Error "Not a git repository" when trying to execute git command inside of bash script

[dcurletti]

I have a bash script:

#ts-precommit.sh

SRC_PATTERN=".*\.(ts|tsx)$"
if git diff --cached --name-only | grep --quiet -E "$SRC_PATTERN"

That I am running like so:

"husky": {
    "hooks": {
      "pre-commit": "sh ./ts-precommit.sh"
    }
  }

And I get the following output:

Not a git repository
To compare two paths outside a working tree:
usage: git diff [--no-index] <path> <path>

Any reasons why I wouldn't be able to call git from the script?

Hi @dcurletti,

Hmm I don't really know why it doesn't work :/
What do you get if you echo $PWD and echo $GIT_DIR in your ts-precommit.sh?

Hi @typicode -
The working directory is correct, but the GIT_DIR was wrong.
I fixed it by doing unset $(git rev-parse --local-env-vars)
You can also append env -i to any of your git commands if you don't want to unset the vars for the entire script.
