            "content": "dump-acct filename prints a list of all executed processes. This list is written by the  ker‐\nnel  which  must be compiled with BSD process accounting enabled (Debian kernel image have it\nalready enabled). It must be started with accton(5).  Note that on Debian  systems,  this  is\nensured via the init script /etc/init.d/acct.\n\nAll  fields  are  separated by vertical line. Fields are: command, version, user time, system\ntime, effective time, uid, gid, memory, io, pid, ppid,  time.   User,  system  and  effective\ntimes  are  ticks  per second. One tick is usually 1/50 of a second. The time field shows the\nstart time of the process.\n\nThe --raw switch, as well as the --format, --byteswap, and --ahz can be used as a handy  for‐\nmat converter.\n\n",
