## mcs

    mcs [options] files

Manipulate the comment section. mcs is used to add to, compress, delete, or print a section of one or more ELF object `files`. The default section is .comment. If any input file is an archive, mcs acts on each component file and removes the archive symbol table (unless -p was the only option specified). Use ar s to regenerate the symbol table. At least one option must be supplied.

### Options

-a `string`

  Append `string` to the comment section of `files`.

-c

  Compress the comment section of `files` and remove duplicate entries.

-d

  Delete the comment section (including header).

-n `name`

  Act on section `name` instead of .comment.

-p

  Print the comment section on standard output.

-V

  Print the version of mcs on standard error.

### Example

>     mcs -p kernel.o	Print the comment section of kernel.o
