How to launch Explorer from WSL

Introduction

I wanted to start Explorer from the command line like Git Bash inWSL (Windows Subsystem for Linux), so I tried to find out how to execute it.

The execution environment is as follows.

What I wanted to do

Git Bash allows you to run Explorer using the start command at the command prompt.

$ start explorer [Directory path]

In the same way, check with WSL to see if you can run Explorer from the command line.

result

As a result, WSL was able to run Explorer with the following command.

$ explorer.exe [Directory path]

Why you can execute files on the Windows side

I checked the contents of the environment variable PATH on the WSL side using the ʻenv command`.

$ echo $PATH | sed s/:/\\n/g | grep -Ei "/mnt/c/windows"
/mnt/c/Windows/system32
/mnt/c/Windows
/mnt/c/Windows/System32/Wbem
/mnt/c/Windows/System32/WindowsPowerShell/v1.0/
/mnt/c/WINDOWS/system32
/mnt/c/WINDOWS
/mnt/c/WINDOWS/System32/Wbem
/mnt/c/WINDOWS/System32/WindowsPowerShell/v1.0/
/mnt/c/WINDOWS/System32/OpenSSH/
/mnt/c/WINDOWS/system32
/mnt/c/WINDOWS
/mnt/c/WINDOWS/System32/Wbem
/mnt/c/WINDOWS/System32/WindowsPowerShell/v1.0/
/mnt/c/WINDOWS/System32/OpenSSH/

Apparently, WSL reflects the environment variables on the Windows side by default, so it seems that you can specify an executable file such as a standard Windows command.

Execute the command without specifying .exe

I understand how to execute it, but since it is a hassle to specify .exe each time and execute it, register an alias.

Aliase registration

Register the alias in the bash configuration file .bashrc and set it so that the command can be executed without .exe.

$ vim ~/.bashrc

The edit screen of vim will be opened, so add the contents to .bashrc as follows.

alias [Command name]='[Executable file name]'

I set it as follows.

# aliases
alias explorer='explorer.exe'

After editing, use the source command to reload .bashrc to reflect the alias.

$ source ~/.bashrc

After executing the source command, check if the command can be executed without .exe.

$ explorer .

I think you can now run it without .exe. By the way, you can check the list of set aliases with the ʻalias command`.
