I am attempting to install RetroPie as an app on Raspbian Stretch and I am done except for creating a desktop shortcut for it. The problem is that the only way to open RetroPie seems to be running a command in the command line. I can’t do it in terminal because it gives me an error saying that it can’t initialize the window. Is there a way to run a command line command as a shortcut or am I going to have to find another way of doing this?
P.S. Here is the tutorial that I followed to install RetroPie:
https://www.makeuseof.com/tag/install-retropie-app-raspberry-pi/
Probably your shell (on the raspberry) is GNU bash. So read the manual of GNU bash.
You probably want (once) to edit some Bash startup file (such as ~/.bashrc) to define functions and aliases there, and you could add executable shell scripts somewhere in your $PATH. I recommend having a $HOME/bin/ directory containing your scripts and executables, and have $HOME/bin/ early in your $PATH.
I can’t do it in terminal because it gives me an error saying that it can’t initialize the window.
Perhaps you need some display server (such as Xorg or Wayland) running (with a desktop environment or a window manager). You could run Xorg on your PC (on which you could install Linux) and connect to the raspberry using ssh -X then remote applications running on your Raspberry are displayed on your PC. IF your Raspberry is directly connected to a screen (via HDMI) you might run some Xorg server on it.
Is there a way to run a command line command as a shortcut
Yes, by making a shell alias or shell function or shell script. You need to understand how they work and change or create some appropriate file using some source code editor (I recommend GNU emacs, but the choice is yours and you might use any other editor such as vim, gedit, etc...): functions and aliases could be defined in your ~/.bashrc; shell scripts would usually have their own file with a shebang under your $HOME/bin/...

When I start neovide from my applications and run :checkhealth I get errors that node and other commands are not available. But when I start it from my terminal there is no error for those commands. I tried to copy and modify the neovide desktop file to start just nvim and see if there if something wrong with my my neovide installation. But also starting just nvim as application prints the same errors.
I'm using linux with plasma desktop
TL:DR; add a path variable
Depending on your configuration, nvim will need to know the environment to run some executables (like it is with node in your example). An easy solution is to add the path variable to the exec command in the according .desktop file. I remember that I had the same issue with node not being recognized in a configuration using my plasma installation. On gnome node was recognized and healthchecks were good, so I thought I didn't need the extra path. Later on I realized that I had trouble with other commands. E.g. when using fdfind to complete path commands. Again I had to search what the reason was and it also was the missing path.
To give an example, let's say you are using zsh and want to start neovide with multigrid enabled, the Exec line in your desktop file could look like:
Exec=zsh -c "source ~/.config/zsh/.zshrc && neovide --multigrid %F"
I enjoy using gitahed, and I would like to add a shortcut to lauch it, with github desktop I use github-desktop, but I can do the same with GA?
How can I launch gitahed from terminal?
GitAhead has a Terminal panel at Tools->Options. It has a button to install command line tools. It really just creates a symlink to the GitAhead binary in /usr/local/bin. If that doesn't work for some reason, you can create the symlink yourself or an alias. See command line options by running with the --help flag. There are only a few at the moment.
I haven't been able to find a similar question, but I can't imagine this is an issue that comes up too much.
At my workplace I've decided to switch over to a full Linux experience by using Cygwin, over what I was previously using, Git Bash.
The only slight drawback is that we have a script written in Ruby that deploys changes to our site. I can run this from my Git Bash terminal no problem, but not Cygwin as there doesn't seem to be a Ruby installation on here. I've learned about sending standard output to other terminal windows, but I've only been successful when both terminals have been the same shell.
What I'd like to do is the following:
1. Type a command into Cygwin that opens a Git Bash terminal and automatically runs ./deploy.sh on that Git Bash terminal upon opening.
2. If possible, also pass in an argument in the same command, that the script expects upon running. (In this case it's whether we want to deploy to our staging or production server).
Is this possible? So far I can get what looks to be a Git Bash terminal to open and prompt me for the server, but when I enter it, it does not work. I get an error with regards to a command within the script not being found. Thing is, running this same ./deploy.sh script in a Git Bash terminal that I open myself works perfectly as it always has. The Git Bash terminal that is being opened by Cygwin does not appear to have all of the capabilities of a Git Bash terminal I open 'the normal way'.
The command I am running so far from Cygwin is as follows:
/cygdrive/c/'Program Files'/Git/git-bash.exe "./deploy.sh"
I understand there is probably a way of getting this to work by installing Ruby via Cygwin but I'd like to mess around with my work environment as little as possible in case I somehow affect my ability to deploy my work... and besides, Git Bash definitely runs this script without an issue so I can't see why I would need a duplicate installation.
Many thanks!
I was watching a speedy workflow tutorial about Atom text editor, and saw how the guy uses Linu commands like ls (to check the files in the directory), touch (to create files eg. style.css) and mkdir (to create folders). Now in my Atom editor I am able to open the command line using the following command.
CTRL + SHIFT + T
Now in my command line the default windows command line opens up, I am able to create folder using mkdir, but the commands touch and ls don't work, which makes me wonder weather Atom has its own command line?
See the SCREENSHOT to see how this guy is creating folders, files and using the ls command.
So my question is, how do I create files in Atom? How do I get the touch command to work?
It looks like the tutorial is using the Term2 package for opening a shell within the editor (http://code.tutsplus.com/courses/speedy-workflows-with-atom/lessons/term2). Since you seem to be able to open a terminal using the described screenshot, you seem to have the Term2 package installed - so far so good.
This package opens a standard command window within the editor. The tutorial seems to be using Linux or Mac OS X as the operating system. If you're running Windows, you will only have the Windows CMD interpreter available.
Windows does not natively support the touch command (but it has a mkdir command). There is a unxtools project that provides some of the common Gnu tools. If you install that, you should be able to run touch from the Windows command shell as well. More details can be found here.
I am following this https://confluence.atlassian.com/display/BITBUCKET/Set+up+SSH+for+Git and I am stack on step 5, I want to open git bash in a linux server using putty. How will I do that? In windows, there is gitbash cmd desktop app. But in linux how will you get from normal command line to git bash?
Note: I am using putty to access the linux server. If there is other way also, please recommend me.
“Git bash” under Windows simulates a Linux environment (it uses MinGW behind the scenes, afaik).
Under a Linux distribution, you just have to have a version of Git installed. With a Debian based distribution you would for example run sudo apt-get install git (or git-core for older releases) on the command line.
Once installed, you can use it from the command line without further ado.
Actually Windows gitbash is an emulation of a bash command interpreter designed for UNIX systems. On many Linux distributives bash is a default command shell. So, when you're connecting to a Linux via putty, you're actually entering a bash shell. There's nothing more you need. You can use it the similar way as you're using windows gitbash. In a nutshell, just omit the first item in the spet 5 of your tutorial: you probably already in the bash shell.
To check out which shell you're using, run this command: ps -p $$. It will output something like this:
PID TTY TIME CMD
10967 ttys000 0:01.68 -bash
The CMD field is the shell name you're using.
