Interesting; why wouldn't you use `head`? Who knows how big textfile.txt is?

generally, speaking, if you don't have an idea of how big the file is, or it would take up too much real-estate on your terminal window, sure. 100%. It was just an example.

lot's of times we sort of know what we are working with, but don't remember the particulars especially

Don't forget to pipe head into 'cat -v'... that text file could contain _anything_!

Thank you for pointing this out! This is much safer.

I really recommend folks use "less" over cat, especially keyboard oriented folks. Different terminal emulators don't always have the scroll behavior I want, not do they always allow me to search the file I'm looking at. "less" does all those things, in nearly every environment no matter the terminal emulator, and has other wonderful options to boot (chop long lines so they don't wrap can be nice for logs, line numbers can be VITAL, etc).

I still uselessly use cat though, it's such a nice way to build a pipeline.

My useless cat is that I always use `cat file | less` when I could just `less file`.

I've been typing cat for over 25 years. Old habits die hard.

I hate that when I use `less`, then quit, the output goes away.

You can run "less -X" for that, but it may have other problems depending on how you use less (e.g. scrolling up, etc.)

`file` will tell you too

Won't tell you the delimiter.
