CLIs are often used by programmers and system administrators, in engineering and scientific environments, and by technically advanced personal computer users. CLIs are also popular among people with visual disability, since the commands and feedbacks can be displayed using Refreshable Braille displays.
A program that implements such a text interface is often called a command-line interpreter or shell. Examples include the various Unix shells (sh, ksh, csh, tcsh, bash, etc.), the historical CP/M, and MS-DOS/IBM-DOS's COMMAND.COM, the latter two based heavily on DEC's RSX and RSTS CLIs. (DOS, i.e. MS-DOS/IBM-DOS, is actually is based on CP/M, DOS having been originally written as a substitute for CP/M-86 when its release was delayed.)
CLI интерфейси се използват често от програмисти и системни администратори, в инженерните и научни среди. Популярни са също сред хората със зрителни увреждания, тъй като командите както и получаваната обратно информация могат да се визуализират чрез използването на т.нар. [[брайлови дисплеи]].
