How to get the command line args passed to a running process on unix/linux systems?

Question

On SunOS there is pargs command that prints the command line arguments passed to the running process.

Is there is any similar command on other Unix env

Answer 1

If you want to get a long-as-possible (not sure what limits there are), similar to Solaris' pargs, you can use this on Linux & OSX:

ps -ww -o pid,command [-p  ... ]
