There is sudo version 1.6.7p3 installed in our Linux machine. But when I execute "sudoedit", it shows "command not found". May I know why this is happening? What is the way to make sudoedit work?
What is your linux distribution? sudoedit should come with sudo, however, considering how old (circa. 2003) your version of sudo is I would bet that there was not support for sudoedit at this time according to the changelog.
But that should not be a problem, if you have sudo, sudoedit is just the same as sudo -e.
