                Or

To change a Normal user to super user in UNIX/LINUX


  1. Create a new user  (Or select a exists user)
  2. Set id 0 in selected user attributes through /etc/passwd file like-
(Before Edit )     asharma:*:128:20::/home/asharma:/sbin/sh
(After Edit)         asharma:*:0:20::/home/asharma:/sbin/sh

How to Zip files in Linux

Suppose we have below mentioned files have to zip in a file named mohan.zip


Now you can check zip  file is there


For unzip a file run below command 


----------------------------------------------------------

For "command not found" error in HP UNIX-


PATH=$PATH:/usr/sbin:/usr/bin;export PATH

---------------------------------------------------------------------------------------

To check active user in web server-

ps -ef| grep httpd| wc -l
