KonradDos's questions

I am using subversuin to manage my project files. One thing is annoying for me. Every time I want to check out my repo I need to use "svn co "URL_TO_MY_REPOSITORY" command. The ULR is very long. I have tried to make alias of this url using alias repo='MY_URL' command. Unfortunetly it does not work.

The svn co repo command returned this error: svn: E205000: Error parsing arguments

Is there any way to make alias of URL?

What is the command to find the RAM size in computer? I want to see result in MB.

Yesterday I tried to create a bootable USB stick using

sudo dd if=[PATH TO YOUR .iso FILE] of=/dev/sd[THAT 1 LETTER]

Everything went well. Next day morning when I tried to start my system I've got error message after BIOS section. The error:

/dev/sda1 contains a file system with errors, check forced. 
Inodes that were part of a corrupted orphan linked list found.
/dev/sda1: UNEXOECTED INCONSISTENCY; RUN fsck MANUALLY.
           (i.e., without -a or -p options)
fsck exited with status code 4
The root filesysten on /dev/sda1 requires a manual fsck
BusyBOX v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs)

After fsck /dev/sda1 command I can see messages about broken Inodes. After that I can run my system, but I can't use any application installed by myself. Only terminal works. I can't even create a text file because of Destanation is read-only error. I tried to run few application in terminal. For example, after xyz$ opera I can see Buss Error (core dumped) message. I am getting this message after all commands, even sudo apt-get autoclean does not work. I don't know how to repair my system.

I have downloaded dpkg file of virtualbox 15.1.4 on my hard drive. The problem is I can not start the program. I used dpkg -i /directory command to install the file but something is going wrong and the program is crashing. I got this error in terminal:

         available for the current kernel (4.4.0-64-generic) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /sbin/vboxconfig
