Exploring Behavior When Running cmd.exe from WSL Bash

Introducing verification of behavior when running cmd.exe from WSL Bash in Linux WSL Bash on Windows.

Only the first cd is executed

``` cmd.exe - <

Both are executed

``` cmd.exe - <

For some reason it errors

``` cmd.exe - <

C:\Users\ifgm2>set ATOM_HOME=C:\.atoms\.atom & atom
net.js:200
    this._handle.open(options.fd);
                 ^

Only the first command is executed

``` cmd.exe - <

Both are executed

``` cmd.exe /C "cd & cd" ```

Nothing is output and nothing is executed

``` cmd.exe /C <<'EOT' cd cd EOT ```

Nothing is output and nothing is executed

``` cmd.exe /C <<'EOT' set ATOM_HOME=C:.atoms.atom02 atom EOT ```

Nothing is output and nothing is executed

``` cmd.exe /C <<'EOT' set ATOM_HOME=C:.atoms.atom02 & atom EOT ```

Both are executed

``` cmd.exe /C 'set ATOM_HOME=C:.atoms.atom02 & atom' ``` ## Batch file verification ``` cat > hoge.bat cd cd ```

Logs into prompt

``` cmd.exe hoge.bat ```

Errors (bug)

``` cmd.exe /C hoge.bat ``` ``` 'hoge.bat' is not recognized as an internal or external command, operable program or batch file. ``` [Execute Batch file in Windows Subsystem for Linux - Stack Overflow](https://stackoverflow.com/questions/48582952/execute-batch-file-in-windows-subsystem-for-linux) ## Conclusion When you want to execute multiple commands, don't use batch files or here documents, but write them concatenated with &. e.g. cmd.exe /C 'set ATOM_HOME=C:\.atoms\.atom02 & atom'
