_permanently_??!? ah, well, Ok, each to their own ....
create either of the following script (for most modern
Bourne-ish shells), and install it as `ps', only after
renaming the real `ps' as `ps.real':
export COLUMNS=1000 exec ps.real -w "$ at domain "
exec ps.real "$ at domain "
aliases and functions are not permanent, in the sense
they do not, and can not, affect all users at all times.
should (GNU?) ps(1) do this? IMHO, no (with a possible
+ line-chopping (_if_ that's what you want) is the job of
either your terminak (hardware or, e.g., xterm(1)-ish
program), or your PAGER (e.g., less(1)-ish program) ....
+ pipes and files are, by definition, a streams of bytes;
lines/records/whatevers per se don't exist ....
+ the program reading the data from a pipe either needs
to deal with arbitrary long lines (and it can chop if
it so wants), or is the job of a helper tool (e.g.,
a cut(1)-ish filter) deliberately stuck into the pipe
for that purpose ....
+(possible exception) if backwards compatibility is
an issue, that's what the (e.g.) POSIXLY_CORRECT-ish
environment variables are for; i.e., set as appropriate
to achieve your desired effect ....
if you have something you do "all the time" (read: "more
than once"), package it up as a script --- rather than
adding totally unnecessary complications which are then
(esp. w.r.t. GNU) _not_ documented"! .... arrggghhhh!!!!
