# install-protoc.sh
|
|
#
|
|
# This script installs the Protocol Buffers compiler (protoc) to the specified
|
|
# directory. 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.
|
|
#
|
|
# Note: This script requires internet connectivity to download the protoc binary.
