On Windows, default terminal for Atom\'s Platformio-Ide-Terminal is Powershell (at least, that is what I get without any configuration).
I would prefer a terminal using
Step by Step Solution
Put the following line as per as your Terminal Requirement
For cmd- C:\\WINDOWS\\System32\\cmd.exe
For Power Shell- C:\\WINDOWS\\Sysnative\\WndowsPowerShell\\v1.0\\powershell.exe
For bash- C:\\Program Files\\Git\\bin\\bash.exe
or C:\\Windows\\System32\\bash.exe
(depending on how you install the bash). Be Sure, that you have already install the bash into your computer.
Now, you can integrate bash, cmd, git bash, Power Shell into Atom using platformio as terminal.
For CYGWIN users, the bash executable from the following location has proved useful for setting the shell override Settings >> Packages >> Platformio Ide Terminal >> Settings >> Shell Override
C:\cygwin64\bin\bash.exe
Set the default shell in: Edit>>Settings>>Packages>>Platformio Ide Terminal>>Settings>>Shell Override
You can use the git's bash as proposed here as you probably already have git installed.
C:\Program Files\Git\bin\bash.exe
For someone who still can't get this to work because your git bash is installed in AppData. This worked for me.
C:\Users\saurabh\AppData\Local\Programs\Git\bin\bash.exe
If you are now using Ubuntu for Windows 10 (downloaded from the app store), you can change it to that as well.
Ubuntu gets installed in Windows' PATH by default, so just change the default shell to:
ubuntu.exe
That's it. Just remember that to get to your code, cd to /mnt/(driveletter)/wherever/your/files/sit.
