.TH GOTO 1 "@OSH_DATE@" "@OSH_VERSION@" "General Commands"
.SH NAME
goto \- transfer command
.SH SYNOPSIS
.B goto
\fIlabel\fR [\fI...\fR]
.SH DESCRIPTION
.B Goto
is allowed only when the shell is taking
commands from a seekable command file (see
.IR lseek (2)).
.PP
The entire command file is searched for a line beginning
with a \fB:\fR as the first non-blank character,
followed by one or more blanks,
and then the
.IR label .
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),
osh(1),
sh6(1)
.PP

.SH COMPATIBILITY
The
.B goto
command from Sixth Edition 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 Third Edition UNIX.
.SH LICENSE
