I've identified 4 types of input that can be passed to a command line utility: Pids, Core files, a command (executable with options), or nothing. Here is my interpretation of which command line utilities can take what types of arguments. fcatch: pids, or a command. fcore: pids. fhpd: pids, corefiles, a command or nothing. fstack: pids or cores. fstep: pids or a command. ftrace: pids or a command. Is there anything I'm forgetting, or adding?
