go-bin-upgrade

go-bin-upgrade

Rebuild the binaries you have built in Go module mode installed in $GOPATH/bin.

Usage: go-bin-upgrade [-n] [-v] bin1 [bin2]...

Examples:

  • go-bin-upgrade -n godoc
  • (cd ~/go/bin ; go-bin-upgrade * )

Limitation: only binaries built in Go module mode can be rebuilt because they embed the module from which they have been built. Check go version -m on the binary for more info.

#!/usr/bin/env bash
# Upgrade Go binaries built in Go module mode and installed in $GOPATH/bin.
