[bug #51151] [wishlist] xargs -o support for interactive commands

[Thorsten Glaser]

Follow-up Comment #8, bug #51151 (project findutils):

Hi Bernhard and Andreas,

thanks, but I’d change a few minor things:

1. Do not remove the list of all options at the top, it really helps one to
get a quick overview and the specific spelling if one only vaguely remembers
the correct option but gets it upon seeing it.

2. ↓

+The \-o option is an extension to the POSIX standard for better
+compatibility with BSD.

I’d change that into:

+compatibility with BSD. See below for an example of how to achieve this
portably.

3. In Andreas’ patch, obviously, do not remove the </dev/tty example but
reword it slightly.

Rationale for #2 and #3: while the BSD extension is added, documenting this is
likely still good for when one searches the documentation for information on
how to achieve the same effect with either older GNU xargs or non-BSD/GNU
xargs (modulo the problems I stated e.g. wrt. ‘--’).
