If I just want to look at the file, is there a better way than cat foo.txt? I guess I can't just do < foo.txt

[–] mote@lemmy.ca 22 points 1 week ago

So close! you have to do cat < foo.txt :-) (/s)

Admittedly I still use cat for this.

This also works too, but it's more verbose:

echo "$(<foo.txt)"

It's mentioned in the Bash man pages:

The command substitution $(cat file) can be replaced by the equivalent but faster $(< file).

EDIT: I was just informed that simply <foo.txt works too.

how in the world is this not a useless use of echo and equivalent to <foo.txt

[–] dan@upvote.au 6 points 1 week ago (1 children)

OK, TIL you can just do <foo.txt. I didn't think that worked. Thanks!

i don't think you can but idk why that's by I'm asking

You can use less. There are also specialized ones for that purpose like bat.

If it's really long, I use less , because it breaks it up into navigable pages instead of filling your entire buffer. :)

Never knew about just using < though! Cool!
