Each time a process is created it gets its own unique number to refer to it by. That's a Process ID, or "PID" for short.

How is it possible under UNIX to restrain the number of digits of the PID number?
For instance, we have a product that generates a PID of 7 digits, and we would like to have only 6 digits maximum instead for the PID.
Thank you for your help. (1 Reply)

execsnoop
execsnoop(1m) USER COMMANDS execsnoop(1m)
NAME
execsnoop - snoop new process execution. Uses DTrace.
SYNOPSIS
execsnoop [-a|-A|-ejhsvZ] [-c command]
DESCRIPTION
execsnoop prints details of new processes as they are executed. Details such as UID, PID and argument listing are printed out.
This program is very useful to examine short lived processes that would not normally appear in a prstat or "ps -ef" listing. Sometimes
applications will run hundreds of short lived processes in their normal startup cycle, a behaviour that is easily monitored with execsnoop.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS
-a print all data
-A dump all data, space delimited
-e safe output, parseable. This prevents the ARGS field containing "
"s, to assist postprocessing.
-j print project ID
-s print start time, us
-v print start time, string
-Z print zonename
-c command
command name to snoop
EXAMPLES
Default output, print processes as they are executed,
# execsnoop
Print human readable timestamps,
# execsnoop -v
Print zonename,
# execsnoop -Z
Snoop this command only,
# execsnoop -c ls
FIELDS
UID User ID
PID Process ID
PPID Parent Process ID
COMM command name for the process
ARGS argument listing for the process
ZONE zonename
PROJ project ID
TIME timestamp for the exec event, us
STRTIME
timestamp for the exec event, string
DOCUMENTATION
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
bose descriptions explaining the output.
EXIT
execsnoop will run forever until Ctrl-C is hit.
