Exclude generated files from an archive.
Linux Commands: Place exclude options before the input paths to control archive membership.
tar --exclude='*.log' -cf saved.tar source
tar -tf saved.tar | LC_ALL=C sortExpected output EXAMPLE
source/ source/keep.txt
Details
Run in Bash on GNU/Linux in a scratch directory. Tested with the GNU utilities supplied by Ubuntu. Place exclude options before the input paths to control archive membership.
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.
