I deleted ddirectories WITHOUT first saving them with "pushd" command. Is there a way to recover files that were erased as a reult?Please post the exact SCRIPT you used and what messages, if any, were displayed. Meantime do as LITTLE as possible on the hdd concerned.

Dusty is right about using the hard drive. If the files / directories are important, I would unplug the drive completely. If you have another computer, you can run some data recovery SOFTWARE like GetDataBack by www.runtime.org. It is free to try, and once you verify it can GET your files back it will cost $60-70 (depending on if the drive is NTFS or FAT) to register the software to actually recover the data. If you don't want to pay that much there are other programs, but GetDataBack is my personal favorite.

Here are more links for data recovery:
