/*
* NAME
* countprogs.d - count processes invoked by a specific user
*
* SYNOPSIS
* sudo dtrace -s countprogs.d <uid>
*
* DESCRIPTION
* List and count every processes that is started by the user, while
* this script runs. The user id is passed in as an argument to the
* script.
*
* NOTES
* - The script needs to be terminated with ctrl-C. In case the
* script is running in the background, get it to run in the
* foreground first by using the fg command and then use ctrl-C
* to terminate the process. Otherwise, typing in ctrl-C will do.
*
* - To ensure a process is started while the script is running,
* either execute this script in the background, and type in one
* or more commands, or run it in the foreground and type in the
* command(s) in a separate terminal window on the same system.
*
* - The results of an aggregation are automatically printed when
* the tracing terminates.
*/
/*
* Fires on every process that starts execution. An aggregation called
* proc_name uses the executable name as a key and counts the number of
* times this executable, or process, is started.
