Terminating a SSH session after starting background process.

This is too good. If you are planning to start a background process in the bash script in the background and continue in the script, you cannot do it until…….

mysql output to an array for easy parsing.

Today I was looking for some way to put the output of the mysql output in an array in a bash script. Quick google search yeilded to results something like this:

  <td>
    <div class="text codecolorer">
      output=$(mysql -e "select * from table")
    </div>
  </td>
</tr>

The problem with the above approach is that all the words go into separate index. So if you have a line that has space then that is split into multiple index’s. Not good…

smbtree is a very nice command to check all the machines that are present in the LAN (your connected network). For this to work you may need to look at this article also.

  <td>
    <div class="text codecolorer">
      smbtree -U <strong>username
    </div>
  </td>
</tr>
