Autzoo.309 hacknews utzoo!henry Sat Mar 28 16:56:39 1981 improved tar(1) Several improvements have been made to tar. The most prominent ones are that it now records ascii user/group names, and uses them if it finds them on the tape, and likewise records and uses ownerships and permissions for directories. Several other minor changes, see tar(1). The tape format remains compatible; this results in two anomalies when using different versions of tar to read and write: 1. A tape written with old tar will draw warnings about possibly-wrong directory permissions from new tar. The d option shuts it up. 2. A tape written with new tar, read with old tar, will give a spurious file named .TARDIRPERMS. in any directories created during the read. The file is zero-length and has the ownership and permissions that the directory SHOULD have.
