tracetree
Run a process, ptrace'ing it and all of its children, and print the entire process tree at the end.
Currently only Linux support is implemented.
Examples
Print a process tree in text format to stdout:
$ tracetree /bin/bash -c '/bin/sleep 1; /bin/sleep 1'
16665 bash -c /bin/sleep 1; /bin/sleep 1 [2.004s]
16666 sleep 1 [1.001s]
16667 sleep 1 [1.000s]
Print a process tree in JSON format to output.json:
$ tracetree -f json -o output.json /bin/bash -c '/bin/sleep 1; /bin/sleep 1'
$ python -mjson.tool output.json
