Hi autoguys,
I am piping the output of a script to the shell, and using
COMMAND | sh
would not respect the -e/-x settings of the outer shell. I have thought
of two replacements:
{ set +o; COMMAND; } | sh
COMMAND | . /dev/fd/0
The second looks nicer, but it's not portable. Actually I am not sure
about the portability of the first, either.
It's my own little script, so I can use non-portable stuff, but still
I'm curious about a portable way to do this. Ideas?
Paolo
