xargs

[Nicholas Clark]

$ echo | xargs uname

vs

$ echo | xargs uname
Linux

I'm not sure whether to hate the open group:

    The utility will be executed one or more times until the end-of-file is
    reached.

( http://opengroup.org/onlinepubs/007908799/xcu/xargs.html )

for having lame behaviour and no flag to give me the useful 'zero or more'

Or FreeBSD for lulling me into an assumption that its xargs is standards
conformant:

STANDARDS
     The xargs utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compli-
     ant.  The -J, -o, -P and -R options are non-standard FreeBSD extensions
     which may not be available on other operating systems.
