- The _s_t_r_i_p command removes the symbol table (the section named ".symtab",
- Elf section kind SHT_SYMTAB) and relocation bits ordinarily attached to
- the output of the assembler and loader. This is useful to save space
- after a program has been debugged.
-
- Unless option -_f is given, only objects marked with ELF type ET_EXEC (the
- type given to main programs) are stripped. See /_u_s_r/_i_n_c_l_u_d_e/_e_l_f._h for
- the type codes.
-
- The effect of the default _s_t_r_i_p is similar to use of the ----ssss option of _l_d.
-
- _S_t_r_i_p recognizes the following options:
-
- ----bbbb Same effect as the default behavior. This option, though
- accepted, is obsolete.
-
- ----ffff Allows stripping information from any ELF file (including
- relocatable object files and Dynamic Shared Objects) and any
- ELF file inside an archive.
-
- ----hhhh Removes symbol names from SHT_DYNSYM and/or SHT_SYMTAB section
- symbol entries marked STO_HIDDEN or STO_INTERNAL. Makes
- strings in certain string tables into all zeros. (Symbols may
- be marked STO_HIDDEN or STO_INTERNAL by the _l_d(1) options
- -_h_i_d_d_e_n__s_y_m_b_o_l or -_h_i_d_e_s__f_i_l_e.) This option saves no space in
- the object, so there is no point to using it on most ELF files.
-
- ----llll Strips line number information only from -n32 or -64 object
- files. Doesn't strip the ELF symbol table or debugging
- information other than the line number information. Does
- nothing on -32 object files.
-
- ----oooo _o_u_t_f_i_l_e
- Specifies a name for the output file. It is a mistake to
- specify more than one _n_a_m_e to strip, since only one stripped
- outputfile is created if ----oooo _o_u_t_f_i_l_e is specified. The output
- file is created with mode 0644.
-
- ----uuuu When combined with -o, the new output file has the current user
- ID and group ID. By default (without -u) -o applies the user
- ID and group ID of the input file to the output file. Ignored
- if -o not supplied.

-
-
-
- ----rrrr Same effect as the default behavior. This option, though
- accepted, is obsolete.
-
- ----ssss Strips some sections beyond the default strippable set.
- _p_i_x_i_e,_c_o_r_d, and some other object tools cannot be used on a dso
- or a.out with these additional sections stripped. This is
- intended for standalone programs (for which the space savings
- is more important than the ability to use object tools on the
- resulting file).
-
- ----kkkk When used with ----ssss this adds the .debug_frame section to the
- list of sections stripped. This option is not relevant for
- old-32bit ABI objects. When used without ----ssss the ----kkkk option does
- nothing at all. If the .debug_frame section (which only
- appears in n32 and 64 ABI objects) is stripped from an
- executable or DSO or object then C++ exception handling may
- silently work incorrectly. It is extremely unwise to use ----kkkk on
- any DSO (though if the DSO is never in use with C++ exceptions
- there is no harm in removing .debug_frame, how can one be sure
- that the DSO won't be used with C++ exceptions?). Use ----kkkk on an
- executable only if a) space saving on disk is of paramount
- importance and b) you know that no C++ exceptions can occur in
- the application (and preferably none can occur in any DSO it
- calls (directly or indirectly)).
-
- ----SSSS Suppress all messages (run silently).
-
- ----VVVV Prints, on _s_t_d_e_r_r, the version number of _s_t_r_i_p.
-
- ----xxxx Turns off stripping the ELF ".symtab" (SHT_SYMTAB) symbol table
- section from the object.

- any error, a non-zero value is returned to the environment with _e_x_i_t (_3).

- These options will be removed in a future release.

- Temporary files are created during execution. Up to three times the space
- of each original file being stripped may be needed while the program is
- in operation. Temporary files may be created in /_u_s_r/_t_m_p and in the
- directory given on the command line (if no directory is specified in the
- file pathname the current directory is assumed). If the command is strip
- /a/b/c then the directory /_a/_b must have permissions to allow file
- creation, writing, and reading. Whether /_a/_b/_c is a file (with or
- without multiple links) or a symbolic link to a file, the directory /_a/_b
- must allow file creation, writing, and reading. If /_a/_b/_c is a symbolic
- link then the true directory of the real file (which could be on a
- different machine or filesystem than /_a/_b) must also allow file creation,
- writing, and reading.
-
- The ----ssss option removes the line-table section removed by the ----llll option so
- using both is just like using the ----ssss option without using the ----llll option.
