strip - strip symbol and line number information from an object file
strip [-l] [-x] [-r] [-V] [-U] filename ...
strip removes the symbol table and line number information from object
files, including archives. Thereafter, no symbolic debugging access
is available for that file; thus, this command is normally run only on
production modules that have been debugged and tested. The effect is
nearly identical to using the -s option of ld.
The amount of information stripped from the symbol table can be
controlled by using any of the following options:
-l Strip line number information only; do not strip any
symbol table information.
-x Do not strip static or external symbol information.
Note that the -l and -x options are synonymous because
the symbol table contains only static and external
symbols. Either option strips only symbolic debugging
information and unloadable data.
-r Reset the relocation indexes into the symbol table (SOM
only). Obsolete for ELF files. This option allows strip
to be run on relocatable files, in which case the effect
is also to strip only symbolic debugging information and
-V Print the version of the strip command on the standard
-U Print the usage menu.
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 strip is executed on an archive file (see ar(4)), the archive
symbol table is removed. The archive symbol table must be restored by
executing ar with its s operator (see ar(1)) before the archive can be
used by the ld command (se ld(1)). strip instructs the user with
appropriate warning messages when this situation arises.
The purpose of this command is to reduce file storage overhead
consumed by the object file.

The following internationalization variables affect the execution of
LANG Determines the locale category for native language, local customs
and coded character set in the absence of LC_ALL and other LC_*
environment variables. If LANG is not specified or is set to the
empty string, a default of C (see lang(5)) is used instead of
Determines the values for all locale categories and has
precedence over LANG and other LC_* environment variables.
Determines the locale that should be used to affect the format
and contents of diagnostic messages written to standard error.
Determines the locale category for numeric formatting.
Determines the locale category for character handling functions.
Determines the location of message catalogues for the processing
If any internationalization variable contains an invalid setting,
strip behaves as if all internationalization variables are set to C.
In addition, the following environment variable affects strip:
Specifies a directory for temporary files (see tmpnam(3S)).
International Code Set Support
Single- and multi-byte character code sets are supported.
strip: name: cannot open name cannot be read.
strip: name: bad magic name is not an appropriate object file.
strip: name: relocation entries present; cannot strip
name contains relocation entries and the
-r option was not specified. Symbol
table information cannot be stripped.
Hewlett-Packard Company - 2 - HP-UX Release 11i: November 2000
Strip symbol table and debug information from the shared library
libfoo.sl in the current directory to reduce its size. Symbol
information required to use the library is preserved:
/var/tmp/SGSstrp* temporary files
ar(1) create archived libraries
as(1) translate assembly code to machine code
cc(1) invoke the HP-UX C compiler
ld(1) invoke the link editor
a.out(4) assembler, compiler, and linker output
ar(4) archive format
strip: SVID2, SVID3, XPG2, XPG3, XPG4, POSIX.2
