We can consider "pipes" abstraction to be fundumental. Decades of usage
prove a pipeline of processes usefulness e.g.,
tr -cs A-Za-z '\n' |
tr A-Z a-z |
sort |
uniq -c |
sort -rn |
sed ${1}q
See http://www.leancrew.com/all-this/2011/12/more-shell-less-egg/
Whether or not a pipe is connected to a tty is a small
detail. stdin/stdout is about pipes, not consoles.
