Ref. to How to install using USB Using Windows Starting with CentOS 6.5, one can create a bootable USB key simply by installing the ISO file on the key using a program such as  Win32 Disk Imager . This will delete all information already on the key. Downoad: Win32 Disk Imager Install Win32 Disk Imager Transfer the ISO image to USB using above Win32 Disk Imager. Click on "Write" button. Ready to boot and install from your USB key.

You need to use the option  -f : $ grep -f A B The option  -F  does a fixed string search where as  -f  is for specifying a file of patterns. You may want both if the file only contains fixed strings and not regexps. $ grep -Ff A B You may also want the  -w  option for matching whole words only: $ grep -wFf A B Read  man grep  for a description of all the possible arguments and what they do. NOTE: A= file. Searching in file B to see if ANY of the words in file A occur in it.

while read line; do grep -q $line A.txt || echo $line; done < B.txt >C.txt I have got the above example, its very interesting and helpful as well.  If A  is the file with the first content and B  is the file with the second content.  It prints what is not found in the second file. Can save output using redirection operator.

Git In software development , Git / ɡ ɪ t / is a distributed version control and source code management (SCM) system with an emphasis on speed. [ 3 ] Initially designed and developed by Linus Torvalds for Linux kernel development, Git has since been adopted by many other projects. Every Git working directory is a full-fledged repository with complete history and full version tracking capabilities, not dependent on network access or a central server. Git is free software distributed under the terms of the GNU General Public License version 2.

This is explained below :- Im having Vmware 9 with CentOS 6.4 Up-Running. Im adding the hard disk :-   Next> Create a new virtual disk SCSI maximum disk size (GB): 1GB // you can select as per your requirement Additional HDD added:-   select >>OK  Open clone session on SSH : select tail -f /var/log/messages   Keep scanning the host . And, get detected in fdisk as well in /dev/* directory:  echo "- - -" > /sys/class/scsi_host/host0/scan echo "- - -" > /sys/class/scsi_host/host1/scan echo "- - -" > /sys/class/scsi_host/host2/scan As in my case i had host0,host1,host2   When the HDD is detected, in host2:- Remove the Added partition, using the following command:- i.e., # echo 1 > /sys/block/devName/device/delete Example,in our case is "/dev/sdb # echo 1 > /sys/block/sdb/device/delete
