The "ed" command is a text editor used in Unix-like operating systems. The option "--quiet" is a command-line argument provided to the "ed" command, and it modifies the behavior of the editor.
When the "--quiet" option is used, it instructs "ed" to run in quiet mode. In this mode, the editor suppresses any error or diagnostic messages that it would normally display during its operation. The user will not see any output or notifications as they perform various editing operations.
This option is particularly useful in scripting or automation scenarios where the editor's activity needs to be silent and not generate any unnecessary output. It allows the "ed" command to be executed without any visual interruptions or feedback, making it suitable for non-interactive usage.
