Trash Can is a recycle bin implementation for the command line. It is a set of scripts that can be run with ksh, bash, or zsh. It has commands for file removal, file restoration (to the original path), permanent deletion of particular files from the trash can, automatic purging of trash that is more than a certain number of days old, completely emptying the trash can, configuring trash can storage capacity, and displaying trash can disk usage. Trash is compressed to take up less room.
Binmay is a command line binary search and replace program. It allows one to specify a binary string (in hex) to search for and, optionally, a binary string to replace it with. One can mask both search and replace strings as one can mask an IP. It is handy for changing broken user SID/RIDs in ntuser.dat files after you move a profile from somewhere to somewhere else.
