It may be difficult for a new user to become familiar with all the commands and options available, compared with the icons and drop-down menus of a graphical user interface, without reference to manuals.
The old Unix lint program is an early example. For debugging electronic hardware (e.g., computer hardware ) as well as low-level software (e.g., BIOSes , device drivers ) and firmware , instruments such as oscilloscopes , logic analyzers , or in-circuit emulators (ICEs) are often used, alone or in combination.
The Bourne shell (sh) is a shell command-line interpreter for computer operating systems.It first appeared on Version 7 Unix, as its default shell. Unix-like systems continue to have /bin/sh—which will be the Bourne shell, or a symbolic link or hard link to a compatible shell—even when other shells are used by most users.
