我有一个 Bash 脚本，它创建一个 .tar.gz 文件，加密，然后将它发送到一个驱动器。但是，之后我无法打开 .tar.gz 文件。这是我的过程...
加密的 Bash 脚本。
#!/bin/sh
# Tar the automysqlbackup directory
tar -zcf "red-backup-$(date '+%Y-%m-%d').tar.gz" /var/lib/automysqlbackup/
# Encrypt the tar file
openssl aes-256-cbc -a -salt -in "red-backup-$(date '+%Y-%m-%d').tar.gz" -out "red-backup-$(date '+%Y-%m-%d').tar.gz.enc" -pass 'pass:MySecretPWD'
# Remove the original tar file
rm -rf "red-backup-$(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
然后我为我的文件输入密码两次，现在我得到一个名为
的文件red-backup-2016-09-22.tar.gz
当我再尝试
sudo tar -zxvf red-backup-2016-09-22.tar.gz
我明白了
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
我也试过重命名文件 .tar 也试过
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
我哪里错了？
最佳答案
这意味着该文件并不是真正的 gzipped tar 文件——或任何类型的 gzip 文件——尽管被命名为类似文件。
当您使用 wget 下载文件时，检查是否有像 Length: unspecified [text/html] 这样的指示，这表明它是纯文本 (text) 并且它是旨在被解释为 html。检查下面的 wget 输出 -
wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz"

这种确认您没有收到 gzip 文件。
对于正确的文件，wget 输出将显示类似 Length: 185515842 (177M) [application/x-gzip] 的内容，如下面的输出所示 -

以上显示正确的 gzip 应用程序文件已下载。
您还可以使用 file、head、less、view 实用程序来检查文件。例如，一个 HTML 文件会给出以下输出 -
head jdk-8u144-linux-x64.tar.gz
输出:
<!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">
上面显示它确实是一个 HTML 页面，我们正在尝试解压缩/解压 - 无法正常工作。如果它确实是一个正确的 zip 文件(本质上是二进制文件)，则 head 的输出会产生垃圾 - 如下所示 -
head jdk-8u144-linux-x64.tar.gz
输出:

尝试从官方网站下载并检查他们的下载链接是否已更改。还要检查您的代理设置，并确保您启用了正确的代理以从正确的来源下载/wget。
