Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) `git grep --no-index 123 /dev/stdin` outside of git repository What did you expect to happen? (Expected behavior) Ability to grep input from stdin What happened instead? (Actual behavior) `git grep` crashed with SIGABRT $ git grep --no-index 123 /dev/stdin BUG: environment.c:215: git environment hasn't been setup Aborted (core dumped) What's different between what you expected and what actually happened? Crash, no grep result Anything else you want to add: Plain grep can do that, so I suppose `git grep` could also: $ echo -e "123\n456\n789" | grep 456 /dev/stdin 456 Please review the rest of the bug report below.
