GOTO(1) General Commands Manual GOTO(1)
NAME
goto - transfer command
SYNOPSIS
goto label [...]
DESCRIPTION
Goto is allowed only when the shell is taking commands from a seekable
command file (see lseek(2)).
The entire command file is searched for a line beginning with a : as
the first non-blank character, followed by one or more blanks, and then
the label. If such a line is found, goto repositions the command-file
offset to the line after the label and exits. This causes the shell to
transfer to the labelled line.
: is a special command which causes the shell to do nothing.
EXIT STATUS
The goto command exits with one of the following values:
0 The label was found.
1 The label was not found.
2 An error was detected.

COMPATIBILITY
The goto command from Version 6 (V6) UNIX requires : to be the first
character on the labelled line. Otherwise, the label cannot be found.
This port differs in that : may be preceded by blanks. This allows
labelled lines to be indented so that complex command files might be
easier to read and understand.
HISTORY
A goto command appeared as /bin/goto in Version 3 (V3) UNIX.
AUTHORS
This port of the 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 <
