README for go-progs

What is this?

This is a collection of golang programs I wrote for my daily use. Most of them walk the file system and do interesting things - the FS walk being done in parallel/concurrent manner. These tools use the concurrent FS walker library go-walk.

Brief Description of the tools

  • godu -- an opinionated and simpler reimplementation of du(1).
  • ghash -- walk a file system and generate strong checksums of every file. Supports a variety of cryptographic checksums.
  • finddup -- finds duplicate files in a file system tree; files with the same strong checksum are considered identical.
  • deadlinks -- walk the file system and find dead symlinks.
  • hexlify -- print the contents of files/stdin in a variety of encoded formats (hex, base64, hexdump(1) style etc.)
  • ifaddr - prints the network interfaces and their IP addresses.

All the tools have their own "help" accessible via the -h or --help command line option.

How do I build it?

You'll need GNUmake 4.0 or later and a golang 1.21 or later:

git clone https://github.com/opencoff/go-progs
cd go-progs
gmake

The binaries will be in ./bin/$HOSTOS-$ARCH/ where $HOSTOS is the host OS where you are building (e.g., openbsd) and $ARCH is the CPU architecture (e.g., amd64).

If you do not have GNUmake, you can still build each program; eg.,:

./build -s ./godu
