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.
Prints the usage string and default locations of system files to standard output and exits.
-n, --num recs
Number of lines to print.
Start printing from last records.
Print raw records, not human-readable.
Use specified format version to display records.
Swap bytes endianness when reading records.
Use specified units of time to display data from other kernel versions and architectures.
The system wide process accounting file. See acct(5) for further details.
