pipe.SetEnvVar("PIPE_VAR", "outer"),
pipe.Line(
pipe.SetEnvVar("PIPE_VAR", "inner"),

)

}示例2: TestLineNesting
func (S) TestLineNesting(c *C) {

}示例4: Pipe
// Pipe connects the output of one Executable to the input of the next
// Executable in the list. The result is an Executable that, when run, returns
// the output of the last Executable run, and any error it might have had.
//
// If any of the Executables fails, no further Executables are run, and the
// failing Executable's stderr and error are returned.

ps := make([]pipe.Pipe, len(cmds))
for i, c := range cmds {

}

// PipeWith functions like Pipe, but runs the first command with stdin as the
// input.
