How Can I Remove File Paths from Go Binaries?

Removing File Paths from TEXT Directives in Go Binaries

When building Go binaries using go build, one may notice that the resulting executable contains file paths in its assembly code. Removing this information can be desirable for security or privacy reasons.

Using -trimpath Flags

To remove file paths from TEXT directives in Go binaries, the -trimpath flag can be used. This flag allows us to specify a prefix to remove from the recorded source file paths.

To use this flag, add it to the -gcflags and -asmflags arguments of the go build command. For example:

CGO_ENABLED=0 go build -v -a -ldflags="-w -s" \
    -gcflags=-trimpath=/Users/myuser/dev/go/src \
    -asmflags=-trimpath=/Users/myuser/dev/go/src \
    -o ./fooapi spikes/mongoapi.go

This command will remove the specified prefix from the file paths in the resulting executable.

Using strip Tool

The strip tool can also be used to remove symbols from ELF binaries, including file paths. However, it is not recommended for use with Go binaries, as it can lead to broken executables or unexpected behavior.

More Information

The -trimpath flag is a more reliable and consistent method for removing file paths from Go binaries. It is also supported by the Go toolchain, providing a stable and effective solution.

By using the -trimpath flag, you can generate Go binaries that have reduced file path information, improving security and privacy.
