.SH NAME
ranlib \- generate an index to an archive
.SH SYNOPSIS
.IX Header "SYNOPSIS"
ranlib [\fB\-\-plugin\fR \fIname\fR] [\fB\-DhHvVt\fR] \fIarchive\fR
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBranlib\fR generates an index to the contents of an archive and
stores it in the archive.  The index lists each symbol defined by a
member of an archive that is a relocatable object file.
.PP
You may use \fBnm \-s\fR or \fBnm \-\-print\-armap\fR to list this index.
.PP
An archive with such an index speeds up linking to the library.
.PP
The GNU \fBranlib\fR program is another form of GNU \fBar\fR; running
\&\fBranlib\fR is completely equivalent to executing \fBar \-s\fR.
.SH OPTIONS
.IX Header "OPTIONS"
.IP \fB\-h\fR 4
.IX Item "-h"
.PD 0
.IP \fB\-H\fR 4
.IX Item "-H"
.IP \fB\-\-help\fR 4
.IX Item "--help"
.PD
Show usage information for \fBranlib\fR.
.IP \fB\-v\fR 4
.IX Item "-v"
.PD 0
.IP \fB\-V\fR 4
.IX Item "-V"
.IP \fB\-\-version\fR 4
.IX Item "--version"
.PD
Show the version number of \fBranlib\fR.
.IP \fB\-D\fR 4
.IX Item "-D"
Operate in \fIdeterministic\fR mode.  The symbol map archive member\*(Aqs
header will show zero for the UID, GID, and timestamp.  When this
option is used, multiple runs will produce identical output files.
.Sp
If \fIbinutils\fR was configured with
\&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
default.  It can be disabled with the \fB\-U\fR option, described
below.
.IP \fB\-t\fR 4
.IX Item "-t"
Update the timestamp of the symbol map of an archive.
.IP \fB\-U\fR 4
.IX Item "-U"
Do \fInot\fR operate in \fIdeterministic\fR mode.  This is the
inverse of the \fB\-D\fR option, above: the archive index will get
actual UID, GID, timestamp, and file mode values.
.Sp
If \fIbinutils\fR was configured \fIwithout\fR
\&\fB\-\-enable\-deterministic\-archives\fR, then this mode is on by
default.
.IP \fB@\fR\fIfile\fR 4
.IX Item "@file"
Read command\-line options from \fIfile\fR.  The options read are
inserted in place of the original @\fIfile\fR option.  If \fIfile\fR
does not exist, or cannot be read, then the option will be treated
literally, and not removed.
.Sp
Options in \fIfile\fR are separated by whitespace.  A whitespace
character may be included in an option by surrounding the entire
option in either single or double quotes.  Any character (including a
backslash) may be included by prefixing the character to be included
with a backslash.  The \fIfile\fR may itself contain additional
@\fIfile\fR options; any such options will be processed recursively.
