i am using a win 8-X64 machine, with a 1.8 GHZ processor core i5, i have both the atom editor and git bash installed on this machine, is there any process by which i can start atom text editor from the Git bash shell or vice versa.
If you want to associate atom with all git operations, run:
git config --global core.editor "atom --wait"
If you just want to edit files, add an alias in git:
git config --global alias.edit "! atom"
and now you can edit any file by calling: git edit [filename]
Add atom.exe file location in Your Environmental variables.
Follow These steps:
step 1. Right click on Your atom icon where you usually open atom editor and click Properties
step 2. Copy Start in directory
it looks like this
start in: C:\Users\hemant\AppData\Local\atom\app-1.7.0
step 5. Go to Control panel and follow this directory Control Panel\System and Security\System
step 6. ON left side You will see Advanced System Settings click on it
step 7. then go to Environment Variables Tab
step 8. Inside System Variables search Path click on it, then click Edit
step 9. Add ; at the end of all directory and Paste atom directory and click
OK
step 10. Then open atom in your git bash or any console by Typing $ start atom
OR
simply Type PATH=%PATH%; C:/your atom directory in your console and Hit Enter
