directory

问题 I've just started learning r and confused by the following question given in the course: Create a directory in the current working directory called “testdir2” and a subdirectory for it called “testdir3”, all in one command by using dir.create() and file.path(). I couldn't get it to accept my answer and then found another site online giving the answers. This is the answer the other site gave: dir.create(file.path('testdir2', 'testdir3'), recursive = TRUE) After copy/pasting this answer it

问题 Looking for a clean Python Wget solution of downloading multiple files at once.

问题 I want to read files from a config folder at the directory where the executable is located. I do that using the following functions: use std::env; // add part of path to te path gotten from fn get_exe_path(); fn get_file_path(path_to_file: &str) -> PathBuf { let final_path = match get_exe_path() { Ok(mut path) => { path.push(path_to_file); path } Err(err) => panic!("Path does not exists"), }; final_path } // Get path to current executable fn get_exe_path() -> Result<PathBuf, io::Error> { /

问题 Is it possible to change around directories using the fork command? Without going too much into my code I have the following: childpid = fork(); if (childpid >= 0) { if (childpid == 0) { ret = execvp(argv[0],argv); exit(ret); } else { waitpid(childpid,&status,0); ret = WEXITSTATUS(status); } } The above works fine when I'm entering basic command like ls , pwd , etc.. Is it possible to implement a way to use the cd function? I can type the command cd .. but it doesn't do anything. For example

问题 I'm using jenkins 2.0 with Cloudbees Folder plugin as this allow me to create multiple similar projects. The jobs in each folder can be factored out leaving a top level job that can then call a parameterised job. I want to place the parameterised job in a Generic folder and then call them from a pipeline script. So within the jenkins browser I would have 3 folder : ProjA, ProjB and Generic. Under ProjA I have a pipeline job that needs to build a job called TestJib in the generic folder. My
