sudo ./adb reboot bootloader
error: device unauthorized. Please check the confirmation dialog on your device.

I'm getting the above error while trying to connect my Yureka! to my ubuntu 14.04 LTS Here's a list of what I've tried already and it still doesn't work:-

1. used USB2.0 instead of 3.0

2. added the rule in /etc/udev/rules.d/51-android.rules for my phone

3. adb retstart (kill+start again)

4. Tried deleting the adbkey, but no pop-up comes on my phone's screen while connecting again

5. tried using as a camera instead of MTP

Although, I'm able to transfer files from my phone to laptop and vice-versa, but still unable to connect through adb. I'm trying to flash factory image (LINUX) for my newly bought Yureka as per the steps mentioned here but stuck as I'm unable to unloack the bootlocker

Output of adb devices

Now in that i want those sub-sections which contains 'header=7075'

Can somebody please suggest that how do i get the complete sub-section in the result

I opened a file in vi, but unfortunately while changing it the terminal crashed. Now when I Try to open the same file again in a new session it displays the following message

E325: ATTENTION

      NEWER than swap file!

(1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.

(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r searchRefineVertTabs.jsp"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".searchRefineVertTabs.jsp.swp"
    to avoid this message.

I want to know how can i delete this .swp file. I couldn't find it on the path filepath/...../outpdir1`

I was making some changes to a remote file in vi using the terminal when I accidently pressed Ctrl+S instead of :wq.

Now everything got hanged. I tried Escape,:q! and all sorts of vi commans but nothing is responding. The Terminal Screen is stuck. I can't close the Terminal session as of now as it will lead to loss of all the changes. Please suggest what should be done

I have many servers like sdeuu1, sdeuu2, sdeuu3,.. etc.

I want to run a query on each one of them and the query is :

grep -i 'SponsoredLinksIFrame.jsp' /home/nextag/httpd_logs/access_log.1360* | 
  grep -ic 'nextag.co.uk'

this query is returning perfect results when ran on separate servers.

Now i have one server named sdalp1 through which i can ssh to sdeuu1, 2, 3 etc.. and go to that server to run the query. Now instead of doing that i want to run the query from sdalp1 for all the sdeuu servers in one go and i tried the following command and a few other versions of it:

for i in sdeuu1 sdeuu2 sdeuu3 sdeuu4 sdeuu5      \
         sdeuu6 sdeuu7 sdeuu8 sdeuu9 sdeuu10     \
         sdeuu11 sdeuu12 sdeuu13 sdeuu14 sdeuu15 \
         sdeuu16 sdeuu17 sdeuu18; do

  echo $i
done

-bash: grep -i 'SponsoredLinksIFrame.jsp' /home/nextag/httpd_logs/access_log.1360* | grep -ic 'nextag.co.uk': No such file or directory
