Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

I have a folder called


now xyz has many sub directories  like abc , def
now abc has directories like lms, pqr etc

xyz is currently owned by me. problem is others cannot see xyz and its all subdirectories for possible issues on the server settings.
now i want to give ownership to xyz directory to ADMIN user say  crm and password say p@ssword so that all the team mates who has ADMIN crm  access can view and modify any directories and files within xyz no matter how deep they are.
how to give access to this one?

Experts - I’d like to create a Linux/Unix read-only-root role for Auditors, InfoSec and Tech Ops, so they can examine a system without risk of breaking anything.
-      Using sudo or Centrify, we can grant the privileges to run some commands as root, e.g.  ls, cat, cksum and tail –f
-      I don’t want to allow root privileges for e.g. find, view or more/less, as they can be used to modify a system

Creating the role is easy; Making it easy to use is harder
-      `sudo cat filename |less` would work fine – the `cat` is run as root, the `less` as the unprivileged user. I can create a little script utility called something like “Auditors_less” to remove the need to remember the syntax.
-      `dzdo cat filename > ~/my_copy_of_filename` would work for the same reason, and give them a local copy to work with. Call it “Auditors_cp” or just “Acp”
(`dzdo` is the Centrify equivalent to sudo)

Replacing the functionality of `find` is the part I can’t figure out. The output of `find` gives the full path to a file. `find` also allows you to select on ownership, permissions etc., but that part could be replaced by
`dzdo ls -l |grep {pattern}`

So a scriptlet that takes a starting directory as input and produces output in the form
/path/to/file      : ls –l output of file
would be great, as grep can filter the output, e.g. for globally writeable files/directories

I’ve found similar questions on formatting `ls -lR` output on, but no usable answers – general opinion seems to be…

 I am trying to delete a file on my   " Windows 7 home premium Version 6.1 Build 7601 : Service Pack 1 " laptop. This file is an Windows ISO file that was being used as 2012 R2 OS DVD for VM I had build months ago on VMware workstation.

I have removed the VMs that is using the file . After that I have used  rmdir, deltree rmdir /S etc commands. I reboot the system and stops all VMware related processes and i rebooted again. Yet, I am still getting the following error message in the attachment. I Have also tried both from cdm and powershell with elevated privilege where the command available.

I think I need to delete a registry entry or better how can I forced to delete the file from system regardless the process that using it or anything in general related to the file preventing it from deletion  !

any ideas  ?

Please look at the attachment !

We tried to get google analytics included in a joomla website.  Had it in there from before, so just tried via plugin to insert a new google id code.  Broke website.  I tried commenting out the line- didn't work.  I tried defining the variable in configuration.php - didn't work.  Restored site from backup, but that didn't fix it.  This is for a small non-profit website.  We also recently upgraded joomla versions.

We all know in VIOs we login through padmin account, when we login through that account and fire alias command I am getting an entry as alias r='fc -e -', but when I looked into the .profile file under /home/padmin I am not able to locate it's entry.

The same goes with /etc/profile, /etc/environment.

Could any one tell me where the entry made for all the alias entries other than the ones defined under /home/padmin/.profile?

Hi Guys,

I need assistance please.

I previously asked a question about locking .sh_history file.
Got help and its locked now.

But now I have a new issue.
I got assigned an RBAC role (FSAdmin). When I am not in that role i can not access the .sh_history file at all, cant even view it, which is what i want, but as soon as I switch to the RBAC role that was assigned to me, I can access the file and modify it.

How do i fix this issue.
Would appreciate your help on this.
Thanks in advance.

Hi Guys,

i was recently tasked with a task, I need to find out how to lock the .sh_history file on AIX so that users cant delete or modify the file.

The thing is we want to implement RBAC and assign roles to users but we also need to track what the users do while using that role and we need them to not be able to modify the history file.

I would really appreciate any feedback and tips.

Thank you in advance.
