    Spawn shell command with platform default shell

    Build Status AppVeyor Build Status master branch status

    NPM Badge

    Like child_process.spawn with shell: true option but a bit more convenient and customizable. You can just pass the command as a string, and it will be executed in the platform default shell. Used in concurrently.

    // If we are in Linux / Mac, this will work
    const defaultShell = require('spawn-default-shell');
    const child = defaultShell.spawn('cat src/index.js | grep function');
    Platform Command
    Windows cmd.exe /c "...". If COMSPEC env variable is defined, it is used as shell path.
    Mac /bin/bash -l -c "..."
    Linux /bin/sh -l -c "..."

    You can always override the shell path by defining these two environment variables:

    • SHELL=/bin/zsh
    • SHELL_EXECUTE_FLAGS=-l -c Warning: execute flag must be the last flag.

    All sh variants will be called with -l flag (--login). It invokes the shell as a non-interactive login shell. In bash it means:

    When bash is invoked as an interactive login shell, or as a non-inter- active shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

    When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.
