NAME
dump-acct - print an acct/pacct file in human-readable format SYNOPSIS
dump-acct [-r|--reverse] [-R|--raw] [-n|--num recs] [--byte-swap] [--format] [--ahz freq] [-h|--help] [files] DESCRIPTION
The dump-acct command transforms the output file from the accton format to the human-readable format: one record per line. Each record consists of severald fields which are separated by character "|" (the meaning of concreate field depends on the version of kernel package - with which the accton file was created). OPTIONS
The following options are supported: -r, --reverse Print the output in reverse order. -R, --raw The records will be printed without any parsing. -n, --num NUMRECS Display only the first NUMRECS number of records. --byteswap Swap the bytes (relative to your system's native byte order) in --raw output. --format Set output format with --raw option. --ahz FREQ Set the AHZ (platform dependent frequency in Hertz) to FREQ. -h, --help Print a help message and the default location of the process accounting file and exit.
