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 reason‐
able 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 modi‐
fied, and the name of the file.
EXAMPLE
byteyears | sort -r | sed 10q
List the ten leading candidates in the current directory.
