# install-protoc.sh
|
|
#
|
|
# This script installs the Protocol Buffers compiler (protoc) on the local
|
|
# machine. It is used to generate code from .proto files for gRPC communication.
|
|
# The script downloads the protoc binary from the official GitHub repository and
|
|
# installs it in the system.
|
|
#
|
|
# Usage: ./install-protoc.sh [INSTALL_PATH]
|
|
#
|
|
# Arguments:
|
|
# INSTALL_PATH: The path where the protoc binary will be installed (optional).
|
|
# If not provided, the script will install the binary in the the
|
|
# directory named by the GOBIN environment variable, which
|
|
# defaults to $GOPATH/bin or $HOME/go/bin if the GOPATH
|
|
# environment variable is not set.
|
|
#
|
|
# Note: This script requires internet connectivity to download the protoc binary.
