$ procpath query --help
usage: procpath query [-h] [-f FILE_LIST] [-d DELIMITER] [-i INDENT] [query]

positional arguments:
  query                 JSONPath expression, for example this query returns
                        PIDs for process subtree including the given root's:
                        $..children[?(@.stat.pid == 2610)]..pid

optional arguments:
  -h, --help            show this help message and exit
  -f FILE_LIST, --file-list FILE_LIST
                        PID proc files to read. By default: stat,cmdline.
                        Available: stat,cmdline,io.
  -d DELIMITER, --delimiter DELIMITER
                        Join query result using given delimiter
  -i INDENT, --indent INDENT
                        Format result JSON using given indent number

$ procpath record --help
usage: procpath record [-h] [-f FILE_LIST] [-e ENVIRONMENT] [-i INTERVAL]
                       [-r RECNUM] [-v REEVALNUM] -d DATABASE_FILE
                       [query]

positional arguments:
  query                 JSONPath expression, for example this query returns a
                        node including its subtree for given PID:
                        $..children[?(@.stat.pid == 2610)]

optional arguments:
  -h, --help            show this help message and exit
  -f FILE_LIST, --file-list FILE_LIST
                        PID proc files to read. By default: stat,cmdline.
                        Available: stat,cmdline,io.
  -e ENVIRONMENT, --environment ENVIRONMENT
                        Commands to evaluate in the shell and template the
                        query, like VAR=date
  -i INTERVAL, --interval INTERVAL
                        Interval in second between each recording, 10 by
                        default.
  -r RECNUM, --recnum RECNUM
                        Number of recordings to take at --interval seconds
                        apart. If not specified, recordings will be taken
                        indefinitely.
  -v REEVALNUM, --reevalnum REEVALNUM
                        Number of recordings after which environment must be
                        re-evaluate. It's useful when you expect it to change

  -d DATABASE_FILE, --database-file DATABASE_FILE
                        Path to the recording database file
