I am new to linux, used to use windows. I am trying to convert to linux and I really love it. I am trying Ubuntu 14.10. I have a question about how to find the installed applications easily in Linux. You know in windows, after I installed an application, I can always find it in the "all application" list. Even no, I can always try to search for its folder from the bottom. However, I am trying two DE, Unity and Gnome 3.12, and it seems that it's more difficult to do this. For example, I've just installed Anaconda3. After installation, it does not show up in the launcher nor the "all application list". I tried to search "Anaconda" or "Spyder" but hits nothing. It looks like it's also impossible to open the file manager to show all folders in the partition on which ubuntu is installed. I can open a terminal and "cd /" and then search it? But that's text interface. So my questions are: Are there any way to find an installed application easily. Is there something like the file manager in windows that can show all the folders in the linux partition or in the whole harddisk?

Consider this scenario:

$ file a b c
a: empty
b: cannot open `b' (No such file or directory)
c: cannot open `c' (No such file or directory)

$ file b/c
b/c: cannot open `b/c' (No such file or directory)

$ file a/b
a/b: cannot open `a/b' (Not a directory)

Why Not a directory instead of No such file or directory? Reason for the question: the ` a/b' (Not a directory)` may suggest that a/b needs to be a directory. However, a/b` may be a file. --- UPD. It seems that a/b may _not_ be a file because a is a file. Hence, the question: why `cannot open a/b' (Not a directory)` instead of cannot open a' (Not a directory)``?

Good evening! I'm trying to run an electron application on my PopOS 22.04 machine. It throws an error such as:

[Majsoul_Plus][ERROR] gpu-process-crashed, killed: false
[Majsoul_Plus][ERROR] gpu-process-crashed, killed: false
[19781:0624/031622.888875:FATAL:gpu_data_manager_impl_private.cc(986)] The display compositor is frequently crashing. Goodbye.
Trace/breakpoint trap (core dumped)

After some research, I figured out that I need to run it with the --no-sandbox argument which works fine. I then wanted something that I can run the application with less effort and later add it to the quick launch menu (the one that activates when pressing the windows key). So I put together this little script, in the same directory:

#!/bin/bash
./majsoul-plus --no-sandbox

Which does what its supposed to do! However, I would like to not have the hanging terminal in the background. I tried nohup ./majsoul-plus --no-sandbox & and combinations but it no longer executes. I would also like to incorporate this into a .desktop file to add it to my quick access menu. This one also refuses to execute properly, even in the simple working variant. Any ideas?

I know it's fairly easy with simple terminal commands but I still want a program where I say e.g.,:

> addtopath "~/bin"

and it does it permanently without me having to edit some config files and remember the correct syntax. Is there something out there? best would be installable with apt.

I would like to switch, in terminal, key combinations with control to combinations with win key so e.g. ctrl+c becomes win+c, ctrl+d becomes win+d. Then I would like to set ctrl+c/v for copy and paste. Is there a terminal emulator or shell configuration options that allows this?

Another name for the *keyboard viewer* is the *special characters keyboard viewer* developed first in OSX, Youtube video here . It is used to visualise the dynamics of typing different key combinations in first-level/second-level/... ways. **Warning** I do not want to have virtual keyboard like shown by the confused answers in the thread Onscreen keyboard? (like OSX's Keyboard Viewer) where the title is about *Onscreen keyboard viewer*, not virtual keyboard. I tested Florence/Onboard/xvkbd/... but the virtual keyboard is risky because it can misconfigure your keyboard settings, forcing you restart your system, so no to virtual keyboards. You can view static keyboard viewer by *Language menu* at top > *Show Keyboard Layout* > Output, or from the settings, *Region & Language* > select an input source > click on the keyboard button in the lower-right-hand corner; this will display the keyboard layout in Fig. 1. This view is static, *i.e.* it displays all accessible characters at once; it does react to key-presses, but only by highlighting the depressed key(s). It would be easier to understand the layout if it showed the characters accessible with the current set of modifiers: *e.g.* the P keycap would show only p by default, and would would change to P if you pressed Shift, ö (on a Dvorak layout) if you pressed AltGr, and Ö if you pressed ShiftAltGr. In OS X, the feature has been 5-10 years, but I have not found anything builtin in any Linux distro nor any program in apt by the following searches. apt search viewer | grep keyboard I think Gnome 3.22 can support such a tool in Linux. I need the tool to better visualise how to typo A with dots/... (ä, ö, ...) in Linux.

Background: One of my colleagues who doesn't come from a Linux background asked me about using ./ before some commands and not others, so I explained to him how PATH works and how binaries are chosen to be run. His response was that it was dumb and he just wanted to not need to type ./ before commands. Question: Is there a way to easily modify the behavior of the shell such that $PWD is always the first item on PATH?

I often "lose" my Google Chrome after using it on second monitor. After disconnecting the monitor, I cannot find a way to get Chrome back, other than restarting the system. Closing the app with keybindings, etc does not help. The system obviously thinks that the second monitor is still there. Wanted monitor: current active monitor only i.e. the laptop monitor I can reproduce the situation in X11 and Wayland. OS: Linux Debian Stretch 9.1 Window manager: Gnome 3.22 on X11 and Wayland 1.17
