locate package manpages-unset

The explicit question is :

How to display manual of unset

I am revising for LPI exam ,and i cannot know this information which is :

the name of the file resides in /proc that is used to pass information from boot-loader to kernel ?

rpm -qpl dhad-9.0.27891-2.x86_64.rpm allows to display all file paths and directory paths of this package .

I want to filter only file paths :

i try :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm | find -type f

Also :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm|grep -f

Also :

rpm -qpl dhad-9.0.27891-2.x86_64.rpm |ls -f

All didn't work.

What is the most efficient way to get the intersection between two files , there is :

sort file1 file2 | uniq -d

I follow this issue to configure PIdgin for MS Lync 2013 .

I get this message :

Web ticket request to https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc failed

Known that settings has been configured as following:

And No proxy:

i received this certificate from MS sysadmin .

And i don't know if it is useful in Ubuntu . If so , How can i import it?

And Why rproxy appeared in message error even there is no proxy in my settings .

I mean :

https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc

UPDATE :

I found where can i import certificate :

However , i get new error message:

SSL Connection Failed

Known that Authentication Scheme is: Kerberos , not TLS-DSK

I have Ubuntu 14.04 , apache 2.4.7

$ apache2 -v
Server version: Apache/2.4.7 (Ubuntu)
Server built:   Apr  3 2014 12:20:28

I made many attempts to access from my public IP

Firstly , i enable authz_host :

$ sudo a2enmod authz_host

Then , i follow this issue to configure Apache :

Unfortunately, i don't find the file whose path : /etc/apache2/conf.d/restrict.conf

My question : What's the new config file to allow access from Public Ip.

That it means : Be able to Access :

either by: http://localhost/myProject

or by : http://87.x.x.x/myProject

I exploit internet in PC by tethering USB from Samsung Tab2 :

A java developer who want to send SMS ,may use SMSLib project.

SMSLib requires to set up :

• javacomm library (if it is windows plateform)
• rxtx library (if it is linux plateform ) by adding it in JDK library See documentation

I did many attempts to send mail using mail command as follows:

abdennour@pc: mail -v [email protected]
Subject: Hello World!
This is an email to myself.

Hope all is well.

Cc: 

I get this error message:

/usr/lib/sendmail: No such file or directory
"/home/abdennour/dead.letter" 9/261 
. . . message not sent.

i run the following command line to remove all files/dirs in directory :

       cd /home/abdennour/android/

       rm -rf *

the architecture of this directory is as following :

   /home/abdennour/android/
   /home/abdennour/android/documents/
   /home/abdennour/android/documents/medialib/
   /home/abdennour/android/documents/preview/

   /home/abdennour/android/images/mlibrary/
   /home/abdennour/android/images/mlibrary/thumbs/
   /home/abdennour/android/js/

i want to remove all with excluding the following directories :

  /home/abdennour/android/documents/
  /home/abdennour/android/images/mlibrary/

An URL link has been saved in *.url file via Windows. If you double click the file in Windows, it will open your default browser to the indicated URL. Here is an example of *.url file content:

[InternetShortcut]
URL=http://abdennour-insat.blogspot.com/

When the same file is copied on Ubuntu OS, Ubuntu handles it such as a text file. Hence, the browser does not open the URL when double-clicking the file.

My question is: what is the equivalent of *.url file in Linux to make shortcut file for URLs?

really, I do all my efforts to run an android project through eclipse on a tablet "Samsung galaxy Tab s2/ GT-P3100" under Ubuntu 12.04.

i add the vendor id of samsung in ~/.android/adb_usb.ini

   0x04e8

i add rules in /etc/udev/rules.d/51-android.rules as following :

SUBSYSTEMS=="usb", ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="6860", MODE="0666"
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="*:ff420?:*", MODE="0666"

then , i restart udev & i run the following command

sudo udevadm control --reload-rules

i updates /etc/udev/rules.d/99-android.rules

SUBSYSTEM=="usb", ATTRS{idVendor}=="04e8", SYMLINK+="android_adb", MODE="0666"

the thing that perplexed me is the listing of the tab when running the following cmd :

abdennour@estifeda1:~$ lsusb 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And the device also is well mounted:

I finally recourse a very long solution but, as usual, in vain :
