- Previously, the '-h' option of the xzgrep command was not included. As a consequence, the matching lines in the output were prefixed with the corresponding file names. This update adds the '-h' option, and running the 'xzgrep -h' command now suppresses the file name on output as expected.
- Prior to this update, running the 'xzgrep -l' command did not work correctly because the source code did not handle the '-q' option appropriately. As a consequence, an error message was displayed. A patch has been applied to handle the 'grep -q' command in the source code correctly. As a result, running the 'xzgrep -l' suppresses normal output and prints file names with a matching line as expected.
- The xzfgrep command is supposed to act as an alias for the 'xzgrep -F' command. Previously, this alias behavior was not set correctly, and the patterns were processed as regular expressions and not as fixed strings. As a consequence, running the xzfgrep command produced no output. With this update, xzfgrep command works as an alias of the 'xzgrep -F' command, and running the xzfgrep command returns correct output.
- Previously, the xzgrep command returned exit status 1 when contents of one or more files did not match the requested pattern. With this update, xzgrep returns exit status 0 if there is at least one match of the pattern, which makes the xzgrep behavior consistent with the default grep command behavior.
