Question

I am new to git and tried to push my project directory to github.

Below are the step I followed.

git init

git add .

git commit -m 'first commit'

git push <my repo address>

Then below error throws.

many refernced to create .gitignore file to ignore files. so created the .gitignore file with below content

*.iso
*.bin
*.ova

Then executed below commands

git add .

git commit -m 'ignoring certian image files'

git push

But again the same error has thrown.

How to fix this issue?

Answer 1

if you write gitignore that just contain :

*.iso
*.bin
*.ova

the git just ignore file *.iso *.bin and *.ova on your root directory, but not on your images/ directory,

you can try :

images/*.iso
images/*.bin
images/.ova

Answer 2

Here is a possible fix:

git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch images/*.bin images/*.ova images/*.iso'

as described here
