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.
