If such a line is found, .B goto repositions the command-file offset to the line after the label and exits. This causes the shell to transfer to the labelled line. .PP \fB:\fR is a special command which causes the shell to do nothing. .SH "EXIT STATUS" The .B goto command exits with one of the following values: .TP 0 The label was found. .TP 1 The label was not found. .TP 2 An error was detected. .SH "SEE ALSO" if(1), @EBN@(1), @TBN@(1) .PP Etsh home page: https://etsh.nl/ .SH COMPATIBILITY The .B goto command from Version 6 (V6) UNIX requires \fB:\fR to be the first character on the labelled line. Otherwise, the label cannot be found. .PP This port differs in that \fB:\fR may be preceded by blanks. This allows labelled lines to be indented so that complex command files might be easier to read and understand. .SH HISTORY A .B goto command appeared as .I /bin/goto in Version 3 (V3) UNIX. .SH AUTHORS This port of the .B goto command is derived from Version 6 (V6) UNIX /usr/source/s1/goto.c. It was written by Ken Thompson of Bell Labs. Jeffrey Allen Neitzel .RI < jan@etsh.nl > ported and maintains it as .IR goto (1). .SH LICENSE See either the LICENSE file which is distributed with .B @EBN@ or https://etsh.nl/license/ for full details.
