The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
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.
Using the 0x sequence form described previously, 0x22 can also be used, which additionally hides the " from the command interpreter. Several variables are provided, to be used in the command as placeholders for the values from each file. Variables are technically not required, but must be used if the command is to vary for each file.
Changes the permissions of a file or directory cp: Copies a file or directory dd: Copies and converts a file df: Shows disk free space on file systems dir: Is exactly like "ls -C -b".

Some commands, such as echo, false, kill, printf, test or true, depending on your system and on your locally installed version of bash, can refer to either a shell built-in or a system binary executable file. When one of these command name collisions occurs, bash will by default execute a given command line using the shell built-in. Specifying ...
The most notable example is the cd command, which changes the working directory of the shell. Since each executable program runs in a separate process , and working directories are specific to each process, loading cd as an external program would not affect the working directory of the shell that loaded it.
