            "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",
