STRIP(1)                             SysV                             STRIP(1)



NAME
     strip - strip symbol and line number information from a common object
     file

SYNOPSIS
     strip [-l] [-x] [-b  [-r] [-V] [ -Aa] filename . . .

DESCRIPTION
     The strip command strips the symbol table and line number information
     from common object files, including archives.  Once this has been done,
     no symbolic debugging access is available for that file; therefore, this
     command is normally run only on production modules that have been
     debugged and tested. By default, enough information is saved to allow
     traceback information to be obtained from stripped files.

     The amount of information stripped from the symbol table can be
     controlled by using any of the options listed below:

OPTIONS
     -l        Strips line number information only; does not strip any symbol
               table information.

     -x        Does not strip static or external symbol information.

     -b        Same as the -x option, but also does not strip scoping
               information (e.g., beginning and end of block delimiters).

     -r        Does not strip static or external symbol information, or
               relocation information.

     -V        Prints the version of the strip command executing on the
               standard error output.

     -Aa       Strips .blocks and .lines sections of common object files so
               that traceback information is no longer available.

     If there are any relocation entries in the object file and any symbol
     table information is to be stripped, strip complains and terminates
     without stripping filename unless the -r option is used.

     If you use strip on a common archive file [see ar(4)] the archive symbol
     table and module table are removed.  You must restore the archive symbol
     table by executing  ar(1) with the s option before the archive can be
     link-edited by ld(1). strip produces appropriate warning messages when
     this situation arises.

     strip is used to reduce the file storage overhead taken by the object
     file.

FILES
     TMPDIR/strp*          temporary files

     TMPDIR is usually /usr/tmp but can be redefined by setting the
     environment variable TMPDIR [see tempnam() in tmpnam(3S)].

DIAGNOSTICS
     strip:  name:  cannot open
                           if name cannot be read.

     strip:  name:  bad magic
                           if name is not an appropriate common object file.
