rmd

An improved rm implementation able to remove duplicate files

Description

rmd is an rm reimplementation made in pure Rust. It is able to remove files and directories as usual but it also able to remove duplicate file in given directories recursively.

Duplicate file are found by comparing SHA256 hashes. When a file has an hash that has already been found it is removed immediately.

Installation

This tool can be easly installed from sources:

cargo install rmd

Usage

It works in an almost compatible way with the standard rm. To get a full help run:

rmd --help

But the most common scenarios includes:

• remove files, for example:

rmd FILE_A FILE_B 

• remove a directory, for example:

rmd -rf DIR_A

Additional Features

Remove Duplicates

• remove duplicates files in the current directory, and all sub directoris:

rmd -d

or remove duplicates files in a specified directory:

rmd -d /PATH/TO/DIRECTORY

Remove by Last Access

This functionality allows to remove file older or newer then a given time-specification.

Remove File older then time-spec

rmd --older <time-spec> [directory...]

Remove File newer then time-spec

rmd --newer <time-spec> [directory...]

rmd checks if the last access is before (so the file is older) or after (so the file is newer) then the time described by the time-specification. time-specification describes a relative amount of time (in seconds) in the past from the moment when the program is run.

time-specification format

[NT]+

Where:

• N is a number (1-9)
• T is a time descriptor
• + means one or more

Time Descriptor Table

Examples

rmd --older 2y4m5d

will remove in the current directory, and recursivelly in all sub directories, file with a last access time equal or before 2 year, 4 month and 5 days in the past from the time when the program is run.

rmd --newer 4h30m

will remove in the current directory, and recursivelly in all sub directories, file with a last access time equal or after 4 hour and 30 minutes in the past from the time when the program is run.

rmd --older 1m15d /home/user/temp-store

will remove in /home/user/temp-store and recursivelly in all sub directories, file with a last access time equal or before 1 mounth and 15 days in the past from the time when the program is run.

rmd --older 30s /home/user/wrong-downloads

will remove in /home/user/wrong-downloads and recursivelly in all sub directories, file with a last access time equal or after 30 seconds in the past from the time when the program is run.

Note

• When working in interactive mode and a remove file is a directory rmd prompts only once for the root directory
• newer, older, recursive are mutually exclusive.
