Hi, Today I made some mistake, I mount the remote server my home directory into local laptop. when I tried to umount it, I justed type the rm -r remote_mount_dir after I realize it, seems some directoy under ~/home has removed, one is .ssh, obviously. others I couldn't tell, like: -bash-3.2$ firefox Error: no display specified -bash-3.2$ xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set what's the sequence of rm-ing do? I mean, based on which order it removes file. are there some history records those romove process. Thanks, Best regards,
What the F! are you doing using rm -r to umount it with rm -r?The correct sequence of actions if you want to mount point to be deleted after you're done with it is:
umount ~/<mount_point> rmdir <mount_point>NEVER use rm -r unless you are sure you have files in a directory that you want to remove. rmdir is safer for removing directories. Since you shouldn't have files in a mount point (although nothing stops you from doing so - you just can't see them when the folder is used as a mount point), rmdir is always appropriate.
If I understand your e-mail correctly, you mounted your home directory for your account on a remote machine to ~/home on your laptop. If you rm -r'd that directory, you have lost your home directory on the remote machine.
I trust you have a backup, because most common file systems can't easily recover deleted files. If you don't have a backup, boot the remote machine from system rescue cd and use photorec to try to recover the files onto a USB stick or removable drive.
