You are right - multiple lines will result in multiple command line
arguments, not necessarily
multiple invocations.
Hmmm... interesting. Look at that input:
$ cat /tmp/t
me "Shlomo" "hello there,
how are you"
It's a multiline [but properly quoted] message. Let's try xargs:
$ xargs cat < /tmp/t
xargs: unmatched double quote
And now let's try my prior suggestion:
$ eval cat "`cat /tmp/t`"
cat: me: No such file or directory
cat: Shlomo: No such file or directory
cat: hello there, how are you: No such file or directory
See how cat(1) got exactly the wanted 3 arguments?
Seems like I just won the bash-judo :-)
I'm not sure who you addressed this to, but that's basically the other
side of the point I was making - back-quotes eventually flaten the lines
and allow the shell to include the entire file as a single command-line
argument, while xargs by definition will pass each input line as a
separate command line argument, regardless of quotation marks in the
input.
