OS Binaries
If you want to execute a native binary from inside the interactive shell or as part of a CommandBox recipe, we allow this via the run
command. You can read the API docs for run
here.
Hint This behavior is dependent on your operating system.
Using run binary
run binary
Execute an operation system level command using the native shell. For Windows users, cmd.exe
is used. For Unix, /bin/bash
is used. Command will wait for the OS command to finish.
The binary must be in the PATH, or you can specify the full path to it. Your keyboard will pass through to the standard input stream of the process if it blocks for input and the standard output and error streams of the process will be bound to your terminal so you see output as soon as it is flushed by the process.
Using !binary
!binary
A shortcut for running OS binaries is to prefix the binary with !
. In this mode, any other params need to be positional. There is no CommandBox parsing applied to the command's arguments. They are passed straight to the native shell. As such, you don't need to escape any of the parameters for CommandBox when using this syntax.
Current Working Directory Aware
OS Commands you run are executed in the same working directory as CommandBox. This means you can seamlessly invoke other CLIs without ever leaving the interactive shell.
Building On
The output of native calls can be used in expressions or piped into other commands. Here's a Unix example that uses CFML functions from the command line to parse the parent folder from the current working directory:
Parsing Rules
When passing a command string for native execution, any piping, redirection, &&
or ||
will be processed on the CommandBox side. In the above example, the native !pwd
output is passed back to a CommandBox command.
Additionally, any expansions you put in your command string with backticks or System Setting placeholders will not be processed by CommandBox, but will be passed to the native OS directly.
In the event you want to have the piping done by the operating system OR you want expansions to be processed by CommandBox prior to passing to the OS, you can workaround this by echoing out what you want to run and then piping that to the run
command.
In the above example, written for Windows, the output of the echo
command has the package show name
expression expanded into the string and then the ENTIRE string is piped to run
where the pipe and the find
command are processed by Windows. Note, there is no need for preceding the command with !
when passing to run
since !
is just an alias for run
.
Setting the Native Shell
You can override the default native shell from /bin/bash
to any shell of your choosing, like zsh. This will let you use shell specific aliases. You can set your native shell property using the config set
command (i.e., config set nativeShell=/bin/zsh
)
