Does MacPorts have a version of rm that does secure removal of files (that is, scribbling over the disk so that info cannot be recovered)? I want this for files about my bank dealings---I'm not referring to files that come from MacPorts downloads.
The Mac OS X Finder features the "Secure Erase Trash" command in the Finder menu. You can place your files in the Trash, select "Secure Erase Trash", and your files are unrecoverable. You may be able to trigger "Secure Erase Trash" via AppleScript, which you could call from the command line using "osascript" if you wanted to.
If you want something more similar to "rm" which you can use on individual files from the Terminal, then the "shred" utility may be what you're looking for. It's part of the coreutils port (which installs it as "gshred").
Does MacPorts have a version of rm that (unlike Unix, but like Mac Os X) is undoable?
I would suggest: mv file ~/.Trash
Metaquestion: how would one research this issue before writing in to this list? I tried but failed.
I Googled "secure erase rm" and found a page describing the GNU shred utility. "port search shred" didn't show anything, so I Googled "GNU shred" and learned that it's part of the core-utils package. "port search core" showed that a port for core-utils exist.
