FS Diff

A tool to summarize a directory and then compare it at a later date to that summary.

Build

This tool requires the Go 1.16 toolchain to be installed locally.

$ make build

Run

Begin by summarizing an existing directory:

$ bin/fsdiff -dir example

This will produce sum.s2 and diff.s2. The diff file contains a list of all files that have been added, removed or changed.

Update the example directory and run the fsdiff again.

$ echo "new" > example/new
$ bin/fsdiff -dir example -sum sum.s2

To read the contents of these files, use the included debug tool.

$ bin/debug -sum sum.s2 -diff diff.s2
