Here is way to create zip and unzip recursively. For this, You have to install zip and unzip installation packages with following commands in terminal. Open terminal by pressing Ctrl + Alt + T.

sudo apt-get install zip  // to install zip command packages. 
sudo apt-get uninstall zip // to Unistall unzip command package.

Create a zip file :

Go To the path of that folder which you have to make zip and run following command to make a zip file.

zip -r zip-file-name.zip directory-to-compress/
  • zip :  This is the application name, which we are using to create zip file.
  • -r : For recursive
  • zip-file-name.zip : Name of result zip file name.
  • directory-to-compress/ : Name of the directory which we want to compress.

You can add more than one directory in single archives by following command :

sudo zip -r zip-file-name.zip directory-1/ directory-2/

There is no need of -r (recursive) option for single file archive.

sudo zip a2bizz.zip a2bizz.php

Unzip file

Following command will help you to unzip a file.

sudo unzip a2bizz.zip -d destination_dir/
  • sudo : super user
  • unzip : This is unzip application, which is using to extract a zip file.
  • -d : Shorts for destination
  • destination_dir/: This is the directory where you want to extract files.

You can also use unzip a2bizz.zip to extract data on same dir.

Enjoy :)

 

Fix “System program problem detected” error on Ubuntu

Posted by a2bizz on in Linux, Ubuntu0 Comment

From some last previous days I notice down that there is a error popup coming while I start or restart my system, on my Ubuntu OS. The error is “System program problem detected”. Basically comes up when a certain application crashes. Ubuntu program “apport”, responsible for detecting such crashes and upon user consent, report these crashes to developers. This process intends to get the problem fixed by the developers.

However, the problem is the popup comes up each and every time when the system starts and annoyed a normal user. Really, there is no need to show popup to user when they can’t do anything or it should not come back when the report is submitted regarding the error.

So, today we are here that how to get rid of this popup –

error

 

 

 

 

 

We can remove crash reports which are resided into /var/crash directory. These crash report files cause the error message to appear every time Ubuntu boots.

$cd /var/crash
$ ls
_usr_bin_do-release-upgrade.0.crash
_usr_share_apport_apport-gtk.1001.crash
_usr_bin_update-manager.1001.crash

Just Remove the crash report files .

$sudo rm -rf /var/crash/*

After removing these crash reports, the Popup will stop appearing, but it will reappear again in future when a new crash report generated and added to the directory.

So toget rid of these, we should have to turn off ‘apport’ program which is responsible for detecting crash reports and to popup error message –

$ sudo nano /etc/default/apport

nano will open the file in below manner

#set this to 0 to disable apport, or to 1 to enable it
# you can temporarily override this with
# sudo service apport start force_start=1
enabled=1

Change value of enable=1 to 0 and save the file from the next boot the error message will disappear, if you don’t want to restart system then restart apport from command line –

$sudo restart apport
