It does indeed depend on the OS, but I think the maximum length is for 
the total command line, not for individual arguments. At any rate, for 
my linux mint system I see an ARG_MAX value of 2097152.

Note that there is also a limit to the number of arguments that can be 
passed on a commandline, and as a rule of thumb it is *probably* 
ARG_MAX/4-1, but if this is something that concerns you, you no doubt 
have other things to worry about <g>.
