シェルスクリプトから関数を呼び出すと、コマンドが見つかりません。

caffeのインストールに使用するシェルスクリプトがありますが、使用するときシェン関数呼び出しのコマンドが見つかりませんエラーを表示するコマンド。コードは以下のように表示されます。

#!/bin/bash

# This script installs (or at least, attempts to install) Caffe in CPU mode

# * protobuf

# * gflags
# * glog
# * opencv
# * hdf5
# * python2
# * pip
# * libpng (recent version required for freetype)
# * automake (recent version required for freetype)
