BYTEYEARS(1) BYTEYEARS(1)
NAME
byteyears - time-space product for file residency
SYNOPSIS
byteyears [ -a ] [ file ] . . .
DESCRIPTION
Byteyears reports the product of the age of each file in
years and the length in bytes. Files for which this number
is large may be reasonable candidates for deletion. If the
file is a directory, byteyears reports (recursively) on
everything in that directory. If no arguments are given,
the current directory is assumed. If the -a option is
given, the time since last access is used instead of the
time since last modification.
Each line of output contains the number of byte years
(rounded to the nearest integer), the size of the file in
bytes, the time last modified, and the name of the file.
EXAMPLE
byteyears | sort -r | sed 10q
List the ten leading candidates in the current direc-
tory.
