![]() Provided that your account is authorized to use the sudo command, you use your own password when prompted after executing the command. Normally the command is run with a user called ' root', which has god-like privileges on the system. sudo Sudo is a command used to precede other commands which need to be run with an escalated role. Just about anything they can do can also be done by phpmyadmin. Mysql and mysqladmin These are command line utilities for connecting to and managing a MySQL database. Operations the command does on the screen ("verbose", -v), and This uncompresses (-x) project.tgz from the gzip format (-z), lists all Tar files are more commonly known as 'tarballs.' Drupal core is most often downloaded as a compressed tar file. Tar This is an archiving and unarchiving utility. This downloads the file at that URL (which happens to be Wget This is a command to download web pages or files from the net and save them to disk. This creates a symbolic link in the current directory to the directory Since the shortcut/alias is linked, rather than just a copy of the file or directory, changes to one are reflected in the other. You can create a link to a file or directory located somewhere else, and it will behave just like a copy of that file or directory. The one you will see mentioned most often is a 'symbolic link' (using the '-s' option switch), which behaves like a shortcut in Windows or an alias in the Macintosh Finder. Ln This command creates a filesystem link. Directories are also known as 'folders' in the Windows and Macintosh world. This copies the '' file, which is in the 'default'ĭirectory to the 'mysite' directory, where it is renamed 'settings.php'. The '-a' (for archive) option switch includes both '-r' and '-p' options.Įxample: cp default/ mysite/settings.php The '-r' (recursive) option switch also copies subdirectories and files. The '-p' (for preserve) option switch also copies permissions, ownerships, etc. cp This command copies files and directories. This deletes every file (except those starting with a dot) in the currentĭirectory. This deletes the settings.php file from the current directory. To remove a directory you need to use the '-r' (recursive) option. rm This command removes (i.e., deletes) files and/or directories. This will move all files (except those starting with a dot) in the currentįolder up one level. In general, to rename a file or a directory you 'move' it to its new name.Įxamples: mv settings.php Mv This command moves or renames files and directories. Modifying Linux, Unix, and Mac file permissions.These pages provide further details on file permissions: This changes the folder and everything inside it. This changes the permissions on the file (or folder) 'sites' so that everybody can read, The '-R' (for recursive) option "switch changes" the permissions on subdirectories and files as well. Some Unix command you'll see used: chmod This command changes the permissions on files and directories. Learning some of these *nix commands can help you be more productive, as well as give you insight into what your hosting control panel or GUI FTP client does. (translated) In this research, we applied Functgraph to create four apps, an app for making edible sandwiches, an app for folding clothes, an app for packing and mass-producing rabbit figures, and an app for making car toys, to deepen our understanding of Functgraph.References to Unix-like (*nix) commands in documentation or forum posts can be intimidating if you're not used to them, but sometimes "command line" is necessary for administering your system or fixing a problem. ![]() This clever custom 3D printing system, known as a “Functgraph”, can perform a wide variety of tasks such as building toy cars, packing rabbit figures, and folding clothes. It can be reproduced accurately, so there are no mistakes. I made a prototype from the idea of how easy it would be if I could cook when I woke up in the morning saying “OK Google, tomorrow’s breakfast is a sandwich”. Regarding the sandwich app, there are many ways to see the recipe, but in the end it has to be made by humans. Mechanical Engineer Yuto Kuroki and an engineering team from Meiji University in Tokyo have converted a working 3D printer into a nifty sandwich making robot that slides the meat and cheese onto crustless bread and then quite cleverly saws it in half.
