Heroku CLI won't start - heroku

I installed the Heroku CLI on Windows 10 but when I tried to open the heroku.cmd in the /bin directory, all I got is this black window. Any ideas on how to fix this?

One can use WMIC (Command samples here) and do something like this:
wmic process where (processid=PROCID_HERE) get parentprocessid

Why does this command work in Terminal but not in CMD?

Dopusrt.exe /acmd Go "c:/"
The above command works, last active Window goes to c:/ but the below command does not work.
Dopusrt.exe /info documents\filelist1.txt,listsel,0
The weird thing is it works just fine in Windows Terminal. Does CMD reserve commas for something? I really need to use CMD in this case, Since Auotohotkey seems to only speak to CMD.
Thank you.
CMD and Windows Terminal are not the same type of application. CMD is a shell, and WT is a terminal. See this post for more details.
You can run any shell you'd like in WT - CMD, PowerShell, whatever.
CMD.exe does not by itself reserve commas (to the best of my knowledge). And running cmd.exe in WT vs running it in conhost (the default console on Windows) shouldn't make a difference either.

why the git bash in windows shows could not fork child process? [duplicate]

I have had up to 8 git bash terminals running at the same time before.
Currently I have only 2 up.
I have not seen this error before and I am not understanding what is causing it.
Any help would be appreciated!
Picture attached:
Found a similar issue and solution in google groups
I opened a windows command prompt and ran the command
$ tasklist
It looks as though the ssh connections I had made in my git bash shells weren't being closed when those windows were closed and were hanging the available git bash shell windows.
This may be a dangerous solution but from the windows command prompt I ran
$ taskkill /F /IM ssh.exe
Everything appears to be working again after this. It may not have directly been an issue of orphan processes, but this worked for at least for me.
Additional note: you can also kill other processes, for example like:
$ taskkill /F /IM vim.exe
In my case, it was related with the use of VS code. Previously I have opened VS code using a git bash terminal and executing
code .
then closing the terminal.
The problem is solved by closing all the VS code windows opened.
When you have any editor or IDE configure to open a terminal as git bash, then when the IDE/IDE is running, the git bash will spin up bash from "C:\Windows\System32\bash.exe" and any other attempt to open bash from a separate window is likely to crash.
The best solution is to kill the IDE/Editor bash and open from a new window or continue from the IDE/Editor command.
I see the problem on windows in git bash when I kill my git bash console without using exit. I found killing ssh-agent.exe task from windows task manager to fix the problem.
I address this with a workaround:
Close the Git Bash window.
Open Task manager.
Find the 'Git for Windows' process.
Kill it.
Open Git Bash.
It should be ok now.
Open task manager and kill process with name bash, this worked for me.
This happens when you exit git bash without terminating existing process. Just try and kill those processes that you started from git bash.
I was running node process inside git bash, so I killed all node processes
Steps to kill
Open Task Manager
Goto Details Tab
Look for node.exe(you look for you processes)
Kill it each and every node process
Open Git Bash again
To make life easier (this problems happens quite often) create a file called fixbash.bat in home directory and paste this:
taskkill /F /IM ssh-agent.exe
When problem occurs just open cmd and type fixbash.bat to fix a problem.
Or
Just paste the taskkill command into your cmd if you don't want to create a script.
Restart your machine.
(The other answers did not work for me. (I didn't try reinstalling. Restarting is probably faster.))
finally figured out what was causing this.
if we use code like this (explicitly or implicitly) i.e. in .bashrc file
eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa
it spawns a new process.
if you don't exit it and just close the window, that process is still running. so each new bash opened just keeps adding new ones w/out disposing old ones.
when done with a bash window, simply hit ctrl+d or type exit to kill the agent process, and you should not run out of forks.
In my Case I need to kill Git bash in Windows.
So opened Command Prompt and ran below command
$ tasklist
It will list down all running tasks, then need to kill bash.exe task using below command
$ taskkill /F /IM bash.exe
For me (or anyone running protractor, which may spin up a standalone Selenium/WebDriver server), I needed to taskkill the specific webdriver which was running my tests.
So just a different argument:
or your chromedriver version may vary
taskkill /f /im chromedriver_2.34.exe
Note your driver may vary:
IEDriverServer*.*.*.exe vs chromedriver_*.**exe
Your driver may version may vary:chromedriver_2.34.exe vs chromedriver_2.33.exe
This problem got worse after protractor quit without closing the automated /test-driven browser, (due to a separate issue I don't yet understand.) Naturally many chromedriver tasks remain running, that's why kill them.
Seems to be an issue with the processes launched from the git bash indeed, like #mamacdon suggested in his comment on the top answer by #Scott Newson.
For me, the issue appeared if I launched a vscode from the bash with code, and if this instance of vscode launched an integrated git terminal while the original bash was still running.
Doesn't matter whether that terminal was launched at the start or later, as long as it was while the original bash was still running.
Didn't happen when the bash was closed before the integrated terminal was opened. Didn't differentiate between exit and closing bash via windows. Didn't happen with another older bash window still running.
The way to deal with it was for me to close the terminals in vscode with exit or 'Kill Terminal' (be careful not to mix that up with 'close pane'), or of course, closing vscode itself.
If you get this error try to remember what you launched from the bash and kill it. If the other answers worked for you, it's probably just that these are the things launched by your bash or launched by processes you launched from the bash and they somehow were getting a child of your original bash.
If you are using Visual Studio Code and you can't find ssh-agent.exe or can't taskkill it and after opening Git Bash you get that error, just go to your VSCode open Terminal>New Terminal and just press the trashbin icon the (Kill Terminal). e.g (1:bash) if you got multiple then just kill them all and you should be good.
I tried to kill all my git terminals in task manager solves the problem.
This works for me too.
good luck.
Open your Task manager, search "sh" procces and kill them.
Good luck
In my case, I was running jupyter-notebook from Git Bash and closed the terminal without closing the notebook. When I closed all running git bash terminals and tried to open new terminal, this gave me the error:
Error: Could not fork child process: There are no available terminals (-1).
Solution
taskkill /F /IM jupyter-notebook.exe
After that, I was able to run commands in git bash terminal.
i found that killing msys2 terminal in task manager solves the problem
On a more recent version of git for windows, the process to kill in task manager was "GitExtensions.exe". Killed that and the terminals restarted with no issues.
Please find the ssh-agent process in the Task Manager window.
After you stop or kill the ssh-agent process the error will disappear.
Open Task manager, find bash.exe process and kill it. Helped in my case.
In my case I had visual studio code running and closing it resolved the issue.
Windows 10 this worked for me:
1) open cmd as administrator
2) type:
taskkill /f /im git-bash.exe
3) If there was an Error: The process "ssh-agent.exe" not found. then:
type:
tasklist
4) Find and kill every process with words like "bash" or "git" (This may be a dangerous solution, but once you will find the process name, next time you will know.)
taskkill /f /im ***.exe
Im my case, the solution was to close Visual Studio Code -where I had console running too without noticing-
After closing it all back to normal.
Hope this helps someone.
In my case, I needed to kill sh.exe
taskkill /F /IM sh.exe
Many answers here are suggesting different processes they need to kill in order to be able to open a new Git Bash terminal. In my case there were multiple conhost.exe processes running which I had to kill before I could open another window successfully.
Perhaps more importantly, is why it happened. I think I know exactly what I did which led to this state. I noticed that when typing git log, if I then resize my Git Bash window, it would hang. (Pressing q would not exit the log and I could no longer type commands.) I ended up closing the window and opening another one. I was doing some testing of this repeatedly to see if I could figure out a solution to the freezing after resizing, and after doing this multiple times (probably around 10 times), I received the error in this question. The results of my testing are:
Opening a new Git Bash Window starts the following processes:
conhost.exe
git-bash.exe
git.exe
mintty.exe
Now, when you type git log, 4 additional processes open:
bash.exe
conhost.exe
git.exe
less.exe (this will only stay open if your log cannot fit on one screen)
When you close Git Bash, those 8 processes all normally go away. However, due to a bug, (which I think is possibly in less.exe) when you resize the window while viewing the log, Git Bash hangs. If you now close the window only 6 of the 8 processes close. Both less.exe and conhost.exe stay active. In my case, eventually enough conhost.exe processes built up and caused whatever the issue is that leads Git Bash displaying the error and not starting.
That said, I tried to repeat the issue but gave up after 20+ tries, which was more conhost processes than I had to kill when I was in the problem state. I suspect it's not a process number but something about the state of one or more processes that leads to the error. Obviously since other answers mention closing different processes, the "thing" that isn't closing properly and fighting against Git Bash can vary, depending on what tools you're using.
Note, I'm using Git version: 2.37.1.windows.1.
For windows, in task-manager kill sh.exe.
In my case the problem was the file [git_install_dir]/etc/nsswitch.conf
I previously followed the instructions given here:
https://cygwin.com/faq.html#faq.using.startup-slow.
But this caused the "Could not fork" error instead.
My wrong nsswitch.conf file was:
passwd: files
group: files
So I restored the file and problem solved. Now my [git_install_dir]/etc/nsswitch.conf is:
passwd: files db
group: files # db
db_enum: cache builtin
db_home: env windows cygwin desc
db_shell: env windows # cygwin desc
db_gecos: env # cygwin desc
Tried the following solution which worked for me:
Kill all existing git.exe
Added my credentials for BitBucket in the Windows Credential manager under the generic credentials section.
Reinstalled git, it is now working fine.
In system bash type:
ps
Kill any bad looking process:
kill -9 <ID>
Worked for me.

How to run VSCode from the command prompt

I for security reasons cannot run VSCode plainly. I have opened it in the past, but now due to specific reasons, I may only run VSCode from the command prompt. I've tried
start "path/to/file" code and start code "path/to/file"
but none work I'm on Microsoft Windows [Version 10.0.17134.407]
how may I run this by going to Windows+R then 'cmd' then start/ run?
Also it would be great if I could use this for a separate user.
I'm looking for something like:
Runas /user:user\admin /savecred "C:\Program Files (x86)\vs-code.exe"
The use of start is useless if VSCode is in the environment variables.
You can use code C:\Users\%username%\Desktop\File.c for exemple.If it doesn't work, I advise you to use a vbs script instead
You also don't need to run VSCode as an administrator unless you need to edit a file in a protected folder.
Maybe not the exact answer to the question, but...
To start Visual-Studio-Code from CMD into the current folder write:
code %cd%
The environment variable cd tell VS-Code to open it with the current folder
just open a cmd terminal and type code followed by
just open a cmd terminal and type code followed by return keyborad key.
Well shoot, as it turns out that after doing some experimentation I found out that there's a way. Do this:
Simply stick this:
runas /user:Techtiger255\admin /savecred "C:\Users\Admin\AppData\Local\Programs\Microsoft VS Code\Code.exe"
inside of a shortcut (.lnk file)
Open your command line of choice (Powershell or Cmd) and enter the exact file path of your shortcut ex:
"C:\Users\Standard\Desktop/VSCODE.lnk" and hit go, stupidly simple really, just had to find the code.exe file path.

Windows Run dialog and cmd

I have a simple problem in which I can launch a program with the Run dialog n windows, but not from the CMD (or PowerShell).
The command is steam://run/<app-id>
I would like to know how to run the same command from the console. I tried steam steam:// Steam.exe but none worked (the last one only opened steam)
In the command window, use the start command
start steam://run/<app-id>
Not really the right forum for this Q, but a quick google leads to Valve's pages that show the command-line options for steam.exe. I'd recommend a google yourself, but for completeness it looks like steam.exe accepts a -applaunch parameter.

Why is Windows 'Run:' different from CMD line?

When I type 'http://www.google.com at the Windows Run: prompt it launches my default browser.
But when I do it at the CMD or Commnad prompt it does not. I assume that there is some form of RunDLL command being issued but I can't find out what.
Does anyone have any insight?
I think it's the equivalent of using START.
If you try
START http://www.google.com
from the command line (or a batch file), it should work fine.
What Jon said appears to be correct. I tested it with mailto:someone#somewhere.com. Interestingly if you wish to make run work like the default behaviour of cmd, you can do the following:
Start -> Run -> cmd /c http://www.google.com. Not sure why anyone would ever need to do that though!
