[TUHS] cut, paste, join, etc.

[Will Senn]

All,

I'm tooling along during our newfangled rolling blackouts and frigid 
temperatures (in Texas!) and reading some good old unix books. I keep 
coming across the commands cut and paste and join and suchlike. I use 
cut all the time for stuff like:

ls -l | tr -s ' '| cut -f1,4,9 -d \
...
-rw-r--r-- staff main.rs

and

who | grep wsenn | cut -c 1-8,10-17
wsenn   console
wsenn   ttys000

but that's just cuz it's convenient and useful.

To my knowledge, I've never used paste or join outside of initially 
coming across them. But, they seem to 'fit' with cut. My question for 
y'all is, was there a subset of related utilities that these were part 
of that served some common purpose? On a related note, join seems like 
part of an aborted (aka never fully realized) attempt at a text based 
rdb to me...

What say you?

Will
