The default behavior of the mv and cp commands is to clobber their destination file if it already exists. This behavior may be overridden by invoking or aliasing the commands with the -i switch, causing the commands to prompt the user before overwriting the destination file, or -n to not transfer source files with a naming conflict.
Canaries or canary words or stack cookies are known values that are placed between a buffer and control data on the stack to monitor buffer overflows. When the buffer overflows, the first data to be corrupted will usually be the canary, and a failed verification of the canary data will therefore alert of an overflow, which can then be handled, for example, by invalidating the corrupted data.
A related ambiguity arises when a filename is moved to an existing directory. By default, mv would handle this as one trying to move a name inside this directory. GNU mv has a -T switch for disabling this assumption and try to overwrite the directory instead. An inverse -t makes the move-to-directory operation explicit. [4]
git clone [URL], which clones, or duplicates, a git repository from an external URL. git add [file] , which adds a file to git's working directory (files about to be committed). git commit -m [commit message] , which commits the files from the current working directory (so they are now part of the repository's history).
In computing, cp is a command in various Unix and Unix-like operating systems for copying files and directories.The command has three principal modes of operation, expressed by the types of arguments presented to the program for copying a file to another file, one or more files to a directory, or for copying entire directories to another directory.
where name_of_directory is the name of the directory one wants to create. When typed as above (i.e. normal usage), the new directory would be created within the current directory. On Unix and Windows (with Command extensions enabled, [15] the default [16]), multiple directories can be specified, and mkdir will try to create all of them.
On these computers, users can access a Unix-like command-line interface by running the terminal emulator program called Terminal, which is found in the Utilities sub-folder of the Applications folder, or by remotely logging into the machine using ssh. Z shell is the default shell for macOS; Bash, tcsh, and the KornShell are also provided.
