module main import os // basic example which shows how to use the Command function fn exec(path string) string { mut out := '' mut line := '' mut cmd := os.Command{ path: path } cmd.start() or { panic(err) } for { line = cmd.read_line() println(line) out += line if cmd.eof { return out } } return out } fn main() { mut out := '' exec("bash -c 'find /tmp/'") out = exec('echo to stdout') out = exec('echo to stderr 1>&2') println("'${out}'") // THIS DOES NOT WORK, is error, it goes to stderror of the command I run assert out == 'to stderr' }
