IF you have made a backup of these files, you can restore them from this backup.
There is no undelete in hp-ux.

Hi,

Unix does not have recycle bin like windows. Only way is to restore from the backup.

Hi,
Once you delete any file from the system its DELETES forever from your system .If you want that file back then you have to restore from your previous backup.

Hello Nishamohan

the only option is to restore the files from backup .....

if you have networker install then try recover command and you can also use nwrecover for GUI of networker.

as noted....recover files from backup (you've got one, right?).

recovery steps depend on backup software / database in use, and how the backup was taken.

Shalom,

Out of the box, only CDE the X windows graphical interface has a trash can.

Unix and Linux have no built in recycling bin like Windows. This uses a lot of disk capacity, and creates overhead.

Without regular backups you have no recourse or recovery path.

"Hopes you have taken the backup of system.

well...thats correct *IF* he used fbackup. So far, there is nothing to indicate he's got one or what was used to perform it

actually there is no software programm like in Windows but it must be a way to recover a file on hard disk due to its nature.Check this out I did not try but maybe it is useful:

"but it must be a way to recover a file on hard disk due to its nature.Check this out I did not try but maybe it is useful:...":

use grep on an entire partition and vi the results? hardly.

and since unix will happily use available space on the drive, it can very well overwrite portions where the file used to be, which may blow the "must be a way...due to nature.." right out of the water.

it's been a couple of days since he requested this "ASAP", so either it isn't that urgent or maybe there weren't backups and the boss found out

This will be just a waste of time ... all of this depends on the disk layout (volume manager yes/no; file system type ...) also.
It may work on a linux PC if you pull the plug immediately, but not here.

Keep in mind: if your are root - think about EVERY key stroke!

Come on.

Game Over. No backup, no recovery.

I agree SEP - 16 times "backup" in this thread, should be hint enough ...

Good luck!

on a UNIX box the free blocks get overwritten almost immediately. In extremely rare cases, it is possible to recover the file (or parts of it) if you immediately unmount the filesystem and use tools like fsdb but your changes are extremely small.

Look at the following thread which provides an example by RAC
