How to run a single command in rhel for a particular user



e.g: only ls command should execute, if we try for other commands we should get a error like permission denied



I am uisng visduo file and created a user and assigned a permission like



abhitest ALL=(ALL) /bin/ls


and I tried too abhitest ALL=/bin/ls



but its not working




sudo




share|improve this question






















  • This would allow user abhitest to run sudo -u <any other user> ls <any parameters>, i.e. the user would be able to run the ls command with any parameters as any user, including root. But it would have no effect at all for commands run as user abhitest: if you want that, you need to set up a restricted shell for that user.

I supposed you refer to sudo mecanism (visudo is part of sudo)



with 



abhitest ALL=(ALL) /bin/ls


you should be able to run, as abhitest



sudo /bin/ls


  • you will be asked root abhitest's password. (this may or may not what you intend, assuming a real command)

try ti use in sudoers 



abhitest ALL=(ALL) NOPASSWD: /bin/ls /some/secret/dir


you should be able, as abhitest to run



sudo /bin/ls /some/secret/dir


note that both



sudo ls /some/secret/dir
sudo /bin/ls /some/other/secret/dir


won't "work". In first case ls is not /bin/ls, in second case directories are different.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
