Dear Author, I'm submitting patches that I made to the dd program and manual page. The changes allow the use of the conv=stat keyword, which will cause the program to display copy progress based upon the number of blocks read out of the total number of blocks that will be read. This is very useful when using dd to copy disk images to harddrives. The original fileutils-4.1 package was downloaded on January 20, 2003 from rpmfind.net. Please consider the inclusion of these changes for future fileutils distributions. Thank you, Eric Thomas [email protected] _______________________________________________ Bug-fileutils mailing list [email protected] http://mail.gnu.org/mailman/listinfo/bug-fileutils
