I'm currently using Cachy OS and have a few questions about it. First, how can I add text to a file while ensuring that a newline gets inserted at the end? I tried using `echo "hhhn"`, but that didn't work for me. Second, I encountered an issue with the message "pseudo-terminal will not be allocated because stdin is not a terminal" when using `sshpass` with this command: `sshpass -p password ssh user@address -p 22`. What does that mean? Lastly, I need to figure out how to copy selected text from a file directly to the clipboard using only the keyboard. I plan to SSH into another server, retrieve some text, exit, return to my server, and then paste that text without using the mouse. Any help would be greatly appreciated!

Hey! For adding text to a file with a newline, instead of using `echo`, you can use `printf`. Like this: `printf 'your text here
' >> filename`. This will do the trick!
For the SSH issue, the message you're seeing indicates that the command is expecting a terminal session, but it isn't getting one. If you're using `sshpass`, try adding the `-t` option to force a pseudo-terminal allocation: `sshpass -p password ssh -t user@address -p 22`.
As for copying text from a file directly to the clipboard, you can use `Ctrl + Shift + C` to copy in the terminal and `Ctrl + Shift + V` to paste. If you're looking for a keyboard-only solution, use `xclip` or `xsel` to interact with the clipboard.
For the text appending, you can simply use `tee` which is pretty handy! Just do `echo "text" | tee -a filename`. It’s a good way to handle appending and you’ll also automatically add a newline.
As for your SSH issue, it sounds like a standard problem when the terminal isn't recognized. Make sure to use `-t` with your command.
For copying text without a mouse, sure thing! You can use keyboard shortcuts like `Ctrl + Shift + C` and `Ctrl + Shift + V` in most Linux terminal emulators.
1. To append text to a file ensuring a newline at the end, try using `echo text >> file`. If you're fine with just new lines and not specific text, `echo` handles that pretty well. Alternatively, `printf` might be more flexible for your needs.
2. The error about pseudo-terminals can usually be addressed by adding the `-t` flag in your SSH command, as it forces terminal allocation.
3. For copying selected text to the clipboard, you can select text using `Shift + Arrow keys`, and use `Ctrl + Shift + C` to copy and `Ctrl + Shift + V` to paste.
