Ignore a disposable generated file.
Git: Ignore a disposable generated file inside the disposable repository created by the input setup.
printf '*.tmp\n' > .gitignore
printf 'scratch\n' > scratch.tmp
git check-ignore scratch.tmpExpected output EXAMPLE
scratch.tmp
Details
Requires Git and Bash. Run in a disposable practice repository. The test setup below creates the starting files and commits.
Use a disposable practice directory. The setup configures a synthetic author locally for this repository only; it does not change global Git settings.
Tested on Ubuntu 24.04.5 LTS · · git version 2.43.0 · bash 5.2.21-2ubuntu4; coreutils 9.4-3ubuntu6.3
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.

- x86_64 / 6.18.54.1-microsoft-standard-WSL2
- Snippet identity / locale
