Bug ID: 205358
Summary: bsdtar(1) does not return an error status when an
input path is not in the filesystem
Product: Base System
Version: 10.2-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: [email protected]

bsdtar(1) emits a warning but does not return an error status when one of the
input files cannot be found. This is a regression vs. the bsdtar in 8.x.
To test:
tar cf /tmp/file.tar nonexistent-file-name && echo Return value broken
Returning an error is important for unattended scripts that depend on the
return value to get failure conditions -- This was discovered after a file was
missing from an automated build where the build process completed with a
warning only.
The libarchive based cpio(1) does the return an error code in this case.
The difference seems to be that cpio returns and error status for the internal
errors ARCHIVE_FAILED and ARCHIVE_FATAL, while tar only returns errors for
ARCHIVE_FATAL.
