I don't think ejecting a drive should be this laborious. How i can use eject command without using sudo?

Provide the rights to execute “sudo eject” without password in sudoers, then write a script
untested.

The right to eject depends on the device.

Hello cwdztsd88 & welcome to LQ.

Disk operations customarily require root permissions for security reasons. You can use sudo if you want to do this. You can set up sudo in /etc/sudoers and do clever things, letting users have root as much or as little as you like. You can also put the dvd (I presume it's a dvd) in /etc/fstab with the 'users' or 'user' option and this might allow you to eject. Man fstab for the details. Test it and see. You might also eject using a right click in the File Manager in X.

Is your user account in the cdrom group?

What do you get back when you issue the "groups" command? Is "cdrom" in the list?

no i dont see it

I am scared of doing bad things to my computer so i dont want my user have root permission always.

Then you should add it
That's why you use SUDO, but beyond that, how do you think you're going to apply updates or do anything system related without admin rights? You can't do that on Windows or Mac either. All you need to do is:

• Take regular backups
• Use your own brain to think about what you're doing and be careful

Because eventually your system WILL die, and you'll have to restore your data; the backups are for that. And if you 'do bad things' to the point your system doesn't work, you have now learned what not to do, and can just rebuild your system.

We've all killed systems in the past, and you either have ALREADY done it, or you WILL do it. There's no third option.

In deed. Sudo is quite an ingenuous tool. Whatever you think to know about it, find out, what it really does.

Users of computers divide into three types, according to someone

1. Beginner: is afraid to do things in case he presses a key that breaks the whole computer.
2. Intermediate: Doesn't know what to do when he has pressed a key that broke his computer.
3. Expert: Someone who breaks other people's computers.

Get out of stage 1. The forum here helps And buy yourself a backup disk, make backups, and then you can just restore the backup if you break or wipe stuff.

Problem solved by adding suid to /usr/bin/eject, all i wanted was to eject flash drive to extend it's service time and since my main drive is nvme it's hard to write /dev/nvme0blablabla instead of /dev/sda. I dont think i would do a mistake. Thanks for everyone's replies, didn't expected to get attention this fast.

in that case you might want to mark it solved
