Currently KTrash moves all deleted files to the filesystem containing $HOME. It is unaware of files on other volumes that have been deleted by Konqueror (for example /mnt/knoppix/.Trash-0).
Like Konqueror, KTrash will backup files of the same name by appending _1, _2, etc. and remember the file’s original location.
AFAIK KTrash can handle all unusual filenames, and in a manner consistent with Konqueror. It is possible that exceptions exist as this is a little technical %-/
KTrash -l will list the sizes of all trashed files/directories, and sort output.
KTrash has a safety feature. If the first arg is "mv", it will exit. To trash a file named "mv" use "KTrash -- mv".
The KTrash utility can be used to quickly remove (and optionally
restore) files spread around a directory tree.
To remove all files matching "*ounce*":
find /opt/kde -iname "*ounce*" | xargs KTrash
and to restore:
KTrash -R "*"
