"foo" is not recognized as an internal or external command, operable program or batch file. Some early Unix shells produced the equally cryptic " foo: no such file or directory " again accurately describing what is wrong but confusing users.
In computing, specifically in Unix and Unix-like operating systems, a raw device is a special kind of logical device associated with a character device file that allows a storage device such as a hard disk drive to be accessed directly, bypassing the operating system's caches and buffers (although the hardware caches might still be used).
Support for command history means that a user can recall a previous command into the command-line editor and edit it before issuing the potentially modified command. Shells that support completion may also be able to directly complete the command from the command history given a partial/initial part of the previous command.
-i, do not classify the file further than to identify it as either: nonexistent, a block special file, a character special file, a directory, a FIFO, a socket, a symbolic link, or a regular file. Linux [6] and BSD [7] systems behave differently with this option and instead output an Internet media type ("MIME type") identifying the recognized ...
The command hdiutil attach -imagekey diskimage-class=CRawDiskImage -nomount <filename> causes a block device to appear in /dev as a regular disk device and subdevices for recognized partitions. Reads from and writes to those devices are sent to a user-mode helper process, which reads the data from the file or writes it to the file.
Binary-code compatibility (binary compatible or object-code compatible) is a property of a computer system, meaning that it can run the same executable code, typically machine code for a general-purpose computer central processing unit (CPU), that another computer system can run.
The acquisition was a success story for Maxtor, and the subsidiary had grown to generate $80 million in sales by 1992. [7] That year, Maxtor sold off Storage Dimensions to private investors. [7] In 1990, Maxtor entered the mass market with its purchase of the assets (but not the liabilities) of bankrupt MiniScribe in Longmont, Colorado. [8]
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices.It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots.
