Method: Subprocess.call

Defined in:

lib/subprocess.rb

.call(cmd, opts = {}) {|process| ... } ⇒ ::Process::Status

Note:

If you call this function with ‘:stdout => PIPE` or `:stderr => PIPE`, this function will block indefinitely as soon as the OS’s pipe buffer fills up, as neither file descriptor will be read from. To avoid this, use Subprocess::Process#communicate from a passed block.

Call and wait for the return of a given process.

• cmd (Array<String>) —

• opts (Hash) (defaults to: {}) —
