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
