|
# USAGE: execsnoop [-a|-A|-ehsvJ] [-c command]
|
|
#
|
|
# execsnoop # default output
|
|
#
|
|
# -a # print all data
|
|
# -A # dump all data, space delimited
|
|
# -e # safe output - parseable
|
|
# -s # print start time, us
|
|
# -v # print start time, string
|
|
# -J # print jail ID
|
|
# -c command # command name to snoop
|
|
# eg,
|
|
# execsnoop -v # human readable timestamps
|
|
# execsnoop -J # print jail ID
|
|
# execsnoop -c ls # snoop ls commands only
|
|

|
|
# The parseable output ensures that the ARGS field doesn't contain
|
|
# any "\n"s, which normally sometimes can - and would wreck postprocessing.

|
|
# FIELDS:
|
|
# UID User ID
|
|
# PID Process ID
|
|
# PPID Parent Process ID
|
|
# COMM command name for the process
|
|
# ARGS argument listing for the process
