*MacOS uses the MacPorts package manager to manage commands. If you haven’t installed it yet, please refer to the MacPorts installation instructions at the link below. Also, set an alias for the command so that you can call the command without conflicting with the existing environment. If you are using this blog for the first time, please refer to the following two articles to set up your environment.

preinstall

If the command not found appears in the terminal, install it using the following command and set an alias.

sudo port install git


echo 'alias git="/opt/local/bin/git"' >> ~/bashrc_folder/macports_alias

command

Executing the following command in the terminal should output a string similar to the following:

source ~/bashrc_folder/macports_alias


git clone https://github.com/trygfmi/type_check-command-path


cd type_check-command-path


cat alias_file


type cat


source ./alias_file

Click to open details

Advance confirmation

Enter the following command into the prompt and if command not found does not appear, it’s OK.

WSL2
git --version
MSYS2 MINGW64
git --version

*Windows has been confirmed to work with WSL2 and MSYS2 MINGW64. Please install WSL2 if possible, and if you are unable to set it up, you can run it by installing MSYS2, but there may be some commands that can only be run in WSL2. Please refer to the following article for instructions on how to install WSL2 and MSYS2.

preinstall

If the command not found appears in the prompt, please install it using the following command.

WSL2
sudo apt install git
MSYS2 MINGW64
pacman --sync git

command

By executing the following command at the prompt, you should get the following output:

WSL2
git clone https://github.com/trygfmi/type_check-command-path


cd type_check-command-path


cat alias_file


type cat


source ./alias_file


type cat
Detail 
cat is hashed (/usr/bin/cat)
cat is aliased to `echo "hello type command world"'
MSYS2 MINGW64
git clone https://github.com/trygfmi/type_check-command-path


cd type_check-command-path


cat alias_file


type cat


source ./alias_file


type cat
Detail 
cat is hashed (/usr/bin/cat)
cat is aliased to `echo "hello type command world"'

Afterword

Since cat is specified with the alias command, the original cat command will not be available after the source command, but this will be resolved by closing the terminal. There is a which command to obtain the path of a command, but even if you set an alias to cat as in the code below, the value output by which will not change.

which cat


alias cat="/test/path"


which cat

The first line of the output shows cat is hashed (/bin/cat) because the cat command is used with cat alias_file before executing type cat, so the cached path is referenced to execute the command efficiently.
