sys_process

Runs a system process with pipe access.

Target type

Signature

1sys_process(cmd::string= ?, args= ?, env= ?, user::string= ?)

Runs a system process with pipe access.

sys_process constructs or identifies a LaiRu value type. sys_process interacts with logs or child processes. Quote external arguments carefully and keep process output handling explicit.

Parameters

cmd: Optional value of type string. Supply cmd positionally unless the signature shows a keyword form.
args: Optional value. Supply args positionally unless the signature shows a keyword form.
env: Optional value. Supply env positionally unless the signature shows a keyword form.
user: Optional value of type string. Supply user positionally unless the signature shows a keyword form.

Examples

Basic call

1local(p) = sys_process('/bin/echo', array('hi'))

The example keeps process or logging behavior explicit so failures are visible.

Run a process and read output

1[2local(p) = sys_process3#p->open('/bin/echo', array('hello from lairu'))4local(out) = #p->read->decodeBytes5local(status) = #p->wait6#p->close7#out + 'status=' + #status8]

Close process handles when you are done with them.
