8.81. gzip

Updated gzip packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The gzip packages provide the GNU gzip data compression program.

Bug Fixes

BZ#949820
Previously, the "-h" option of the zgrep command was absent from the source code of the gzip utility. As a consequence, the output of running the "zgrep -h" command was not parsed, and the file name was printed. With this update, the possibility to use the short "-h" option besides the "--no-filename" option has been added. As a result, running the zgrep command with the "-h" option now prints the correct lines and suppresses the prefixing of the file names on output when multiple files are searched.
BZ#961810
Prior to this update, the time stamp of an archive was set by the futimesat() or utime() system calls when using the gzip utility. Consequently, the archived file had a lower time stamp than expected because only microsecond resolution was enabled, and a nanosecond time stamp was not provided. The underlying source code has been modified to attempt to use the utimensat() or futimens() system calls for nanosecond resolution. As a result, the archived file has exactly the same time stamp as the original file.
Users of gzip are advised to upgrade to these updated packages, which fix these bugs.
