       dump-acct - print an acct file in human-readable format.


       dump-acct  [-r|--reverse]  [-R|--raw]  [--format] version] [--byteswap]
       [--ahz] hertz] [-n|--num recs] [-h|--help] [ files]


       dump-acct filename prints a list of all executed processes.  This  list
       is  written  by  the  kernel  which  must  be compiled with BSD process
       accounting enabled (Debian kernel image have it  already  enabled).  It
       must  be  started with accton(5).  Note that on Debian systems, this is
       ensured via the init script /etc/init.d/acct.

       All fields  are  separated  by  vertical  line.  Fields  are:  command,
       version,  user time, system time, effective time, uid, gid, memory, io,
       pid, ppid, time.  User,  system  and  effective  times  are  ticks  per
       second.  One tick is usually 1/50 of a second. The time field shows the
       start time of the process.

       The --raw switch, as well as the --format, --byteswap, and --ahz can be
       used as a handy format converter.


       -h, --help
              Prints the usage string and default locations of system files to
              standard output and exits.

       -n, --num recs
              Number of lines to print.

       -r, --reverse
              Start printing from last records.

       -R, --raw
              Print raw records, not human-readable.

       --format version
              Use specified format version to display records.

              Swap bytes endianness when reading records.

       --ahz  Use specified units of time to display data  from  other  kernel
              versions and architectures.
