Can someone explain why this: find . -depth -print0 | cpio --null -pmd /tmp/test will copy all files in and below the current directory -and- this: find . -depth -print | grep -v .iso$ | wc -l will count all the non-iso files -and- this: find . -depth -print | grep .iso$ | wc -l will count *only* the iso files -but- this: find . -depth -print0 | grep -v .iso$ | cpio --null -pmd /tmp/test doesn't copy *anything*? Any suggestions for a work-around would also be most welcome.

Because -print0 generates a NULL separated list - so grep will match .iso\0 in the string generated by find and hence not output any list for cpio to read ...

One workaround:

find . -depth -print | grep -v .iso$ | cpio -pmd /tmp/test
