Looking carefully at "bin-pack" I found that there is a function
"dir_size" missing. E-mail correspondence with the author verified
this, and I got a fix for it. One modifies the script
"standard-funcs", which is sourced by various other scripts. Here is
the fix:
diff -c -r1.1 standard-funcs-sh
*** standard-funcs-sh 2005/11/09 21:05:05 1.1
--- standard-funcs-sh 2005/11/09 21:05:51
***************
*** 333,335 ****
--- 333,345 ----
}
trap cleanup EXIT ## Set trap to call cleanup on exit
+ dir_size() ## calculate total size of files in directory/ies
+ {
+ for ds_dir
+ do
+ ls -l ${ds_dir:+${ds_dir%/}/} |
+ grep -v '^d' |
+ awk 'BEGIN {OFMT = "%d" } {total += $5} END { print total }'
+ done
+ }
+
Also, read the code carefully -- it might not do what you really want.
It is destructive of the original data, "mv"ing it into newly created
directories, and splitting files that are too large to fit on a single
output disk.
Also be aware that there is some overhead in creating ISO9660 images,
so the 4700MB nominal size of a DVD will not hold 4700,000,000 bytes
of files.
