GNU Info (ed.info)DiagnosticsDiagnostics *********** When an error occurs, if `ed''s input is from a regular file or here document, then it exits, otherwise it prints a `?' and returns to command mode. An explanation of the last error can be printed with the `h' (help) command. If the `u' (undo) command occurs in a global command list, then the command list is executed only once. Attempting to quit `ed' or edit another file before writing a modified buffer results in an error. If the command is entered a second time, it succeeds, but any changes to the buffer are lost. `ed' exits with 0 if no errors occurred; otherwise >0. automatically generated by info2www version 1.2.2.9 |
