File Sync Utility

The fsync is a file transfer program capable of local update.

Usage

Usage:
  fsync [flags] SRC DEST

Flags:
  -d, --delete    delete extraneous files from dest dirs
  -h, --help      help for fsync
  -v, --verbose   increase verbosity

where

  • SRC is a source (file or folder) to synchronize.
  • DEST is a destination folder, where source file or folder should be placed.

Why

There is a great tool named rsync, but it might be not available (for example, Windows doesn't have it). For sure, cwRsync can be installed and happy used. But I'd like to have owns (even if it is much humbler featured).

How it works

  1. Validate SRC and DEST input arguments.
  2. Check file in DEST folder:
    1. If file already exists - compare checksums of files and skip sync if equal.
    2. If file not exists:
      1. Copy SRC file to DEST temporary file.
      2. Compare checksums of files and fail if they differ.
      3. Rename DEST temporary file to DEST file.

Development

Update dependencies

go mod tidy
go mod vendor

Build

To make a cross-build, please see available platforms:

go tool dist list

For example, for linux run this command to create a binary file for linux/amd64 architecture:

GOOS=linux GOARCH=amd64 go build

For batch build use Makefile and run:

make build

It will create builds directory with archived binary files according to preconfigured set of platforms.
