Emergency mode: sulogin fails after recovery from tar backup

location: linuxexchange.com - date: November 3, 2015
Using Fedora 22 with latest kernel I recent had to change my harddrive, but didn't want to reinstall everything. So I created a tar backup of my / system and my /home with a command like this tar -cvpzf backup.tar.gz -C /my/external/harddrive --one-file-system / I then changed my hardrive to the new ssd, nd reinstalled a minimal version of Fedora 22 on the computer, ran dnf update kernel to get latest kernel (the same I was using before the backup) Then went on a live disk and resotred my system with a command like this one: sudo tar -xvpzf /path/to/backup.tar.gz -C /my/externel/harddrive --numeric-owner Everything seemed fine. My files where back and all. Then when I try to boot on my new system, it goes straight to emergency mode, and when I try to login with my root credentials, I get this: Here is a screenshot: sulogin : failed to execute /bin/bash: Permission denied sulogin: failed to execute /bin/sh: Permission denied Error getting authority: Error initalizing authoti

How to extract a single file from tar to a different directory? [closed]

location: linuxexchange.com - date: February 12, 2012
I know that I can use following command to extract a single file to the current working directory (assume I have a tar file named test.tar and a file named testfile1 and testfile2 are inside it): $tar xvf test.tar testfile1 And I can use -C option to extract files to another directory: $tar xvf test.tar -C anotherDirectory/ When I incorporate the above two techniques together, I suppose that I can extract a single file to another directory. $ tar xvf test.tar testfile1 -C anotherDirectory/ But the result is I can only extract the testfile1 to the current working directory, rather than the anotherDirectory. I want to know how can I extract a single file from tar to a different directory?

Extract 1 file from tar.gz with bash

location: linuxexchange.com - date: January 1, 1970
Is it possible to programmatically pull a single file from a decently sized .tar.gz without extracting the entire tarball to disk? Essentially I need to get inside large tar.gz files over the network and extract 1 small text file. It seems somewhat over-the-top to pull and extract the tarball to disk, then pull the file out, then delete everything else. Also I'm going to be doing this recursively (e.g. package dependencies, each text file points to more tar.gz's), so the less network traffic and cpu cycles I can get away with, the better.

Remove New Line or Carriage return from Text File

location: linuxquestions.com - date: September 28, 2007
I have been running a very successful script removing URLs (grep and cut) from emails from my ebay favorites. In the last week or so the width of the emails that I have been receiving has narrowed to the extent that the URL now falls over 2 lines: Item title:=09Dragon 1/6 Scale MODERN British SA80 Rifle MDRW0020 Item URL: http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=3D130156919= 207&ssPageName=3DADME:B:SS:UK:1 Buy It Now price: =A36.99 Postage: +=A31.69 End time: 04-Oct-07 21:58 BST The current script just pulls off the 1st line and the subsequent wget errors out. I have tried awk, sed and tr in an attempt to remove the = sign and then the NL or CR. The = signs is easy but I am not having any luck joining the two lines up. I'm guessing that it is just an NL or CR. In vi or gedit it is not a problem to remove the NL or CR. Any pointers please. DIMonS

Which command can extract just number from a line or text file?

location: linuxquestions.com - date: July 9, 2013
Hi people, I'm using du command: du folder_name and that gives me the result, for example: 8 folder_name I wonder- how can I get just that 8 (that number) without the name of folder next to it? (I want to do that because I want to assign that value to a variable in a script.) Or if I write the result of command in a text file: du folder_name > some_file, how can I get that number (in this case 8)from that file?
