Run a command safely for each matching file.
Linux Commands: Use find -exec with argument placeholders so spaces in filenames remain intact.
find files -type f -name '*.txt' -exec cat -- {} +Expected output EXAMPLE
hello
Details
Run in Bash on GNU/Linux in a scratch directory. Tested with the GNU utilities supplied by Ubuntu. Use find -exec with argument placeholders so spaces in filenames remain intact.
Tested on Ubuntu 24.04.5 LTS · · GNU bash, version 5.2.21(1)-release (x86_64-pc-linux-gnu) · bash 5.2.21-2ubuntu4; coreutils 9.4-3ubuntu6.3; findutils 4.9.0-5build1
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Unprivileged snippet process, external networking disabled, read-only root filesystem, and a fresh temporary working directory. 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.

Test input setup
These are the prepared inputs used by the test harness. See Details above for the prerequisites and how to run this example.
mkdir files; printf 'hello\n' > 'files/my note.txt'
Observed standard output
hello
Exit code: 0. Standard error: empty. Validation: Exact stdout comparison. System-dependent values above are one recorded run.
