How to remove the some applications I don't use from Xubuntu?

Question

The apps that have red dots next to them, I want to uninstall, since I have synapse, kazam, xpad instead and the rest, I don't need. I tried Software Center, and synaptic and apt-get, and could not locate them.

Also how to remove xfce4-terminal? I tried apt-get, but it will remove a billion library related to xfce, is it safe to remove it that way? Because I have terminator and xterm.

I want to remove the Electronic section, because it only has Arduino IDE, which is also available in the development section, thus I don't need it.

Answer 1

Here's a script to find the package names:

programs_to_rm=('Application Finder' 'Notes' 'Onboard' 'Orage Globaltime' 'Screenshot')

results=()
for prog in "${programs_to_rm[@]}"; do
    result="$(grep -lR -m1 "^Name=$prog$" /usr/share/applications | tail -n1)"
    result="$(dpkg -S "$result" | head -n1)"
    results+=("${result%%: *}")
done

echo "${results[@]}"

Basically, this should work:

sudo apt-get remove xfce4-appfinder xfce4-notes onboard orage xfce4-screenshooter

---

To remove the Electronics section:

1. Command:

   sudo -H nano "$(grep -lRm1 'Arduino IDE' /usr/share/applications)"
   

2. Press Ctrl+W, then type Categories=Enter. Edit the line to remove Electronics;.

Answer 2

To remove them from the Menu, Alacarte, or 'Main Menu' should work.

It's best NOT to remove any software that "comes with" Xubuntu unless you have very little room on your hard drive. A few are safe to remove (like Abiword and Gnumeric if you prefer LibreOffice), but so much software is dependent on other stuff it can create new problems. It's not using anything but storage space if it's "just there."
