.SH DESCRIPTION
GNU
.B strip
discards all symbols from the object files
.IR objfile .
The list of object files may include archives.
At least one object file must be given.

.P
.B strip
modifies the files named in its argument,
rather than writing modified copies under different names.

.SH OPTIONS
.TP
.B "\-F \fIbfdname"
.TP
.B "\-\-target=\fIbfdname"
Treat the original \fIobjfile\fP as a file with the object
code format \fIbfdname\fP, and rewrite it in the same format.

.TP
.B \-\-help
Show a summary of the options to
.B strip
and exit.

.TP
.B "\-I \fIbfdname
.TP
.B "\-\-input\-target=\fIbfdname"
Treat the original \fIobjfile\fP as a file with the object
code format \fIbfdname\fP.

.TP
.B "\-O \fIbfdname\fP"
.TP
.B "\-\-output\-target=\fIbfdname"
Replace \fIobjfile\fP with a file in the output format \fIbfdname\fP.

.TP
.B "\-R \fIsectionname\fP"
.TP
.B "\-\-remove\-section=\fIsectionname"
Remove the named section from the file.  This option may be given more
than once.  Note that using this option inappropriately may make the
object file unusable.

.TP
.B \-s
.TP
.B \-\-strip\-all
Remove all symbols.

.TP
.B \-S
.TP
.B \-g
.TP
.B \-\-strip\-debug
Remove debugging symbols only.

.TP
.B \-\-strip\-unneeded
Strip all symbols that are not needed for relocation processing.

.TP
.B \-N \fIsymbolname\fR
.TP
.B \-\-strip\-symbol=\fIsymbolname
Remove symbol \fIsymbolname\fP from the source file. This option
may be given more than once, and may be combined with other strip
options.

.TP
.B \-o \fIfile\fR
Put the stripped output in \fIfile\fR, rather than replacing the
existing file.  When this argument is used, only one \fIobjfile\fR
argument may be specified.

.TP
.B \-p
.TP
.B \-\-preserve-dates
Preserve the access and modification dates of the file.

.TP
.B \-x
.TP
.B \-\-discard\-all
Remove non-global symbols.

.TP
.B \-X
.TP
.B \-\-discard\-locals
Remove compiler-generated local symbols.
(These usually start with ``L'' or ``.''.)

.TP
.B \-K \fIsymbolname\fR, \fB\-\-keep\-symbol=\fIsymbolname
Copy only symbol \fIsymbolname\fP from the source file. This option
may be given more than once.

.TP
.B \-N \fIsymbolname\fR, \fB\-\-strip\-symbol=\fIsymbolname
Do not copy symbol \fIsymbolname\fP from the source file. This option
may be given more than once, and may be combined with strip options
other than \fB\-K\fR.

.TP
.B \-v
.TP
.B \-\-verbose
Verbose output: list all object files modified.  In the case of
archives,
.B "strip \-V"
lists all members of the archive.

.TP
.B \-V
.TP
.B \-\-version
Show the version number for \fBstrip\fP and exit.
