don't worry i dont' mind
of course if you are writing scripts or programs that are to be heavily
used in a system programming context it's good to keep performance and
resource consumption in head and avoid any wasting.
but if you are in the context of time-to-time scripts then readability is
important too.
if you are alone progamming your machine, you are supposed to know what you
do, and remember what you wanted to do monthes or years later.
in a professional context, or at least when you are not alone, you are
supposed to write things that others can read, understand, and maintain
too, not depending on you, and even years later. that's why i'd give an
advise to all : unless performance is an issue, better write a readable
code even if there are more steps than necessary, than a quick code that
only a few can read (and of course please add comments !)
the problem when writing things like that (grep [n]tpd) is that unaware
people just copy the commands as-is and do not understand why it has been
written so. then they are even not able to explain to another why they
wrote that, and when updates are necessary, it all breaks down...
have a nice week end !
