i want to delete all the .old files in a directory and its subdirectories. the subdirectories are about 4 deep. i've tried rm -rf *.old but i think this only goes one deep? i could use a php or perl script but it seems to me that the unlink() function is extremely slow. any ideas?

I think rm ha a "recursive search" switch, but I may be wrong. personally, I would do something like this : rm -f < find / -name *.old [s] where [s] is the proper find switch for recursive search. make sure find returns full pathes. Then pass the files list to rm -f as for unlink(), it's not as slow as you think. It should be mapped to the fastest OS dependent function. In your case, the destruction of the inode, or a "rm" using PHP, you're right, a recursive function with readdir() would do, or a de-recursified version with a maximum depth, say 5 in your case. All not that difficult. Come back again in case of errors or details needed.
