MST (Move & Symlink Tool)

MST searches for large or old files and moves them to another drive (e.g. external hard disk) to avoid filling up your own

Windows OS is now supported by all functions! Not all functions are implemented yet! Right now MST is in an alpha stage. Attention! It is strongly discouraged to run with sudo rights or run with system / program files

Please report unchecked bugs via Issue!

Requirements

• Go compiler (v1.15)

Installation

git clone https://github.com/bstnbuck/MST.git

To build the program run following commands:

Linux:

• cd mst
• go build .
• ./mst + flags

Windows:

• move into program directory
• go build .
• Using CMD/Powershell (with Administrator privileges!): mst.exe + flags

Usage:

How it works:

• put a external HDD into your server / computer and mount it
• MST moves bigger or older files to new HDD and makes a symbolic link between them
• this is helpful, for files of download-sites.

Arguments: -m -size -days -dest -src -help -h -log -a -depth

• -m -> Select running mode 0 = file size (default); 1 = days; 2 = dir size (not implemented yet)
• -size -> Archive files by file size (default 20MB)
• -days -> Archive files by days (last modified) (default 60 days)
• -dest (required) -> Specify destination path (like: "/var/www/newPath/")
• -src (required) -> Specify source path (like: "/var/www/newPath/")
• -help -h -> see this help
• -log -> turn logging on (default = false)
• -save -> save system log file with actual date(default = false)
• -a -> analyze all files that could be archived (default = false)
• -reset -> reset all changes of last run, optional with -log
• -remove -> remove all changes of last run, optional with -log
• -filename -> choose other systemLog file for -reset or -remove

Status-Codes

0=Success; 1=Failure; 2=Info; 3=Modified; 4=User Interrupt; 9=Not implemented

---

Examples

• -m 1 -days 360 -src "/test/testdrive/" -log -a (MST analyze within elapsed 360 days and search in directory and log all commands)
• (-m 0) -size 2 -src "/test/testDrive/" -dest "/test/testPaste/" -log (MST with filesize = 2 MB and logging)
• -h (or -help) (prints help)
• -reset -filename "systemLog2020-6-27-12-11-19.log" -log

Information

• MST only runs with Linux and Windows OS.
• Tested on Windows 10, Debian 10 and Ubuntu 18/20.
• Due to Windows need a special flag to make a symlink you have to start CMD/Powershell with Administrator privileges.

The following is still being implemented

• Special implementation for ILIAS
