strip - strip symbol table, debugging and line number information from an object file SYNOPSIS
strip [-lVx] file... DESCRIPTION
The strip command removes the symbol table SHT_SYMTAB and its associated string table, debugging information, and line number information from ELF object files. That is, besides the symbol table and associated string table, the following sections are removed: .line .debug* .stab* Once this stripping process has been done, limited symbolic debugging access is available for that file. Therefore, this command is nor- mally run only on production modules that have been debugged and tested. If strip is executed on a common archive file (see ar.h(3HEAD)) in addition to processing the members, strip removes the archive symbol ta- ble. The archive symbol table must be restored by executing the ar(1) command with the -s option before the archive can be linked by the ld(1) command. strip produces appropriate warning messages when this situation arises. strip is used to reduce the file storage overhead taken by the object file. OPTIONS
The amount of information stripped from the ELF object file can be controlled by using any of the following options. The following options are supported: -l Strip line number information only.Does not strip the symbol table or debugging information. -V Prints, on standard error, the version number of strip. -x Does not strip the symbol table. Debugging and line number information might be stripped. OPERANDS
The following operand is supported: file A path name referring to an executable file. ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of strip: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES

The symbol table section is not removed if it is contained within a segment or if the file is a relocatable object. The line number and debugging sections are not removed if they are contained within a segment or if their associated relocation section is contained within a segment. The strip command is used to remove a standard predefined set of sections from an ELF object file. To remove a user specified section by name, see mcs(1). SunOS 5.11 5 Oct 2007 strip(1)

mcs(1) User Commands mcs(1) NAME
mcs - manipulate the comment section of an object file SYNOPSIS
mcs [-cdpVz] [-a string] [-n name] file... DESCRIPTION
The mcs command is used to manipulate a section, by default the .comment section, in an ELF object file. It is used to add to, delete, print, and compress the contents of a section in an ELF object file, and print only the contents of a section in a COFF object file. mcs cannot add, delete, or compress the contents of a section that is contained within a segment. If the input file is an archive (see ar.h(3HEAD)), the archive is treated as a set of individual files. For example, if the -a option is specified, the string is appended to the comment section of each ELF object file in the archive; if the archive member is not an ELF object file, then it is left unchanged. mcs must be given one or more of the options described below. It applies, in order, each of the specified options to each file. For operations other than delete, if the object does not already contain a section with the specified name, mcs will create a new empty section with that name before performing the specified operation. OPTIONS
The following options are supported: -a string Appends string to the comment section of the ELF object files. If string contains embedded blanks, it must be enclosed in quo- tation marks. -c Compresses the contents of the comment section of the ELF object files. All duplicate entries are removed. The ordering of the remaining entries is not disturbed. -d Deletes the contents of the specified section from the ELF object files. The section header for the comment section is also removed. -n name Specifies the name of the section to access if other than .comment. By default, mcs deals with the section named .comment. This option can be used to specify another section. mcs can take multiple -n options to allow for specification of multiple sections. -p Prints the contents of the comment section on the standard output. Each section printed is tagged by the name of the file from which it was extracted, using the format file[member_name]: for archive files and file: for other files. -V Prints on standard error the version number of mcs. -z Replaces any SHT_PROGBITS sections with zeros while retaining the original attributes of the sections. EXAMPLES
Example 1 Printing a file's comment section The following entry example% mcs -p elf.file prints the comment section of the file elf.file. Example 2 Appending a string to a comment section The following entry example% mcs -a xyz elf.file appends string xyz to elf.file's comment section. Example 3 Stripping a specified non-allocable section Although used primarily with comment sections, mcs can operate on any non-allocable section. In contrast to the strip command, which removes a predefined selection of non-allocable sections, mcs can be used to delete a specific section. The following entry example% mcs -d -n .annotate elf.file removes the section named .annotate from the file elf.file. FILES

When mcs deletes a section using the -d option, it tries to bind together sections of type SHT_REL and target sections pointed to by the sh_info section header field. If one is to be deleted, mcs attempts to delete the other of the pair. By using the -z option, it is possible to make an object file by removing the contents of SHT_PROGBITS sections while retaining the object file's original structure as an ELF file. The need for use of the -z option is limited. However, the option can be used to deliver an object file when the contents of SHT_PROGBITS sections are not relevant. SunOS 5.11 5 Oct 2007 mcs(1)
