rename files (in this case pdfs) numerically in date order

find . -name "*.pdf" -print0 | xargs -r0 stat -c %y\ %n | sort|awk '{print $4}'|gawk 'BEGIN{ a=1 }{ printf "mv %s %04d.pdf\n", $0, a++ }' | bash
Caution: distructive overwrite of filenames Useful for concatenating pdfs in date order using pdftk

What Others Think

Hmm... There are a few problems with this command. You've correctly used find -print0 and xargs -0 to deal with filenames with whitespace, but awk '{print $4}' will only use the first part of the name. The only way around this is to manually parse $0. If the pdfs aren't in the current directory, they will all get renamed, but they'll still be scattered. To fix this, you'd need to strip the path on the second mv argument You can simplify the awk, by using the ++var (pre-increment) notation: ... | gawk '{ printf "mv %s %04d.pdf\n", $0, ++a }' | ...
