After unsuccessful attempt to make a tar.gz
file I can't untar the file. It seems like I have lost it and yet this looks like trivial error one should be able to recover from. Is the content of the file really lost? I have tried all sorts of tar
and unzip
combinations without success.
OS environment and tar version:
$cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
$tar --version |grep tar
tar (GNU tar) 1.26
Steps to reproduce:
[weshop@demo test]$ ls
file.txt
[filip@demo test]$ cat file.txt
hello
[filip@demo test]$ tar cvzf file.txt file.tar.gz
tar: file.tar.gz: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
[filip@demo test]$ cat file.txt

On the line
you have asked to create a compressed archive of the file
file.tar.gz
, and that the archive should be calledfile.txt
. You have simply swapped the two filenames around.The file
file.txt
will be overwritten by an empty compressedtar
archive. This is why the subsequent commands displays weird things.Yes, the original contents of
file.txt
is now lost. Sorry. Restore from backup.See also this question.
