I'm using Cachy OS and have a few questions on working with the terminal. First, I want to know how to add text to a file while ensuring a newline is inserted at the end. I tried using `echo "hhhn"`, but it didn't work. Second, I'm getting the message "pseudo-terminal will not be allocated because stdin is not a terminal" while trying to use `sshpass` with the command `sshpass -p password ssh user@address -p 22`. What does this mean? Lastly, I need a keyboard-only method to copy selected text from a file to my clipboard, as I'll be SSHing into another server to get some text, then returning to my server to paste it without using my mouse.

If you're looking for a straightforward approach, simply using `echo text >> file` will append your text to the end of the specified file with a newline. Also, if you utilize tools like `xclip` or `xsel`, you can manage clipboard operations directly from the terminal. Just keep in mind that they require X11 to function!
For copying text from the terminal without using a mouse, you can select text using `Shift` + arrow keys. Then, to copy, use `Ctrl` + `Shift` + `C` and to paste, `Ctrl` + `Shift` + `V`. It’s an easy keyboard shortcut that works like a charm!
About the SSH issue, that message typically means that `ssh` can't allocate a terminal for your session, often because the input is coming from a script or similar. You can look into the `-t` flag with `ssh` to force a pseudo-terminal allocation, though you'll have to check if that fits your use case.
For adding text to a file with a newline, you can use `tee` or `printf`. For example, `printf 'text
' >> yourfile.txt` will do the trick nicely. Just remember that `echo` doesn't handle `n` as a newline character correctly!
Thanks for the tip! I'll try adding the `-t` flag and see if that resolves the issue.
