NeoFetch

Written in Bash, Neofetch displays information about your system next
to an ASCII operating system logo (or any picture you configure it to
display).
Designed to handle show and tell, apps like neofetch are
a mainstay of desktop screenshots. They can distill information about
the operating system, kernel version, and desktop environment, but also
what theme or icons are being used, which window manager, and even which
version of Bash!
Basically, its the sort of tool made for Linux nerds like us!
One of Neaofetch’s “pluses” over similar CLI system info tools is the extent to which you can customise it. Neofetch
is highly customizable through the use of command line flags or the
user config file. There are over 50 config options to play around with.
Neofetch is now my favourite CLI system information tool.

Trash-CLI
Command Line Interface

trash-cli trashes files recording the original path, deletion date, and permissions. It uses the same trashcan used by KDE, GNOME, and XFCE, but you can invoke it from the command line (and scripts).
It provides these commands:
- trash-put trash files and directories.
- trash-empty empty the trashcan(s).
- trash-list list trashed files.
- trash-restore restore a trashed file.
- trash-rm remove individual files from the trashcan.
Usage
Trash a file:
$ trash-put foo
List trashed files:
$ trash-list 2008-06-01 10:30:48 /home/andrea/bar 2008-06-02 21:50:41 /home/andrea/bar 2008-06-23 21:50:49 /home/andrea/foo
Search for a file in the trashcan:
$ trash-list | grep foo 2007-08-30 12:36:00 /home/andrea/foo 2007-08-30 12:39:41 /home/andrea/foo
Restore a trashed file:
$ trash-restore 0 2007-08-30 12:36:00 /home/andrea/foo 1 2007-08-30 12:39:41 /home/andrea/bar 2 2007-08-30 12:39:41 /home/andrea/bar2 3 2007-08-30 12:39:41 /home/andrea/foo2 4 2007-08-30 12:39:41 /home/andrea/foo What file to restore [0..4]: 4 $ ls foo foo
Remove all files from the trashcan:
$ trash-empty
Remove only the files that have been deleted more than <days> ago:
$ trash-empty <days>
Example:
$ date Tue Feb 19 20:26:52 CET 2008 $ trash-list 2008-02-19 20:11:34 /home/einar/today 2008-02-18 20:11:34 /home/einar/yesterday 2008-02-10 20:11:34 /home/einar/last_week $ trash-empty 7 $ trash-list 2008-02-19 20:11:34 /home/einar/today 2008-02-18 20:11:34 /home/einar/yesterday $ trash-empty 1 $ trash-list 2008-02-19 20:11:34 /home/einar/today
Remove only files matching a pattern:
$ trash-rm \*.o
Note: you need to use quotes in order to protect the pattern from shell expansion.
FAQ
How to create a top level .Trash dir?
Steps
sudo mkdir --parent /.Trash sudo chmod a+rw /.Trash sudo chmod +t /.Trash
Can I alias rm to trash-put?
You can but you shouldn’t. In the early days I thought it was a good idea to do that but now I changed my mind.
Although the interface of trash-put seems to be compatible with rm, it has different semantics which will cause you problems. For example, while rm requires -R for deleting directories trash-put does not.
But sometimes I forget to use trash-put, really can’t I?
You could alias rm to something that will remind you to not use it:
alias rm='echo "This is not the command you are looking for."; false'
Then, if you really want to use rm, simply prepend a slash to bypass the alias:
\rm file-without-hope
Note that Bash aliases are used only in interactive shells, so using this alias should not interfere with scripts that expect to use rm.
SSH Error – ‘Host key verification failed’
So what is it and why do I need to know about it?
SSH, also known as Secure Socket Shell, is a network protocol that provides administrators with a secure way to access a remote computer. SSH also refers to the suite of utilities that implement the protocol. Secure Shell provides strong authentication and secures encrypted data communications between two computers connecting over an insecure network such as the Internet. SSH is widely used by network administrators for managing systems and applications remotely, allowing them to log in to another computer over a network, execute commands and move files from one computer to another.
The encrypted keys for each computer are stored in a file /home/User/.ssh known_hosts
You will need to turn on View Hidden Files in your file explorer to see the .ssh folder and all other system folders and files.
When you look at the known_hosts file there will be a line for each computer that looks like this:
|1|guO7PbLLb5FWIpxNZHF03ESTTKg=|r002DA8L2JUYRVykUh7jcVUHeYE= ssh-rsa AAAAB3NzaC1yc2EAAFADAQABAAABAQ....etc
The problem is that the hostname is “Hashed”. This is great from a security point of view. But not so useful in a “home network scenario”.
So we need to turn off the setting “HashKnownHosts = yes” to “HashKnownHosts =no “
This setting is located at /etc/ssh ssh_config at the bottom of the file for me anyway!
After you change this setting you will need to delete the known_hosts file. You will then have to reauthorize the connection to each of your computers, again. But this time when you look at the file, there will now be an I.P. Address at the start of each line.
[192.168.1.101]:22 ssh-rsa AAAAB3NzaC1yc2EAAFADAQABAAABAQ....etc
So next time you have an error you won’t need to delete the known_hosts file but instead just edit it and delete the one line that correlates to the computer that you’re trying to connect to.
