Delete .svn folders recursively using command line

Khalil Majdalawi — Mon, 05 Oct 2009 08:42:27 +0000

some times i work on small projects with friends and we use Subversion to track and store code changes, collaborate, and share project files so once we finish we usually upload it somewhere by copying the whole project folder so i face that subversion makes folder inside each folder in the project called “.svn” and that take time to remove manually and unnecessary size to upload
so i run a command inside the project folder to remove that folders recursively before upload.

Run this:

find . -name .svn -exec rm -rf {} \;

Mount ISO File

First you need to make the directory to put the ISO file into using the following command

sudo mkdir /media/isodir

Then use following command

sudo mount your_image_file.iso /media/isodir/ -t iso9660 -o loop

Now you should have your iso file mounted, and accessible from your desktop.

Unmount ISO File

Just use following command

sudo umount /media/isodir

Lazy SSH login

Khalil Majdalawi — Thu, 19 Feb 2009 09:03:54 +0000

In my work i use SSH a lot , and some times i find myself so lazy to enter password every time or write the whole command , so here is a time savior technique

as we know ssh don’t accept password to be written it something called “interactive keyboard password authentication” so we need some help , install sshpass

$ sudo aptitude install sshpass

Using sshpass you could send password to ssh example(“sshpass -p YOURPASS ssh USER@HOST“)

note: this is not secure at all so don’t use it for online servers.

Now all what we need is to put it as command-line aliases or shortcut , to do that add these lines to bashrc file

alias Myssh=’sshpass -p YOURPASS ssh USER@HOST’

note: to access bashrc file $ nano ~/.bashrc

and now all what you have to do just write Myssh in terminal and you are in
