Is 'getconf ARG_MAX' the command to use to determine the max. command
line size?
Thanks for the reminder. Yes, 'getconf ARG_MAX' is the current system
limit, although getconf(1) isn't present on some systems (cygwin and
mingw come rapidly to my mind). On my Fedora 14 system, I see a 2M
limit for ARG_MAX; empirically, mingw has a much smaller limit of 32k.
