FULL DISCUSSION
 

OK, but, what version of cat is that? Never seen anything like it. And how do you turn the extra stuff off?

 

Hi John,

it's bat aliased to cat :-)

And how do you turn the extra stuff off?

what do you mean?

 

I just meant if you wanted the standard behaviour of cat, because if you did cat file.txt > otherfile.txt that formatting would cause you to have a bad time, OK?

Ah ok!

No, it doesn't happen:

➜  ~ unalias cat
➜  ~ cat > filea.txt
this is a file written with standard cat
➜  ~ bat filea.txt
───────┬──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
       │ File: filea.txt
───────┼──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
   1   │ this is a file written with standard cat
───────┴──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────
➜  ~ bat filea.txt > fileb.txt
➜  ~ cat fileb.txt
this is a file written with standard cat

I'm curious to how it knows to change the output depending where the output is directed to. Like aren't both stdout from the point of view of bat?

You can detect if the output is being redirected with POSIX functions isatty(3) and fstat(2)
