For example, in DOS 5, if the current directory is C:\TEMP, then TRUENAME command.com will display C:\TEMP\COMMAND.COM (which does not exist), not C:\DOS\COMMAND.COM (which does and is in the PATH). This command displays the UNC pathnames of mapped network or local CD drives. This command is an undocumented DOS command.
The BASIC extension adds disk handling commands, which can be used with any device because they use CMD style commands. CD – change working directory; CDOPEN – open CD-ROM tray; CDCLOSE – close CD-ROM tray; CHANGE – change device number; DATE – print date and time; DEF – redefine function keys; DIR – normal directory listing
The command is analogous to the Stratus OpenVOS change_current_dir command. [9] cd is frequently included built directly into a command-line interpreter. This is the case in most of the Unix shells (Bourne shell, tcsh, bash, etc.), cmd.exe on Microsoft Windows NT/2000+ and Windows PowerShell on Windows 7+ and COMMAND.COM on DOS/ Microsoft ...
It also contains subsets of the standard DOS commands and CP/M commands – for example, it has both a built-in COPY command, and a PIP utility, both of which copy files. The CD command can assign one of the three drives N:, O: or P: to a directory on a different drive, in a similar manner to the MS-DOS command SUBST. For example, CD N:=C:\DATA ...
MS-DOS/PC DOS versions 4.0 and earlier assign letters to all of the floppy drives before considering hard drives, so a system with four floppy drives would call the first hard drive E:. Starting with DOS 5.0, the system ensures that drive C: is always a hard disk, even if the system has more than two physical floppy drives.
More importantly, the DOS system, which handles files and disk partitioning, manages the disk storage system. [10] Moreover, while IO.SYS is the kernel file of MS-DOS 7, JO.SYS is an alternate filename for IO.SYS that is used for "specific purposes" in MS-DOS 7. JO.SYS supports booting from a CD-ROM drive or a hard disk. [14]

All versions of Microsoft Windows have had an MS-DOS or MS-DOS-like command-line interface called MS-DOS Prompt which redirected input to MS-DOS and output from MS-DOS to the MS-DOS Prompt, or, in later versions, Command Prompt. This could run many DOS and variously Win32, OS/2 1.x and POSIX command-line utilities in the same command-line ...
