# Calculate the total space used by specified files or directories # Copyright (c) 1992 by Hamilton Laboratories. All rights reserved. proc sizeof(files) # Method is as follows: # 1. Get a long listing of all the files of interest, walking thru any # subdirectories that may have been specified. # 2. Cut out the field 6, the column showing the space used. (Note # that the space is taken delimiter and that repeated spaces are # ignored.) # 3. Paste this series of numbers back on the command line with backquotes # and globally substitute +'s for the spaces between each pair of # numbers. # 4. Run this constructed statement back thru the parser and execute # it with the eval statement. eval return `ls -Lw! $files | cut -f6 -rd^ `:gS/ /+/ end sizeof $argv
