How to manage Trash can or Recycle bin in Linux Desktop graphic environment

In every modern linux distros (OpenSuSE, Ubuntu, Mandriva, …) we use the graphic environment (GUI) almost all day.

Linux GUIs as Gnome, KDE or Enlightment, have a trash can where your erased files go when you delete them from a Desktop utility.

Now if you want to get rid of that from your console, you have to know that the trash can is only another folder in the file system structure, as you can figure out, and it is located at:

user@pc:~$ $HOME/.Trash

so you can send any file to Trash just moving them to there, as an example, lets suppose you have a file in your home directory called readme.txt and want to move it to the trash can (recycle bin if you prefer)

user@pc:~$ mv $HOME/readme.txt $HOME/.Trash/

Whenever you may want to restore it, just move the same file to the original location or to any other you like, just like the following:

user@pc:~$ mv $HOME/.Trash/readme.txt $HOME/

and you are done.

If you want to clean your trash can/recycle bin, just type this line

user@pc:~$ rm -rf $HOME/.Trash/*

and press enter in your keyboard.

That’s all!

How to use a swap file to increase temporarily your swap memory

Sometimes, it can be very useful to increase the available swap memory using a file, so we could have a memory boost in a snap without prepare a dedicated swap partition.
Let’s do it!

The following line would create a swapfile of 4 gigabytes using a blocksize of a megabyte (1048576).
user@pc:~$ dd if=/dev/zero of=/swapfile bs=4194304 count=1000

Then make the file as a swapfile
user@pc:~$ mkswp /swapfile

Now we have to activate the swapfile…
user@pc:~$ swapon /swapfile

…and verify that the same has been activated.
user@pc:~$ swapon -s

That’s all!
