tar解压问题gzip: stdin: not in gzip format

如下所示，使用tar -zxvf解压文件时遇到”gzip: stdin: not in gzip format“等错误：

[root@DB-Server tmp]# 

[root@DB-Server tmp]# tar -zxvf Percona-XtraBackup-2.2.12-r8726828-el5-x86_64-bundle.tar 

gzip: stdin: not in gzip format

tar: Child returned status 1

tar: Error exit delayed from previous errors

最终发现这个压缩包没有用gzip格式压缩，所以不用加z参数，汗颜！

[root@DB-Server tmp]# tar -xvf Percona-XtraBackup-2.2.12-r8726828-el5-x86_64-bundle.tar
