DESCRIPTION
GNU strip discards all symbols from object files objfile.
The list of object files may include archives. At least one
object file must be given.
strip modifies the files named in its argument, rather than
writing modified copies under different names.
OPTIONS
-F bfdname
--target=bfdname
Treat the original objfile as a file with the object
code format bfdname, and rewrite it in the same format.
--help
Show a summary of the options to strip and exit.
--info
Display a list showing all architectures and object
formats available.
-I bfdname
--input-target=bfdname
Treat the original objfile as a file with the object
code format bfdname.
-O bfdname
--output-target=bfdname
Replace objfile with a file in the output format
bfdname.
-R sectionname

--remove-section=sectionname
Remove any section named sectionname from the output
file. This option may be given more than once. Note
that using this option inappropriately may make the
output file unusable.
-s
--strip-all
Remove all symbols.
-g
-S
-d
--strip-debug
Remove debugging symbols only.
--strip-unneeded
Remove all symbols that are not needed for relocation
processing.
-K symbolname
--keep-symbol=symbolname
Keep only symbol symbolname from the source file. This
option may be given more than once.
-N symbolname
--strip-symbol=symbolname
Remove symbol symbolname from the source file. This
option may be given more than once, and may be combined
with strip options other than -K.
-o file
Put the stripped output in file, rather than replacing
the existing file. When this argument is used, only one
objfile argument may be specified.
-p
--preserve-dates
Preserve the access and modification dates of the file.
-w
--wildcard
Permit regular expressions in symbolnames used in other
command line options. The question mark (?), asterisk
(*), backslash (\) and square brackets ([]) operators
can be used anywhere in the symbol name. If the first
character of the symbol name is the exclamation point
(!) then the sense of the switch is reversed for that
symbol. For example:
-w -K !foo -K fo*

would cause strip to only keep symbols that start with
the letters ``fo'', but to discard the symbol ``foo''.
-x
--discard-all
Remove non-global symbols.
-X
--discard-locals
Remove compiler-generated local symbols. (These usually
start with L or ..)
--only-keep-debug
Strip a file, removing any sections that would be
stripped by --strip-debug and leaving the debugging
sections.
The intention is that this option will be used in
conjunction with --add-gnu-debuglink to create a two
part executable. One a stripped binary which will
occupy less space in RAM and in a distribution and the
second a debugging information file which is only needed
if debugging abilities are required. The suggested
procedure to create these files is as follows:
called>
1.
create a file containing the debugging info.
1.
stripped executable.
1.
to add a link to the debugging info into the
stripped executable.
Note - the choice of ".dbg" as an extension for the
debug info file is arbitrary. Also the
"--only-keep-debug" step is optional. You could instead
do this:
1.
1.
1.
1.
ie the file pointed to by the --add-gnu-debuglink can be
the full executable. It does not have to be a file
created by the --only-keep-debug switch.

-V
--version
Show the version number for strip.
-v
--verbose
Verbose output: list all object files modified. In the
case of archives, strip -v lists all members of the
archive.
