CompTIA Linux+ XK0-006 (V8) Practice Question

The zip utility can meet all of the stated conditions with the right combination of options:

• -r recurses into sub-directories.
• -y (or --symlinks) stores symbolic links as links instead of the files they reference.
• -s 2m splits the archive into 2-megabyte volumes.
• -x '*.bak' excludes every file whose name ends with .bak.

Putting these together in the proper order relative to the zipfile name and file list gives:

zip -r -y -s 2m training.zip /opt/training -x '*.bak'

Why the other choices are wrong:

• zip -r -s 2m training.zip /opt/training -x '*.bak' leaves out -y, so symbolic links are archived as full files.
• zip -r -y training.zip /opt/training -x '*.bak' omits -s 2m, so no splitting occurs.
• zip -r -y -s 2m training.zip /opt/training '*.bak' lists the pattern without the -x flag, so it actually includes .bak files instead of excluding them.
