gzip：stdin：不是gzip格式tar：孩子返回状态1 tar：错误不可恢复：现在退出

我有一个bash脚本，创build一个tar.gz并encryption然后发送到驱动器。但是，我不能打开.tar.gz后。这是我的过程

Bash脚本encryption。

#!/bin/sh # tar the automysqlbackup directory tar -zcf "red-backup-$(date '+%Y-%m-%d').tar.gz" /var/lib/automysqlbackup/ # encrypt the tar openssl aes-256-cbc -a -salt -in "red-backup-$(date '+%Y-%m-%d').tar.gz" -out "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -pass 'pass:MySecretPWD' # remove the original tar rm -rf "red-backup-$(date '+%Y-%m-%d').tar.gz" # upload to google drive gdrive upload --file "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -p "jofhriout849uioejfoiu09"

然后我下载文件并使用

 sudo openssl aes-256-cbc -e -in red-backup-2016-09-22.tar.gz.enc -out red-backup-2016-09-22.tar.gz

然后我input我的文件密码两次，现在我得到一个文件叫

 red-backup-2016-09-22.tar.gz

当我然后尝试

 sudo tar -zxvf red-backup-2016-09-22.tar.gz

并得到

 gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now

我也尝试重命名文件.tar，并尝试

 sudo tar xvf red-backup-2016-09-22.tar.gz

和

 sudo tar xvf red-backup-2016-09-22.tar tar: This does not look like a tar archive tar: Skipping to next header tar: Exiting with failure status due to previous errors

任何想法，我要出错？

这可能是因为你的gzip版本不兼容。

先检查以下几点：

哪个gzip

/ usr / bin / gzip或/ bin / gzip

它应该是/ bin / gzip或/ usr / bin / gzip。如果您的gzip指向其他gzip应用程序，请尝试从PATH env变量中删除该路径。

接下来是

gzip -V

gzip 1.3.5（2002-09-30）

您的问题可以通过这些检查点来解决。

这意味着该文件并不是一个真正的gzipped tar文件 – 或者任何类型的gzip文件 – 尽管被命名为一个。

当你使用wget下载一个文件时，检查显示Length: unspecified [text/html]指示，它显示它是纯文本（text），它打算被解释为html。检查下面的wget输出 –

这种证实你还没有收到一个gzip文件。

对于正确的文件， wget输出将显示如下所示的Length: 185515842 (177M) [application/x-gzip] ，如下所示 –

以上显示了正确的gzip应用程序文件已被下载。

你也可以通过file ， head file ， view实用程序来检查文件。例如，一个HTML文件会给出下面的输出 –

 [root@XXXXXX opt]# head jdk-8u144-linux-x64.tar.gz <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link href="/css/print.css" rel="stylesheet" media="print"> <link href="/css/main.css" rel="stylesheet" media="screen"> <link href="/css/font-awesome.min.css" rel="stylesheet">

上面显示的确实是一个HTML页面，我们正试图解压/解压 – 这是行不通的。如果确实是一个正确的zip文件（本质上是二进制文件），那么head的输出会产生垃圾，
