FAQs / difference between ext2 and ext3
« Last post by gouravjoshi on May 10, 2015, 02:56:49 AM »
Hi All,

After facing an embracing situation on Linux Basics, I though I should start reading more. I just started googling some topics, which I read when I was doing certification. Below is the difference between ext2 and ext3 file system that we use regularly and sometimes we do not recall features of them.


                  Feature                                     EXT2                                                                                                     EXT3
                 Journling                        There is no journling                                                                                It Has journling
Speed of file system(read-write)          It is bit fast                                                                                        It is bit slower then ext2 file-system
           Data corruption                   File system may be corrupted due to unplanned reboots                        Prevents file-system corruption
       Way to recover data               Require fsck to recover data after unplanned reboot                               Does not require(automatic file recovery is
                                                                                                                                                                       done at booting time)
     Online file system growth.        By default there is no Online file system growth.                                     Online file system growth
        Commands to format             mkfs.ext2 or mke2fs                                                                                 mkfs.ext3 or mke2fs -j
Max file size(if block size is 1kB)    2GB                                                                                                           16GB
          De-fragmentation                Easy and done with e2defrag                                                                   There is no data security when doing
        Data accommodation             More data can be accommodated in a give space                                     Less data is written when compare to ext2
                                                                                                                                                                        in a give space due to journling.

Hi Guys

Apologies for not being in contact with you all. I could not even look after the website for a long time in recent past. Now, I have revamp the site and upgraded the base application in it. There should not be any issue now, but in case if you find any please help me with informing that to me. I will try to rectify that as soon as possible.

I hope I will get my all friends back here. I will be waiting for the posts from you all.

Thanks & Regards,
Linux Questions Administrator

While working on script I found a good way to get a whole line from a file as set of variables. Many time we have a line and we need to get its contents as variables. For example -

We have a line "This is my file"

Now I can have it as
LINE="This is my file"

 set - ${LINE// / }

$1 = This
$2 = is
$3 = my
$4 = file

or say I have an IP Address


set - ${IP//./ }

$1 = 192
$2 = 168
$3 = 0
$4 = 1

Hope this will be helpful for many of us.
