I have a bash script that creates a tar.gz and encrypts then sends to drive. However I cannot open the .tar.gz afterwards. Here is my process...
Bash Script that encrypts.
#!/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"
then I download the file and use
sudo openssl aes-256-cbc -e -in red-backup-2016-09-22.tar.gz.enc -out red-backup-2016-09-22.tar.gz
I then enter the passphrase for my file twice and I now get a file called
red-backup-2016-09-22.tar.gz
When I then try
sudo tar -zxvf red-backup-2016-09-22.tar.gz
and get
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
I have also tried renaming the file .tar and also trying
sudo tar xvf red-backup-2016-09-22.tar.gz
and
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
Any ideas where I am going wrong?
Just click first on that link and go to HTML page where actual downloads or mirrors are.
Its really misleading to have full link which ends in .tgz when it actually leads to HTML page where real download links are. I had this problem downloading Apache Spark and wget-ing it into Ubuntu.
https://spark.apache.org/downloads.html
Initially, check the type of compression with the below command:
file <file_name>
If the output is a Posix compressed file, use the below command to uncompress:
tar xvf <file_name>
First check the type of compression using the file
command:
file name_name.tgz
O/P- If output is " XZ compressed data"
Then use tar xf <archive name>
to unzip the file, e.g.
tar xf archive.tar.xz
tar xf archive.tar.gz
tar xf archive.tar
tar xf archive.tgz
sudo tar -xvzf ./PhpStorm-2018.3.4.tar.gz
Add "-O file.tgz" or "-O file.tar.gz" at the end wget command and extract "file.tgz" or "file.tar.gz"
Here is the sample code for google colab-
!wget -q --trust-server-names https://downloads.apache.org/spark/spark-3.0.0/spark-3.0.0-bin-hadoop2.7.tgz -O file.tgz
print("Download completed successfully !!!")
!tar zxvf file.tgz
Note- Please ensure that http path for tgz is valid and file is not corrupted
cd /Whatever/Directory/Path/The/File/Is/In
chmod +x xampp-linux-x64-7.0.6-0-installer.run
sudo ./xampp-linux-x64-7.0.6-0-installer.run
It works

This means the file isn't really a gzipped tar file -- or any kind of gzipped file -- in spite of being named like one.
When you download a file with wget
, check for indications like Length: unspecified [text/html]
which shows it is plain text (text) and that it is intended to be interpreted as html. Check the wget
output below -
[root@XXXXX opt]# 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"

This sort of confirms that you haven't received a gzip file.
For a correct file, the wget
output will show something like Length: 185515842 (177M) [application/x-gzip]
as shown in the below output -
[root@txcdtl01ss270n opt]# 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"

The above shows a correct gzip
application file has been downloaded.
You can also file
, head
, less
, view
utilities to check the file. For example a HTML file would give below output -
[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">
The above shows it is indeed an HTML page which we are trying to unzip/untar - something that won't work. If it was indeed a correct zip file (binary in nature) the output of head
would have produced garbage - something like below -
[root@XXXX opt]# head jdk-8u144-linux-x64.tar.gz

Try downloading from the official site and check if their download links have changed. Also check your proxy settings and make sure you have the right proxies enabled to download/wget
it from the correct source.
Hope this helps.
Sometimes the .gz
extension is wrongfully appended to the filename.
file foo.csv.gz
to know the actual file type.foo.csv
or whatever the actual file type is.I had the same issue. It was damaged the archive file...
