clear is a computer
operating system
command which is used to bring the command line on top of the
computer terminal. It is available in various
Unix shells on
Unix and
Unix-like operating systems as well as on other systems such as
KolibriOS.
[1]
Depending on the system, clear uses the
terminfo or
termcap
database, as well as looking into the environment for the
terminal type in order to deduce how to clear the screen. The
Unix command clear takes no arguments and is roughly analogous to the command
cls on a number of other operating systems.
In ISO 9995-7 specifies that the following symbol be used to indicate this function on a keyboard, which is included in Unicode as: 竡 CLEAR SCREEN SYMBOL. [2]
One may use the
reset command to erase every previous command.
The clear command appeared in 2.79
BSD on February 24, 1979. Later, in 1985, the command was also included in
Unix 8th edition.
