Trace file descriptors passed via socket
optional arguments:
-h , --help
show this help message and exit
-T , --timestamp
include timestamp on output
-p PID, --pid PID
trace this PID only
-t TID, --tid TID

only print process names containing this name
-d DURATION, --duration DURATION
total duration of trace in seconds
EXAMPLES
Trace passed file descriptors
# sofdsnoop
Include timestamps
# sofdsnoop -T
Only trace PID 181
# sofdsnoop -p 181
Only trace TID 123
# sofdsnoop -t 123
Trace for 10 seconds only
# sofdsnoop -d 10
Only print process names containing "main"
# sofdsnoop -n main
