spawn-default-shell v2.0.0
spawn-default-shell
Spawn shell command with platform default shell
master branch status
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/zshSHELL_EXECUTE_FLAGS=-l -cWarning: 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.
Install
