Description of problem: When growisofs is given a long list of full pathnames (using -graft-points), it fails with errmsg: /usr/bin/growisofs: Argument list too long while mkisofs is perfectly happy with the same list. Version-Release number of selected component (if applicable): dvd+rw-tools-5.21.4.10.8-2 How reproducible: Always fails. Steps to Reproduce: 1. Generate a list of filenames for an incremental backup like this: 0 /.autofsck 0 /boot/grub/grub.conf 0 /boot/initrd-2.6.10-1.741_FC3.img 0 /etc/.fstab.hal.1 ... 2. Run script: growisofs -Z /dev/dvd -dvd-compat -R -J -D -graft-points \ -allow-leading-dots -joliet-long -l \ -allow-multidot -max-iso9660-filenames -relaxed-filenames \ `awk -F '\t' '{ print $2 "=" $2 }' $1` 3. Note that awk removes the leading digit field and creates lines: /.autofsck=/.autofsck ... Actual results: If the list is long enough (> 5000 lines) growisofs barfs. Expected results: growisofs should be written to accept arbitrarily long file lists Additional info: This alternative script works fine: grep -v " " $1 | \ awk -F '\t' '{ print $2 "=" $2 }' - | \ /usr/bin/mkisofs -quiet \ -R -D -allow-leading-dots -graft-points -allow-multidot \ -max-iso9660-filenames -relaxed-filenames -path-list - | /usr/bin/cdrecord -dao -v driveropts=burnfree fs=16m -eject \ dev=$CDDEV tsize=${SIZE}s - 2> /dev/null Ie, mkisofs happily accepts the same very long list of pathnames. (Note, however, that neither will accept filenames that contain blanks, but that's separate problem.) The growisofs man page implies that extra args are merely passed to mkisofs.
Use this parameter and make a file with the filenames -path-list file A file containing a list of pathspec directories and filenames to be added to the ISO9660 filesystem. This list of pathspecs are processed after any that appear on the command line. If the argument is -, then the list is read from the standard input.
Harald: You're absolutely right. Thanks for pointing out the right answer. I should have realized that giving a long list as arguments encounters the shell limit, and has nothing to do with growisofs. Note that I did it right in my cdrecord example. My brain's on vacation, I guess.
