Create an archive from an explicit file list.
Linux Commands: Use tar -T for a controlled list of relative archive members.
tar -cf selected.tar -T include.txt
tar -tf selected.tarExpected output EXAMPLE
a.txt b.txt
Details
Run in Bash on GNU/Linux in a scratch directory. Tested with the GNU utilities supplied by Ubuntu. Use tar -T for a controlled list of relative archive members.
Use a trusted list; for arbitrary filenames use null-delimited input and --null.
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; gzip 1.12-1ubuntu3.2; tar 1.35+dfsg-3ubuntu0.4
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.
touch a.txt b.txt c.txt; printf 'a.txt\nb.txt\n' > include.txt
Observed standard output
