Install updates regularly. Don’t install software from unofficial sources. If you see a recommendation like run curl something | sudo bash, ignore it. And, in general, don’t run anything as root unless you understand what you are doing and why this cannot be done without root privileges.

Most of what you enumerated is not a terminal emulator job. There is tmux for multiplexing, search and persistent sessions, for instance. And if you want image rendering, what a hell you use TUI for this? GUI programs can also be controlled with keyboard.

What do you want to accelerate? And for what you need more than 256 colors?

Are you serious? It’s just a window where text is printed. Use what your DE provides. Now I’m mostly on LXQt, so I use QTerminal. With tiling WMs I prefer urxvt because I don’t need builtin window splitting ans tabs. I can’t imagine what other features may I need.

Or, alternatively, [[:digit:]], and dont’ forget to add a quntifier + to match multiple digits. See documentaion for details.

awk '/^\/dev\/loop[[:digit:]]+/{print}'

No, we already have a package manager.

ls /usr/share/zoneinfo/Asia | nl

Type 68.

IDK what did you mean by “their own thing”. Even if they created something similar to dkms, it is unlikely that it would conflict with dkms. But anyway it is better to find more information from official source.

popos has their own thing that will conflict with dkms

So you obviously need to manually configure that own thing to build the driver instead of relying on the installer.

The most interesting command for the Linux shell is known as Barmin patch.

su -c 'dpkg-reconfigure tzdata'

There is a repo for noble, I’ve checked this before writing my answer. It is always possible to edit apt sources config manually and specify any repo you want regardless your distro codename. IDK what is Mint Store, isn’t it about flatpacks that TS doesn’t want to use?

What do you mean by “won’t install”? If you install it with apt from repo, apt doesn’t check the distro codename, it just checks if the package dependencies are satisfied.

Well, first I need to note that blkdiscard is not more secure. But it is much more faster. It does not actually wipe flash memory, it just tells the controller to mark it as unused. So it will drop stored data at the moment it decides the best. Maybe immediately, maybe just before writing new data. But anyway it wont provide ability to read it. It would be still possible if you can get direct access to the flash memory bypassing the controller.

Second, you forgot that SSDs are not HDDs and data are not stored exactly at offset you write them. The controller remaps memory blocks as needed. And it has more blocks than actually available to user. So when you use dd (or cp, or any other program writing directly to block device) you only override blocks that are actually mapped, but some blocks can still keep old data. So using dd is also not secure in case someone can get direct access to the flash memory. But it takes much longer time and reduces the flash lifetime.

Several people here mentioned a secure erase feature of SSDs. I didn’t know about it. It should be more secure than both methods if implemented correctly by the manufacturer (i. e. clears all memory cells immediately). In the worst case it could be the same as blkdiscard, I guess.

/dev/random, seriously? This will take ages and have no advantages over /dev/zero. Even when you really need to fill your drive with random data, use /dev/urandom, there’s a chance that this will finish in couple days at least. And no, there’s no guarantee that it will wipe all blocks because there are reserved blocks that only device firmware can access and rotate. Some data on rotated blocks still can be accessible for forensic analysis if you care about this.

Just use blkdiscard.

I’m currently running mint cinnamon (how original, I know), and asking because i can’t seem to add mullvad-vpn stable repo.

What’s the problem? Mint is based on Ubuntu, use the corresponding Ubuntu repo (noble in case of Mint 22.1).

You can then combine this with s (substitute):

sed '/myregex/ s/from/to/ p'

This is not combining commands. In your example p is a modifier to the s/// command.

Just disable printing out with the -n option and add the p modifier to the s/// command to print out lines where substitution has occured. sed -n 's/your-regexp/replacement/p'
