I'm trying to get ZIP working in a Cocoa app of mine.
How can I find out whether I should be able to expect whether a
particular shell tool is installed, or not?
For example, I'm thinking of using "ditto", which I think looks like
a pretty safe bet that it will be on all installations of OS10.2. But
that's the thing, to me it just "looks" like it, I don't *know* it.
So where do I go to find out what tools I can expect to be installed
where?
I could expect that across different installations, installed tools
may vary. Some people may not have installed developer tools. Some
people may have opted for a minimal install without all of the BSD
subsystem (this option was there on earlier versios of OSX and maybe
still is). What tools exist may also vary across versions of MacOSX.
It might be (for all that I know), "ditto" did not exist on OSX until
10.3.
I'm not really looking for an answer on any particular shell tool
here, more just a general way so I can find out for sure for myself.
Or even to be told that there *is no* such way to find out how likely
it is that a tool is installed, that I really need to have a whole
set of different OSX installers so I can find out for myself
experimentally.
