리눅스에서는 clear;ls;clear 식으로 하면되는데

MS 에서는 &로 하면되고

&&는 앞이 정상종료면 뒤를 수행하는 식이군


Using multiple commands and conditional processing symbols

You can run multiple commands from a single command line or script using conditional processing symbols. When you run multiple commands with conditional processing symbols, the commands to the right of the conditional processing symbol act based upon the results of the command to the left of the conditional processing symbol. For example, you might want to run a command only if the previous command fails. Or, you might want to run a command only if the previous command is successful.

You can use the special characters listed in the following table to pass multiple commands.

CharacterSyntaxDefinition

& [...]

command1 & command2

Use to separate multiple commands on one command line. Cmd.exe runs the first command, and then the second command.

&& [...]

command1 && command2

Use to run the command following && only if the command preceding the symbol is successful. Cmd.exe runs the first command, and then runs the second command only if the first command completed successfully.

|| [...]

command1 || command2

Use to run the command following || only if the command preceding || fails. Cmd.exe runs the first command, and then runs the second command only if the first command did not complete successfully (receives an error code greater than zero).

( ) [...]

(command1 & command2) 

Use to group or nest multiple commands.
